(6) Machining of sections composing the lining of the subway construction in
Budapest.
(7) Machining of artillery shells of large calibers. The shells are
fully processed with the exception of being filled.
(8) Files.
(9) Heavy sections (compartments of blast furnaces-and other metallur-
gical plants, factory stacks, bases for cranes, etc.)
(10) Heat treatment for other factories.
(11) Turning, cutting and milling of pieces of exceptionally large size
and weight.
(12) Special tools such as mandrels, cutting tools, bricket pressing
cylinders, reamers, drills, but mainly tools of unorthodox design and
large size.
(13) Machiring of helical cogged wheels of unusual pattern.
(14) Cable-making machines (for wire ropes, electrical cables, etc.)
b. Current production:
(1) Production in S tember 1953 was running at a value of about 540
to 600 million forints p.a.
(2) Machining of axles of all kinds was running at a total rate of
14,400 axles p.a. 90% of all axles in Hungary are machined in this
factory.
(3) Heavy lathes were being produced at a rate of 420 to 480 p.a.
(4) Turning of the main-shafts of 275 hp. stationary steam engines,
Jendrassik-type 170 marine engines and diesel-electric trains and
coaches.
(5) Among special-purpose heavy machine tools listed in Para. 3 a (4),
this factory produces certain components of a 6,000-ten hot stamping
press which is being manufactured in collaboration with Czechoslovak
and Soviet-German works. This machine tool is intended for pressing
and plates of steam boilers and likewise other components of heavy
plants. It will press pieces of diameters up to 3,000 mm. The
press in question was to be erected at the MAVAG Locomotive and
Engineering Works in Budapest.
(6) The production of sections of tube linings for the subway under
construction in Budapest was slowed down by 90% in July 1953.
c. Production priorities:
It is believed that the order of priorities is as follows:
(1) Machining of axles.
(2) Production of lathes.
(3) Production of special machine tools.
(4) Production of artillery ammunition.

b. Deficiencies in aualit :
(1) The forged axles supplied by Lenin Metallurgical Works of Di~sgydr
are frequently deficient, the material being streaky and containing
embedded particles of slag. In some cases there are cracks. These
faults are discovered only during and after machining, and in many
cases 20% to 50% of the axles are rejected.
(2) The high percentage of waste is due to the following faults in the
metallurgical treatment of the steel:
(a) The charging of open-hearth furnaces is not carried out as
prescribed: either the melting process is not continued long
enough to allow the charge to mix sufficiently and to become
homogenous, or the heat treatment is of too short duraticn and
the temperature too high, resulting in particles of refractory
brick detaching themselves from the lining of the furnace and
becoming embedded in the steel.

(3) Castings show porosity and contain caverns.
Destinations of Products.
a. Export consignees:
(1) Heavy lathes:
It is not known to which countries exports are currently made, but
in the past the following countries have been supplied:
Poland
Rumania
Bulgaria
China
(2) Cable-making machines:
It is known that these have been exported to Bulgaria, and probably
to other countries as well.
be Internal consignees:
(1)'Machining and turning:
Axles, cogged wheels, main shafts and special tools, after machining,
are delivered to the various concerns all over the country for whose
account the work is done.
Axle- and wheel-assemblies of locomotives and rolling stock are
destined to the State Railroads, the Ganz Railroad Car Works, the
Mavag Locomotive and Engineering Works, the GyVr Railroad Car Works
and the Dunakeszi Railroad Car Factory.
(2) Steel sections':
These were supplied to two large projects, e.g. the Sztalin Iron
Works and the subway in Budapest.
6. Transport.
a. All incoming materials and semi-finished products are transported by
railroad and truck.
be The same applies to the transport of outgoing products.
7. Power.
a. Electric power is used,
be The source of power supply is tJe national grid as well as the Berssdvidek
Power Station and the MMtravide Power Station.
c. If the power supply were to fail there would be no alternative source of
supply and production would come to a standstill.

8. Labor.
9.
a. The total number of employees is between 5,000 and 5,500, of whom about
800 to 1,000 are women.
b. The workers live either at Di4sgy8r or Miskolc, or in nearby villages.
c. Transportation of workers is by train, streetcar (Miskolc-Diesgy4r Line)
and by buses. Many use bicycles.
Machinery.
a. The characteristic feature of the available machine tools is that
they consist of unusually heavy units, capable of machining pieces of very
large dimensions such as no other shops in Hungary are able to handle.
They include the following:
(1) Vertical turning mills
(2) Turret lathes
(3) Vertical lathes
(4) Planing machines, the largest of which has a stroke of 35 in.
(5) Milling machines
(6) Boring machines
(7) Special machinery (not a lathe) which makes it possible to carry out
machining on exceptionally large pieces, e.g. pieces with diameters
of up to 30-32 m,
b. The machinery is of many different kinds and includes speciments built
in the factory's own shops, for instance the various machine'tools in
the shop where segments for the subway linings were machined (single-
purpose machines constructed from components of old discarded machines).,
c. The following percentages are an estimate of the age of the machine tools:
30% New, i.e. acquired since 1945.
30% Between 10 and 15 years old.
40% 25 to 30 years old and "home--made", including some entirely
outdated machinery of pre World War I vintage which is the
equipment of the files shop.
d. Measuring instruments, etc.:
There is a well-equipped test room (with automatic air conditioning)
containing all the measuring tools required. But there is neither a
chemical nor a mechanical laboratory. (Analyses requiring a laboratory
are carried out at the Lenin Metallurgical Works of Diisgyfr.),
e. Mechanical handling equipment:
Mechanical handling facilities consist of electric fork trucks and
electrically-driven cranes.

10. a.1a_ty and Quantity Control.
11.
a. The control of efficiency is carried out in the same way as at the
Csepel Automobile Works.
b, The quality control organization consists of 250 inspectors of average
efficiency.
Bottlenecks.
a. No serious bottlenecks in the past 5 years are known, except that in
1952 there was a temporary drop of production caused by faulty materials
of bearings (ball bearings and bronze bearings).
b. No serious bottlenecks affecting current production are known.
c, Points vulnerable owing to their productive importance are:
(1) The machining shops for axles and wheel assemblies,
(2) The shops where sections of large dimensions are machined.
(3) The artillery shell production plant.
4) The heat-treating installation
(5) The cranes are of essential importance in view of the large weights
of products handled. The elimination of the cranes would cripple
production.
12. Securi .
a. There is no armed guard to protect the factory. The nature of security
in the ammunition plant is not known.
b. The elimination of any particular person would not cause a setback in
production. The organization of production and leadership is deliber-
ately deigned so that its functioning should never depend on any individual
person. The sole exceptions to this principle are in the cases of inventors
or brilliant technical experts, but these cases are extremely rare.
c, Identities of leading personnel:
Director:
Palmai (fnu), formerly a manual worker. He is a Party member.
Chief Engineer:
Peter Mausz, and engineer. Has been in this factory for 40 years.
He is a Party member.
Leader of quality control:
Jozsef Schneider, a technical graduate. Not a Party member.
