HIGH EFFICIENCY MACHINE TOOLS
The organic development of our economyunder the Five-
Year Plan, and the planned increase of our industrial
,production to nearly double the volume of 1950, has
I
laid a particularly:heavy responsibility on thnMachine
too! industr Of 'the German Democratic Republic. In
the initial pe hid lifter 1945 we were mainly concerned
with the cleTeloprnent and construction of universal
and multi-pi rposelmachine tools, to enable our indu-
stries to start :With their manifold manufacturing
progro-nmesi in recent years, however, the makers of
.1
machine tool's ; have specialized in the manufacture
of single-puipose :and special machine too 8. It is a
proof of the growing economic strength of the German
Democratic Republic and her rapidly 'creasing
potential, partioularly in the machine tool sector; that
it could gradually t'ake to serial manufacture of special
machine-tools. Ther, Industry is, nevertheless 'Mite and
willing at any ,timel to meet requirements for special
constructions, '
The vast national Construction programme under the
Five-Year P on, :..Which Includes the erection of large
power slat ii.1. ..:ill ng mills, and largo mining enter-
prises, calls for hi:M.1/47-day machine tools for the work-
ing of super-sized: p aces. As early as 1951 there was
developed a turning mill with a turning diameter of
10,000 mm., the otitstanding feature of which Was the
combined steel and concrete construction applied for
the first time.
The fulfilme t of, the energy plan calls fat the con-
struction of 'heavy-duty planing machines with a
planing width of ! 4,250 mm., largo lathes with o
I ,
turning diameter Of 0,200 mm., and a turn ng length
,
of 10,000 mrn.', arywell as rotor spline milling machines
with a maximuzn. distance between the divicing heads
of 8,000 rnm.1, and chucking facilities of the face plates

long, 2,000 mm. wide and 700 mm. deep.
With all those new developments the guiding idea or the
designing engineers has been to eliminate as much us
possible physical exertion of the operator and to
introduce automatic performance wherever' possible.
This task , they were able to solve with unusual success
because, at every designing stage, they proceeded
only in close consultation with their fellow workers in
1
the shops,
1
The close co-operation of the v.ientific research
institutes', with the works engineers and the operators
in the shops, affords our industry the unique possi-
bility to attain the peak, of efficiency in constructional
and works techniques. '
. !Our friendship with thelSoviet Union and the nations
of the People's Democracies has proved particularly
fertile in the economic sector and the interchange of
technical experience and scientific research data. Thus
we were given the full benefit of (lie advanced techni-
ques and vork4iouch experiences of the Soviet Union.
The application of Soviet techniques, as for instance
the high-opeed metal turning method of the master-
turner Pavel Bykov, lies enabled its to strain the
'efficiency of these particular machine .tools to tne
utmost limit of then capacity and to effect a degree of
economy which reputed technologists would never
have believed possible. Through the adoption of these
advanced techniques, which in no way add to the
physical charge of the worker, but, on the contrary,
mean a substantial relief:, our industry has attained an
unprecedented productivity of work. Increased pro-
ductivity of work means saving of man hours and
lowering of costs. Proof of this are the absolutely
competitive priecs, of our machine toms.
Tho quality of our machine tools is further guaranteed
by the desire of our workers, technicians a ml engineers
to collaborate and contribute towards the success of

our great, economic plans, the benefit of which goes
to the community. They are, therefore, united in t.
common pledge to solve the problems put before thorn
and to fully satisfy the customer with respect to
quality workmanship sail production capacity.
The rnanufaLturing plants of our machine tool building
industries unite their decades of experiencc with the
knowledge gained through research work and the
progressive working methods which love emerged
under the leadership of our activists and works
brigades, our inventors and National Prize holders.
This is the basis for the delivery of quality products.
The endeavours of our industry to satisfy every wish
of our foreign- customers, including the most specialized
designs, have the full support of the economic and
commercial policy of our government. The Leipzig
Autumn Fair in 1952 emphatically showed the readi-
ness of the Government of the German Democratic
Republic to promote and to widen the exchange of .
goods on an equal basis with all countries.
The rich display of our industry's goods at the Fair
showed an allround improvement of quality, which
not only aroused the interest of every foreign visitor,
but induced export and import sales, which far ex-
ceeded' those of the Fairs of the lust two years.
Long-term commercial treaties and agreements with
the Soviet Union, the countries of the People's Demi,-
oracles, Poland:Hungary, Rumania, Czechoslovakia,
?Albania, and the People's Republic of China, ensure
Our supply of raw materials for piers to come, and
facilitate lialanced planning of our production for
satisfactory quality and delivery.
This Is also the cause for the increased sales with the
representatives of those countries with which we have
signed agreements regarding the mutual exchange of
goods and the mode of paymant, or with which the
commercial intercourse is settled by means of general
A-wrier agreements , bunking agreements, or direct
cash payments.
2
These very sales are a proof of the .,.-t that. the Leipzig
Fair in 1952 substantially contributed L.) the develop-
ment of a broad international commerce, and espe-
cielly between countries of different economic
systems.
The increase by 192.3 per cent of our industrial pro-
duction through the success of our Two-Year Plan,
and the increase of our agricultural produce during the
present course of the Five-Year Plan will make it
possible by 1955 tu ilia, ease our foreign trade to 290
per cent above that of the year 1950.
The outstanding success of our economy during the
past years proves the wisdom of our economic plan-
ning, and encourages us to continue the same path
gig jeakisfaivial66,44,69,446egiltigruazz. This
*means a constant rise in the standard of living of our
society, the realisation of all technical possibilities
and developments for the reconstruction of our indu-
stry and, last but not least, the delivery of first-quality
industrial products according to terms agreed upon
with our foreign customers.
Irho fact that our economy is free from the risk of
?rises is a guarantee for our partners in trade, who
ish to do business on a mutual basis, that ? owing
to the over-increasing demands for commodities
within our own population?a market is open to them,
which is also ready to receive the products of their
own countries.
The German Democratic Republic offers high-quality
machines and equipment, products of the electro-
technical and optical industries, valuable chemicals,
and other high-quality goods, and has a growing
capacity for buying foodstuffs, industrial and chemical
raw materials, industrial products, as well as semi- .
Stitched products, special machines, textiles, and :.
leather goods.
Thus the Dorman Democratic Republic, through her
foreign trade policies, already shows her desire to serve
the cause of Peace through friendly trade relations on
a mutual basis with all countries.

Thu Lcip2ifif Fair ? a Briciffri to World Trade
,
. During the international Economic Confer:nice in
Moscow in April last year the Soviet Union declared
her readiness to increase herl trade with countries of
' othei economic systems by 30 to 40 thousand million
roubles within the next two Or three years. The Euro-
pean countries of the People's Democracies were
' I
willing to increase their trecln up to 25 to 30 thousand
: million roubles, the People's ,Republic of China from
' 15 to 19 thousand Million reubles, and the Geri-nail
' Democratic Republic from ii) to 12 thousand million
roubles.

Foremost was the Soviet pavilion, two thirds of which
were filled with the products of tile Soviet heavy-
machine building industry, evidence of the rapid
development of Soviet economy.
Among the 30 models of metal turning machine tools,
there were certain now designs which were the topic
of the day for all experts. Of particular interest to
visitors was the semi-automatic gear grinding machine,
the gigantic vertical. turaitg and boring mill, and the
threading lathe model 1:64. The output, as against the
1951 models of thud Mac' inns, is now greatly sur-
passed.

the 25-ton model?and, tile 'eight typos of tractors,
displayed the high standard of motorisation in the
U.S.S.R., which is now well up in the front ranks in
international vehicle building.
IThe same may be said of Soviet agricultural engin-
eering which has doubtlessly taken world lead. Let
us cite examples such as the tractors "Dyeloruss", or
"MTS-1" which perform at operations for grain and
other cultures, also the,gardening tractor, turnip and
potato-hoeing machines, flax and cotton harvesting
machines, the fully motor sod combine "Stalinez-6",
with a daily capacity of 20 to 25 hectare, tile 10-metre
grass mower with a daily: Capacity of 60 hectare, and
the five-share ploughing 'tractor. All these machines

Also Shown were new Soviet petroleum and naphta
products with new admixtures intended to heighten
the qUality and eenstancy of the oil.
The fishing and ,foodstuffs industries of the Soviet
Union exhibited tligh-quality preserves.
The general impression of the Soviet capacities for
production and delivery was completed by the display
of new medical apparatuses, office and accounting
machines, e ectric refrigerators, and a rich assortment
of mass-pm ducts made of glass, ceramics, textiles,
and leather together with the products of the Soviet
popular arts.

with the heavy industry?and particularly with the
leading products of the machine tool building?down
to the light industrics, the foodstuffs industry, etc.
There were heavy radials weighing several tons which,
despite their huge weight, excelled through their ease
of operation and high precision of work. Horizontal
and vertical milling machines, lathes, cold saws and
plate shears stood out an new designs on a high level
of engineering. They also found many buyers during

careful finish, e?,,ee"'-g in their high nrcioionoy, sod
motor-lorries with now designs of the Hungarian
automotive industry, all met with the interest of
visitors from this country end abroad.
The world-renowned Hungarian foodstuffs were
displayed In the same tasteful manner as the products
of the Hungarian textile and leather industries.
More than 2,000 objects were exhibited by the export
trade companies of th 3 People's Republic of 13ulgaria.
The exhibitions of drilling and milling machines, the
air compressed, hammers, the lathes and high speed
lnthes, slipping machines and Diesel engines proved,
together with the exhibits of the Bulgarian electrical
Industry, that Bulgaria has developed from an ogra-
rian country into a .modern industrial nation.
A large part of the Bulgarian stands showed building
materials and chemicals.
As products of the light industry, textiles and leather
goods .were offered. Also on display was the Bulgarian
tobacco industry, the foodstuffs industry, and the
cosmetics industry with their world-famed altar of
roses.
Bulgarian handicraft furthermore offered noteworthy
embroideries and national costumes, ingenious poker-
work and other carved work, ceramics, and leather
-goods:
There was good reason for the general surprise caused
by the exhibition of the People's Republic of China.
Hero for the first time in Europe the products of the
young Chinese machine building industry were offered.
Lathes, drilling machines, milling machines, universal
grinding machines, as well as textile machines, print-
ing machines, power generating plants, and wood-
working machines were among Lko many products
which proved the enormous changes which have been
wrought in the economic structure of China since the
foundation n the Pecp.!es Republic.

There was an extensive show of industrial raw mater-
ials and of the famous domestic products, such as the
world-famous Chinese silks, carpet satins, Hunan
embroideries, wool and cotton goods, etc.
Of the greatest interest were China's world-renowned
mineral treasures like antimony, bauxit, manganese.
magnesium and others which China offers to her
partners in trade.
Products of the arts alicl crafts, surgical instrummits,
medicines, leather goods and furs, and a great many
inciudino, tea, cigarettes, etc.. completed the
picture of the efficiency and export facilities of the
PCOP!ffg Reptibtic of Chin.
The Rumanian People's Republic exhibited machine
tools, precision instruments, equipment for the petro-
leum industry, tractors, and precision ball bearings.
Building materials and glassware, electrotechnical
and agricultural implements, silverware, shoes, toys,
hides, and furs completed the comprehensive offer in
goods of all kinds from the Rumanian People's
Republic.
Symbolic of the new economic strength of the People's
Republic of Poland was the huge double column
vertical turning and boring mill, a gear rim :I metres
high, several plate rolls and section rolls, and other
goods of the heavy and light industries.
The Czechoslovakian industry exhibited in Leipzig
up-t o-date shop equipment and machines for transport
and for energy plants. i mongst others could be seen
steam turbines with a power up to 65,000 kW, and
large synchronous motors for a power up to -15,000 kW.
These were followed up by equipment for the mining
industry mid for metallurgy. The machine tact build-
ing industry exhibited amongst others lathes having
a length of 32 metres and a weight up to 180 tons for
machining workpieces with a weight up to 120 tons and
a circumference of 2,500 mm.
Textiles and shoes, musical instruments, glassware and
jewellery, porcelain, as well as hop, malt, beer, sweets
and other products of the foodstuffs industry were
offered, ready for sale to countries of all economic
systems.
Together with the offer of goods ot the German Demo-
cratic Republic, the 1952 Leipzig Fair has proved
that the perspectives held out by the International
Economic Conference in Moscow with regard to an
enlargement of world trade have a very real econom-
ic basis, and that the Leipzig Fair is par excellence
an important mediator for world trade.

New methods
for super-speed metal removing
are adding to the development
of our machine tools
An essential part of the knowledge about Llie design
and construction of modern 11141Nifillitn capacity
machine tools is based upon high-speed cutting
property for turning, milling, planing, reaming, or
other cut Ling operations. As a source of the eco-
nomical development which the modern machine
tool building has derived from scientifical research
and frOM 'WOO ice we have to look upon our working
people in the manufacturing plants whose new
ethic of work is the starling-point for this new
path towards development. The valuable experien-
ces upon which our work could be erected are due
to the collaboration with the innovators oft he Soviet
Union, to the personal exchange of experiences
micasioned by Pavel Bykov's visit, to totiottrito-
Luring shops, and to the exchange of ',loos with Ito,
CO untries of the friendly People's DOMOCINICIOS. The
collaboration of our workers with the technical
intelligent sin made it possible to evaluate the new
knowledge goblet]. It is to our activists that, the

has induced us that simultaneously with the modern
conception incorporated in our machines, fir the

development has been taken into consideration. The
possibilities in the application of cemented metal
carbids were oftentimes not fully utilized. The new
tooling methods alone ? and particularly on the
old of super-speed metal removing ? have caused
the knowledges gained to be more generally utilised
in the shop.
In developing our new designs we started from the
..naximum values for metal removing based upon
'economical principles and which constantly heigh-
ten the capacities of our products by using very
igh cutting speeds, advantageous cutting tool
angles, utilizing in an economic manner the cutting
materials, paying heed to a long service life of the
tool and to a Minimum of power required by the
machine. These features are decisive for
the ruggedness of general construction,
the safe chucking of both %vorkpiece and tools,
the safe bearing arrangement, of the work spindle,
an efficient gearing arrangement with advan-
tageous spindle speed and feed ranges, and,
finally,
a high driving power.
AL the same time, all the other requirements ex-
pected from modern tnachine tools are complied
with, e. g.
cutting down the machining times by a central
arrangement of the operating elements,
eliminating of faulty controls by foolproof ar-
rangements, extensive automatization of machi-
ning operations and controls,
an increased application of electrical and hydrau-
lic control elements,
taking into account an uniweded flow of chips,
especially in the case of a heightened stock remo-
val capacity,
paying particular attention to the design of those
parts which are liable to wear, bearing in mind
their safe accessability and interchangeability
and, lastly,
paying particular heed to lubrication.
The reliability of service and absence of accidents
are guaranteed by utmost precautionary mea-
sures.
The functional quality as obtained by the first
machine of such designs whi211 are ready for pro-
IIMI-maintained tool cutting edges give a good
dill, formation and are a sign of optima
metal cutting. Discussions and an exihange
of engin( ring practice between activists and the
tedmical intelligentsia with regard to tests
have lead to valuable successes

ducLion is constantly being secured by a quality
control founded upon the quality specifications
according to professor Schlesinger and to the Ger-
man DIN-standards. They are applied in a way that
the interchangeability of the component parts is
ensured. The field of action of the quality control
begins with the inspection of the incoming mate-
rials, the checking of castings, coldpressed forgings
and other pressed parts, of industrial standards and
of purchased parts mut accessories, the inspection
of the single workpieces in the shop including the
inspection after every operation up to the assembl-
ing shop. The Lest for erficiency and increased
efficiency of the aggregates is followed up by the
control of the manufacturing process up to the
assembling shop for the finished product, the inspec-
tion of all functions under practical service con-
ditions, and the drawi;-,g up of test certificates.
Particular attention is paid to the carrying out of
load capacity tests and the effect of the tool corn-

Testing of node:ids
pared with the prod uctIve capacity of the machine
required and with respect to the surface finis!: and
to the accuracy of the finished product; furthermore
to the checking of the handling times, of the safety
tests against faulty control, and danger of accident,
to the inspection of the system of lubrication, the
flow of chips, and to the inspection of the electrical
equipment.:
The guarantee for a machine which answers to these
demands lies not so much in the application of
modern means of production and measuring in
but is essentially based upon personal
and professional engineering qualities of our workers
in the course of production. Skilled engineering
faculties, sensibleness, concientiousness,
an a new ethic of work, utilization of progressive
operating methods. community of interests, [vain
work and a .firmly cemented social basis ? all these
conditions result. in the necessary impulses which
lead to to utmost efficiency and to cheerful work.

OPENSIDE AND DOUBLE COLUMN
PLANING MACHINES
The development of the high-speed cut ing t Dols has
essentially influenced also the design of our planing
machines, and.. has necessarily accommodated them
to the high demands of the practice.
Our range of flantifa cL tire comprises openside and
double column planing machines, namely
openside mocoils il E 800 with a planing width of
800 m?n and a planing length between 2000 and
4500 mm, and the models 11E 1250 and I-1E1700
with planing widths of 1250 and 1700 mm respec-
tively, and planing lengths between 2500 and
12 000 n.,n ; further

double column planer. The standard model is equip-
ped with but one cross rail slide. Another cross rail
slide as well as a side head, or two side heads for
double column type machines, can be furnished as
!
an extra.
The double column planing machine is a new design
and orovided for the utilization of carhide-tipped
tools. This results above all from tl available
speeds for the cutting stroke (8 to 63 ail/min). The
speed for the reverse traverse is variable bet ween 16
and 85 m/min. The pulling power arnounts to
16000 kg for speeds up to 25 m/min. Great Store has
been set in the design of the machine to the ease of
operation and maintenance, to a variet3i of clamp-
ing facilities for the works, to the high bearing
capacity of the bed and of the table With a low
surface pressure upon the ways, to a vibrationless
construction of the bed, table, columns Cross rail,
top traverse, and heads, and to reliable reverse
motion and control mechanisms. By means of [he
rugged construction of the machine, and .owing to
the high table speeds for Lhe working and return
travels and to an extensive application of stepless
feeds, high metal removing cer:,acities for roughing
and finishing operations are attained.

NEWLY-DEVELOPED HYDRAULIC
VERTICAL SLOTTING MACHINES
STANDARDIZATION AND APPLICATION OF CONSTRUCTIONAL UNITS
The application of mechanical, hydraulic and elec-
trical dr ving elements has to a high degree contri-
buted to the development of a production machine
with an all-round efficiency regarding its output,
functicn an.,1 attendance. A good deal of slotting
operations, such like the cutting of gears and key-
ways, require a high cutting power from the slotting
machines, the tools of which are tc. a certain extent
of the broaching type. The tool working at times at
a considerable distance from the ram guide, the.
machine must needs be of a heavy and very sturdy
construe ,ion. By combining the above mentioned me-
chanical hydraulic and electrical driving elements,
it is esst ntial to choose the most efficient driving
means for the main control and other subordinate
motions so as to develop a machine which
has a high cutting capacity and working accu-
racy,
possesses a precise control of both rant and feeds,
is easily to be operated and attended to, and
answers to all shop demands regarding an utim.,
economic utility, foolproof operation and reliabi-
lity in strvice.
A combing out, and simplification of our range of
constructional designs has been intended and care-
fully wdrked out parallel with the above described
Table with indexing attachment and
quick motion
and newly-developed hydraulic type vertical slott-
ing machine. As a result of tb is standardization,
our rangc o manufacture has been restrict ed to
3 types, ,he cutting strokes of which as well as
Cutting speeds, feeds and chief dimensions show a
geometrical progression according to German
standards DIN 323. The modals 710, 1000 and 1400
denote that the maximum (tatting strokes are 710,
1000 and 1400 mm respectively for external slotting
'operations, the corresponding cutting strokes for
internal slotting operations amounting to the half
of that alu e. In order to avoid the necessity of
manufacturing driving pumps, controls, valves and
other component parts of 3 different types, the
,development has been restricted to 2 controls and
driving lumps which are also a geometrical pro-
gression, and which are incorporated into Lhie
,machine in the form of constructional units. The very
'construct'ional dimensions have been restricted to
2 values within the 3 models, whereby for the
'models 1000 and 1400 ale ei the same construc-
tional units, such as regulating devices, feed and
control boxes, reversing and rapid power gear
:mechanisms, have been emplOyed. By this arrange-
ment the operating elements.1, are of the same shape
and sizeJ The operating sides of the divers models
are all alike, so that no difficulties arise, if the
' operate. s of the machines are exchanged:

The lathe models of the range DLZ 400-1000 are
high-effic;ency machines and adapted to the varied
requirements of machine-building. At the same time
they do not ov chook the modern ideas of high-speed
metal-removing technique. A newly designed pre-
selection device for the headstock gearing results in a
simplification of the attendance with the advantage
of boosting the output. The spindle speeds and chief
dimensions are stepped in geometrical progression
according to German standards DIN 323, and so
are the swing-over bed (by which the specific model
is acertained), the width of the bed, and the turning
lengths. The same constructional ideas have been
realized in the internal design of the machines.
Outstanding features of the new WMW-lathes are:
Deep-lying and protected V-guides for the carriage,
large beds, and an optimal reception of the cutting
pressuro.
Thru-guiding ways before the headstock and under
the gap.
Optimal arrangement of the feeding organs between
the cutting edge of the tool and tin: carriage
guide.
Engine lathe model DI.Z 500111
Iligh accuracy for multiple tripping operLtions for
both longitudinal turning and for facing by means
of an overload ball type clutch.
Adaptation of the range of speeds to the divers
requirements.
Arrangement of the main gear mechanisms in the
front part of the headstock, so that a good meshing
is obtained which counteracts the component of the
cutting pressure.
Good effect of the light falling in upon the work-
Organic mounting of the main driving motor in the
axial prolongation of the bed, transmission by

Arrangement for cutting coarse threads.
Arrangement for fine feeds.
Indexing device for cutting multiple threads.
Circular lubrication for the headstock gearing and
forced oil central lubricating system for the main
carriage.
ENGINE LATHES MODEL DLZ 500/11
For the model DLZ 500/11 the spindle
speeds and chief dimensions lave also
geometrical progressions according to
DIN 323, and so have the swing width of
the bed, the turning length, and the inter-
nal constructional design.

DOUBLE COLUMN VERTICAL BORING MILLS MODELS DKZ 2000 x1250-- 6300x2500
The development in the design of double column
vertical boring mills proves very clearly the pro-
gresses made in heavy machine building. Flywheels,
turbine housings, cylinders and similar workpieces
with large diameters and heavy weights are con-
veniently clamped and machined upon the table
of the vertical boring toil!. The table speeds cor-
respond to the cutting speeds which are necessary
for nu-whining with high-speed cutting tools, and
which correspond also to the etatieg spdeds for the
economical utilization of carbide lipped tools. The
1.00ls are located in the tool slides of the right-hand
and left-hand tool heads oil the (A.m.: rail, and in the
side-arm of the right-hand column Ms a special
attachmentt. All tool slides and lumls can be
displaced by hand, by slow feed motion, or by
pushbutton controlled quick motion. Speeial at-
tachments on the feed boxes of the cross rail permit

threading operations with the right-hand head, and
taper turning operations with the left-hand head.
The whole vont 'el of the mimhine, including the
setting of the table speeds, ensues from a central
desk beside an, machine. Quite independently of
this, the control of the slow feed and quick motion
of the heads ma) be effectuated either on the heads
themselves, or through the feed box of the crosS
rail.
The large diameter and widely dimensioned way
the table causes, in conjunction with a earefullY.
designed circulating lubrication for the coolant, LIM
friction heat to keep within the admissible litnits
and to obtain a high total efficiency of the machin.
The table speeds are set by an electro-mechanical
gear mechanism, they are, moreover, steplesslly
variable at the ratio 1:3. The change of the speeds
is carried out by pushbutton control on the central
desk. An outstanding and ingenious design has been
embodied in the feed gear mechanisms for the crosis
rail and the side arm. The superposition of the sloW
feed motion and of the quick motion will allow at
any time to make use of the quick motion in ho.,11
direetions, even if the feed has been engaged. The
feed motion of the cross rail heads is limited bjy
stops, and ce aius automatically without any sub-
sequent movement. It is also possible to stop the
feed motion at the heads by hand at any given
moment. The quick motion the heads is inter-
ru if the feed motion in the same direetion is
automatically engagq1, and can only be usad for
the opposite direction.
ROLL LATHES MODEL DXW
Lathes for turning heavy rolls are built in 3 models
having a swing over bed of 550, 950, and IZO rum
respectively. The model as illustrated is of the
biggest heavy-duty type and a new design. The
outward appearance of the in gives evidence
of the modern engineering thoughts embodied in the
design, in conjunction with practical experiencies
gained by the collaboration with rolling mills. The
machine has a headstock, a two-way bed, double
tool rest and a face plate type tailstock; it is manu-
factured with a swing of 1350 min and a turning
length up to 8000 rum. If so required by the work-
ing conditions, the machine rnay as well be equip-
ped with a centre toilstock. The headstock rests
upon the base and is connected with the bed. It
carries also the driving motor. Even the traditional
control cabinet, forms a unit with the boadstack.
The switches for the oil motor for the gearing, the
main drive and the pushbutton control are located
on the end side of the headstock; they may he 11 t

As a rule, turret lathes are employed for small
batch production of at ?least 15 to '10 pie-
ces. It has proved to advantage, however,
to use turret lathes for batches even still
smaller, e. g. of about 10 pieces each. The
drum type design permits the application of
a great man: standard tools, so that the set-
ting time is favourably influenced, and low
production Limes per piece are obtained. The
employment of automatic lathes for small and
medium series production results nprofitable
on account of the high setting times. Even if
the setting operations of single or multiple
spindle automatics are relatively simple ones,
yet the setting times will always be higher
than for the turret lathe. The drain type
turret lathe is an extremely versatile machine
and, therefore, indispensable for nearly all
production parts in the precision mechanics,
in the general engineering and machine tool
manufacture, in the railway carriage, loco-
motive, or ship building industries, electro-
technics, for the manufacture of fittings and
other parts. The drum type turret lathe is
particularly fitted for bar work and for
medium sized chuck work. The characteristic
feature of the drum type turret lathe is (hue
arrangement of the head for the location of
the tools. This drum type head is horizontally
arranged, and possesses 16 turret tool holes,
the top one of which is flush with the centre
of the workspindle. By these means a (rans-
verse rotary.movement of the tool is achieved,
and no additional cress slide for facing,
recessing, or cutting of operati(ms is required.

SPUR GEAR GRINDING MACHINE
WORKING BY THE GENERATING
PROCESS MODELS ZSWZ 315 AND 500
With the aid of these machines gears may be ground
which have different numbers of teeth and module,
and sometitnes even different angles of presouire, by
employing the some grinding wheel without the
least distortion of the profile. The machines are
provided with it sitaple device for dressing I he
profile of the grinding wheel and are, therefore, very
versatile machines. The involute gears thus ground
have exceedingly good running qualities and admit
to a large extent small errors in centre distance.
'rho machine grinds involute gears with any cor-
rection of the teeth desired.
The application of Llie involute tooth system is
inasmuch go! vantageous as the geometrical law of
the involute is realized with relatively simple
kinematics, and because all involute profiles are
generated by straight-flanked tools. The method
or operating for generating on involute is called the
generating process. This process is of great advan-
tage for the milling and shaping of gears, and for
the grinding of tooth flanks on the gear generating
grinder oil account of the tool savings attained
by it.
The model ZSWZN :315 is a special design Lc grind,
besides standard spur gears, also Fellow pinion type
cutters. The upper part of the machine is swivelling
and adjustable up to 8 degrees.

Every modern working process in a manufacturing
shop ought to have, besides the realization of the
practical knowledges gained, also a sound scientific
basis. Only by a close co-operation between theory
and practice, the necessary conclusions can be
drawn for the utilization of all possibilities. Com-
paring the structure of surfaces which have been
produced by different kinds of finishing and super-
finishing operations, reliable conclusions can he
drawn regarding the results obtained by honing.
The critical inspection of high-quality suzfaces is
very difficult when done merely visually. It wasn't
until the non-cutting process, and the mew tiring of
super-quality surfaces by means of the irerference
microscope were introduced that exact qata could
be got with regard to the structure of sarfaces that
had been finished and super-finished. Interfereace
microphotographs show distinctly the crosswise
grinding due to the compound honing motion, and
which is visible to the naked eye down to 0,00025
to 0,0004 mm max. roughness. This crosswise grind-
ing, just perceptible to the eye, is essentially the
cause that engineers less versified upon the special
honing field entertain a distrust to honing, thinking
that the surface finishes obtained do not answer to
their demands. The honed surface, however, will
fullfill more than a superficial inspection does
20
HONING
suggest. If surfaces have the marks caused by
machining directed uniformly, as in the case of
plain or internal grinding operations, so that the
shadows of the doubtlessly still existing "ridges"
will fall into the same direction, then the naked eye
is deceived by apparently very smooth surfaces.
The crosswise grinding is more distinctly visible as
an effect of tbe shadow. The greater irregularity of
the surface is, however, only apparent. The truth
is that by applying the honing process for the
finishing operation, we very nearly approach the
conditions that oxist for glidi3g machining members
having run in. There is no dialbt that the surface
of the honed part poSaesses the most compact
structure. A honed surface may be exposed to a
much highly specific suriece pressure than another
surface that has been only ground or finish-turned.
By the high surface finish the coefficient of friction
is reduced, and optimal gliding qualities are ob-
tained so that the efficiency of the machine and its
service life are heightened, whilst the driving power
is reduced. These advantages will be still more set
off, if both gliding surfaces are finished by honing,
e. g. the bore and ?thc shaft, the cylinder and the
piston, or .the control box and the slide valve.
The same importance must be imparted to the
external homing process.

When compared wills LIM thread milling machines
employed up, to now, the fly-cutter type milling
appears more advantageOus, because it results in an
increased output, a high-grade finish, and a long
life of the cutting tools. I
The tool which has the !form of an inserted tooth
milling cutter revolves round the workpiece. The
latter is passed through the fly cutter tool whilst the
operation is going on. f3et h the axis of the tool and
of the work are eccentrically dieplaced the one with
regard to the other, during the milling operations.
The axis of the tool is fUrthermore inclined by the
amount of the helix angle of the thread towards he
axis of the !workpiece.I The circular cutter head
incorporates on its circumference 4 carbide-tippea
fly-cutters, arranged in One plane, each of which is
adjustable ard may be individually replaced.
The high Metal removing capacity by fly-cutter
milling is dUe to the application of carbide-tipped

cutting tools which have a high resistance to heat,
and permit thus high l cutting speeds resulting in
a relatively large chip production. In consequence
of this, dry cutting is admissible which eliminates

MILLING MACHINES
MODEL DUPLEX-59 ORIGINAL RUHLA
The universal toolroom milling machine model
Duplex-59.priginal Ruhla corresponds in its design
to the famous universal toolroom milling machine
model Duplex-53. It, has, however, a more rugged
construction, longer working travels, and a higher
production capacity. Th its model 59 represents the
necessary further development of model 53 by
having the same universal field of application as
the latter, and giving the possibility to machine
heavy workpieces. The machine model Si) has a
compact and quiet outward appearance. In order
to guarantee the titilization of modern carbid tools,
special attention in the design of ilk: machine has
been paid to the ruggedness and rigidity of the
eolumn of the machine.
There are 8 spindle speeds in geometrical progres-
- filen available; 52 to 1200 r. p. in. for the horizontal
spindle, and SO to 1200 I. p. m. for the verical
S pindle.
The control of the main gear mechanism and of the
feed gear in with 8 feeds and individual
drive is accomplished by cam control (single hand-
wheel control). The head is driven by a three-phase
current motor ha'ying 2,2 kw power, ant: the feed
gearing by ii motor having 0,63 kw power. All spur
gears of both geir mechanisms are hardened and
have ground tooth Mmes.
The front bearing of the horizontal spindle is an
adjustable plain friction bearing, whilst for the
rear bearing anti-friction bearings are incorpo-
rated.
The vertical milling head is mounted on therm type
overarm and may 1)e swivelled by 360 degrees. For
horizontal milling operations the head is not Laken
off, but brought into a horizontal position, in order
to move back the overarm. The motion of the con-
trol organs corresponds to the respective motiors of
the slides, and ette and handiness of operation is
elrillred by the centralization and ingenious ar-
rangement of all operating elements. The power rise
and fall traverses of the vertical slide as well as the
right and left traverses of the longitudinal slide aro
operated Ity one control lever only. A new design of
angulc.c V-guides for the longitudinal slide ensures
a Idgh working accuracy, even umler severe service
conditions. The nose of the horizontal spindle is
designed to receive 1111ISA-steep angle taper
and the nose of the vertical spindle an 1SA-steep
angle taper l'"4"?

JIG BORING MACHINE BL 315 x 450
The ever increasing demand for high-quality gauges,
jigs and precision component parts for I he require-
ments of modern duplicate production in machine
building, and also for mass production, have led to
the development of a jig boring machine according
to the latest researches and experiences. The new
jig boring machine surpasses all systems known op
to this day with regard to its measuring and working
accuracy. A special feature is the combination of a
coordinate measuring machine having optical fine-
measuring devices and a precision and fine boring
machine. The control of the machine is fully cen-
tralized so that all control levers are conveniently
operated, and adjustable from the operator's
stand. For machining small workpieces the operator
may also be seated. By special arrangements in the
design of the machine, errors caused by setting are
eliminated. There is no need for the operator to
carry out calculations, such like summing up of
measures.
THE OPTICAL MEASURING SYSTEM
The measuring system applied affords a direct
reading. on the glass scale and rack type adjustment.
In opposition to the measuring system with screw
adjustment, it has the advantage of being resistant
to wear. Tho displazement of the measuring slides is
read off by means of spiral microscopes and revers-
ing collimators on glass scales having I rum-gra-
duations.
Tho subdivision of one millimetre ?mews in the
spiral microseope by rotating a spiral plate, per-
mitting thus to read off one it of a millimetre. In
order to eliminate Lilting errors, which are unavoid-
able after a certain wear of the machine, the Eppen-
stein principle has been adopted, so that for the
whole life of the machine and for a medium ma-
chining plane of the workpiece the working accu-
racy is guaranteed. By these means the principle of
Abbe which demands "measuring in ti e respective
measuring plane" is approximately complied with.
For a working height of 138 mm abeVe level of
table the principle of Abbe has been attained. In
order to avoid any mental calculation 'work from
the operator's part, an abrolute zero position of all
measuring organs at the beginning of the operations
is possible.
The millimetre dividing drum for the coarse ad-
justment may be positioned to zero i t any point
before beginning the operations, i. e. after clamping
the workpiece and aligning the latter by means of
the setting microscope or centering device. The spi-
ral microscopes, too, have a device for the Zero po-
sition and avoid, therefore. calculation work.
If the measurements in the drawings are entered by
means of the coordinate system, the direct arith-
metical value may be used as value for setting. To-
gether with the coarse milkman: smile,! another
coarse scale has been coupled which indicates the
respective final position of the table. By this method
the mounting of the workpiere at the right point of
the table is facilitated. Switching on LI e microscope
and scale illumination is done by a pi sin button at
the control desk. A time relay incorporated in the
machine switches off the illumination after approxi-
mately 20 seconds, minimizing thus art undesirable
? heating of the measuring tools. All lamp sockets are
easily accessible from without, and eXchunge muy.
take place within a few seconds.
The circular dividing tables (special attachments)
The machine is equipped with a rich standard at-
tachment and guarantees, therefore, an adequate
utilization for all operations that m9( be met with
in the shop. The flexibility of the Machine is still
heightened by special arrangements, of Which hit-
ters the two circular dividing tables are worth men-
tioning.

FINEBORING UNITS
The development of fineboring units has followed
the pat i of the constructional unit system, so that
other s ngle purpose machines for heavy workpie-
ces, or quickly convertible universal single or multi-
spindle machines for series production, are avail-
able from the constructional elements.
The fineboring unit, consists essentially of a square-
sectiotmd main body, t m feed sleeve of which has
been wronged eccentr catty with regard to the
spindle, so that the smallest distance between cen-
tres (110 nun) is obtained by using two boring
inuts with left and right-hand arrangement.
The feed motion of the feed sleeve together with the
spindle is a hydraulic one, and has an infinitely vari-
able conl?rol between .10 and 200 in to per minute.
The maximal feeding stroke amounts to Z00 nun.
The stroke is limited by a finely adjustable posit ice
stop which can be easily exchanged. The quick
motion feed and reversing stroke amount to approx.
2 metros per minute. The control of the feeding
movement ensues through an incorporat ed controller
and a control jack. By transposing the control
members, every boring unit can be converted from
left-hand arrangement to right-hand arrangement,
and vice versa.
In order to maintain the small play of the aijustable
friction bearings of the spindle, a circulation system
has been applied for the spindle. The circulation of
the lubricant it hereby watched through an in-
spection glass.
When utilizing fineboring units for single purpose
and for universal machines, columns are usually
employed that have one or more vertically adjust-
able knees to receive the units, each of which pos-
sesses an individual drive. The assembling of single
purpose and universal machines from single con-
structional elements by means of the constructional
unit system and the utilization of bottom drives
facilits e the arrangement of fineboring units in any
position required by the workpiece, amongst others
also angular positions and, in special cases, also a
vertical arrangement.
These possibilities may still be widened by the use
of drilling units and, if necessary, of facing units.
The control and operating members are conveni-
ently arranged, so as to be at, the reach of the
operator.

MACHINES AND EQUIPMENTS FOR THE MANUFACTURE OF SHEET METAL PACKINGS
Shoot metal packings are made in a variety of kinds,
and may hc subdivided by the various machines
and equipments necessary for their manufacture as
follows:
tins, round and other shapes, for meat, fish, milk,
vegetables etc.
plain tins for turned-up or hinged lids for cocoa,
coffee, cakes, chocolates, and sweets,
canisters of all shapes anti sizes for mineral oils,
benzine, and vegetable oils,
round containers with pressed-in lids or with scre-
wed caps for liquid or granulous contents,
buckets having cylindrical or conical shapes.
This subdivision is restricted to the principle shapes,
and may be considerably extended.
Tho manufacture of the plain tins having a stuek-b.,
or turned-up lid is usually accomplished in 2 ope-
rations (blanking/drawing and trimming/beading
operations). All the other tins, however, are made
of several component parts, and require, therefore, ,
a whole sequence of metal working machines. On
the other hand, the type and number of these ma-i
chines depend upon the shape, size, and design of
the metal paeltings to b. manufactured and the
hourly or daily output wanted. In conformity with
a small, medium, or great output, and the kind of
tin in question, very different machine plants will
result.

TOOLS FOR NON-CUTTING SHAPING
Blanki.ig, drawing, bending. and embossing tools, pressing tools, pressure die-casting tools, tools for pressing
layer materials, pressure die-casting dies (Injection moulds) for thermoplastic masses, rubber moulds, press
casting moulds, brass forging dies
Blanking, drawing, bending, and embossing tools
Our range of manufacture of small tools comprises
blanking, drawing, embossing and bending tools,
moulds for hot-pressing, single blanking dies, mul-
tiple blanking dies, engraving dies for the cutlery
and hardware industries, and tools for multiple-die
presses for non-cutting shaping. Heavy tools are
made up to the largest dimensions as blanking,
drawing, bending, and stamping tools for the vehicle
and body building industries, for the manufacture
of hearths and other articles. When encountering
any problem regarding the mass production of ar-
ticles made by cutting, drawing, stamping, or
punching operations, and the manufacture and sup-
ply of tools belonging to them, it is indispensable to
bear in mind the working conditions prevailing.
Pressing tools, tools for pressing layer materials
Pressing tools are made as single or multiple moulds.
The size of the tools depends upon the article to be
manufactured, the demand required, and upon the
presses employed. Our range of manufacture com-
prises tools for pressures bet,veen 10 to 500 tons and
for workpieces with a weight up to 4000 kgs. We
guarantee an outstanding quality for the pressing
rnoulds and dies manufactured. Thus the inner parts
which come into contact with the moulding com-
pound are made of high-quality steel with a high
degree of purity, and are free from shrinkages. The
surfaces of the die must be as hard as glass, resistant
to wear, and mirror-finished. When employing case-
hardening stb, 1, the ease must be 0,5 to 1 mm deep.
Die-casting verimen
If the tools are treated carefully, a single type mould
will have a life, of approximately 40000 to ,50000
pressed parts, and that of a multiple die will even
last correspondingly longer. The heating of the die
ensues electrically or by hot water. Unobjection-
able parts can only be guaranteed, if the prescribed
temperatures and the required pressures are main-
tained and if the dies undergo a careful control and
Maintenance. The control of temperature is carried
out by a regulating device, and the setting ,of the
prescribed initial temperature by melting 'salts.
Thus, for instance, 160 to 170 degrees C must be
maintained for the working of a rapid moulding
compound. Consequently, a tolerance in tempera-
ture up to 10'' C is admissible. If the moulding ma-
terial is acidiferous, the tolerance in temperature
must not exceed 2 degrees.
In order to obtain a maximum life of the die, and
to guarantee the scheduled output, the calculated
working pressure has to be kept within close tole-
rances. 'rho plunger of the press is provided with
outlets for the moulding compound to flow Off, or
it has a correspondent play, so that an overpressure
is avoided by the superfluous quantity of moulding
material escaping.
At the beginning of the work attention must be paid
to paint the heated die with die wax, until the pres-
sed parts can be detached from the die without dif-
ficulty. Remnants of the moulding compound, or
Of the pressed parts sticking to the die, should only
be removed with a piece of pointed round brass.
The die is filled with loose moulding compound, or
with tablets. If the plastic product is acidiferous,

the die must be made either of acid. proof steel, or
it must be nerd chromium plated. The latter pro-
cess has proved the most advantageous up to now.
Which steels are to be employed, depends upon the
kind of moulded plastic, since the latter varies in
the working pressure between 250 and SOO kg/cm/.
These pressure conditicns have, therefore, to be
taken into account when designing the dies. Finally,
attention must be paid as to whether the pressed
part has the shape of a plate or vessel with a cf-m-
siderable rise, because the shape of the parts to
be manufactured also greatly influences the pres-
sures applied.
Pressure die-casting took
are employed for parts with thick walls or with
many or thin metal inserts. For these dies the pla-
stic compound is filled in loosely, or in the form of
tablets, into a feeding cylinder and having reached
the necessary temperature, is pressed at one pres-
sure through one or more nozzles into the cavity of
the die. The advantage of this process lies in the
fact that the compound will increase in hardness
very quickly, so that the very short piecetimes ob-
tained guarantee the profitableness of this working
process.
Pressure die-castings with thick walls
As an example let us look at a telephone receiver.
Surf) a receiver is made with the aid of a duplex
pressure de-casting die within 1 or 2 minutes, using
tablets which have been preheated in a high-fre-
quency preheater. The press moulding process re-
quires for the same part two press moulds; namely
one for pre-moulding the profile tablets, and a fi-
nishing mould for the receiver proper. The produc-
tion time per piece for the manufacture of the recei-
ver by this process was aprox. 6 to S minutes, from
which thu advantage of the first-mentioned pres-
sure die-casting die is evident.
Pressure die-castings with many or with
thin metal inserts
These complicated parts cannot be manufactured
oftentimes by press moulding, whilst theM are no
difficulties when applying the pressure die-casting
process, because the metallic parts can be laid in
at first very conveniently, and then the moulding
compound is pressure cast through the nozzle with-
out endangering the metal.
50
There are pressure die-casting dies for presses with
top and hot tern type plungers. The world rig process
is for both types the same. For t top type model
the moulding compound is poured from above into
the filling cylinder, the plunger moves from the top
towards the bottom, and theram performs the work?
fag process closing at the same time the die. The
bottom type model has the (lie filled in the same
manner, the closing of the mould, however, is per-
formed by the ram,and the die-casting operation by
the plunger of the press.
Pressure die-casting tools are made for pressures not
exceeding 1200 kg/cm i (17000 psi). These calcula-
tions result in a normal die-casting process with the
necessary times for hardening and setting. The lar-
ger the section of the nozzie is chosen, the snuffler
will be the surface pressure, the longer, however,
the above mentioned times. As the hardest wear is
to be stated at the contours of the nozzle, a material
must be employed which is resistant to wear, or a
case-hardening steel with a thick case. If possible,
the contours of the nozzles should be arranged inter-
changeably and bo made of super-speed steel or of
cemented metal carbid. The maintenance and opera-
tion of the pressure die-casting die has to be carried
out with the same care as for the usual pressure
moulds.
Press tools for working layer materials
are employed for the working of layer materials
(plywood impregnated with main). The material to
be pressed is piled up in plates, and then laid into
the mould. It is then pressed under high pressures
nud simultaneously cut off.
Press tools for working layer materials are made of
special quality case-hardened steel. Special expe-
riences are needed for the design of the cutting edge.
Injection moulding dies for thermoplastic compounds
As is usually known, the material for thermosetting
compounds has to be filled into an open and heated
mould. Thermoplastic masses, however, like Trolitul
(Polystyrol). Luvican, Plexigum and others can be
injection moulded. This process is characterized by
the fact that the die is already closed before being
filled with the plastic material. It is evident that
by the elimination of any movement of the parts
of the die during the moulding process the shaping
facilities become greater.

Sometimes which have no haNlened moulding

the considerable wear, the dies are often damaged
owing to the very high pressures during injecting

marks at definite points of the die.

Rubber moulds, pressure casting tools,
brass forging dies
Bobber moulds are made for mass production or as
single moulds for larger workpieces and are not har-
dened, because the pressures wanted do not exceed
2001(g/cm= (2800 psi). The heating of the tools is
accomplished by hot, water, or electrically.
Pressure casting tools
are developed in conformity with patterns, draw-
ings of the parts, or drawings of the Moulds. Only
alloyed high-quality steels for hot working with a
high drawing (tempering) temperature up to
000 degrees C (1100' Fahrenheit) can be employed,
because an annealing of the tool due to its getting
very hot during the operations must be prevented.
Brass forging dies are also made of alloyed high-
quality steels for hot working, in the same muon-
ncr as the above-mentioned pressure casting tools.
