REDEcIGft HEAVY MACHINE TOOIS -- Moscov, Za Ekonomiyu Materislov, Mar 53
Formerlq, the Model 5330 gear bobbing machine, a product of the Kolomna
Heavy Machine Tool Building Plant, was manufactured with two elides. One slide,
knovn as the main slide, was for machining genre with hobs or cutters with
radial feed and the other, known as the tangential slide, was for machining
gears with tapered hobs or fly cutters with axial feed.
Experiments were conducted to discover vhether the two slides could be
combined into one. This was found to be possible by increasing the rigidity
of the :;lido for axial tool. feed and by reinforcing the tool-arbor support, As
a result, not Only was the design of the machine tool Improved but the folloving
amounts of metal were saved: 617 kilograms of teat iron, 584 kilograms of steel,
and 75.6 kilograms of bronze. Ia addition, the total weight of the machine t:~l
was decreased by 1,200 kilograms and the number of parts in the machine tool by
757? At present, the new elide is in the manufacturing stage.
An improved design of the back-column slide has increeeed the rigidity of
the unit and decreased its weight by 70 kilograms is Model 5330 and 400 kilo-
grams in Model 5353.
A new design oY cabinets 'for the electrieal equipment and. control panels
for machine tools has been developed at the plant. Ae a result of replacing
light-bulb fittings with purchased plastic ones and ea a result of a better
errangemeat of the electrical equipment, the weight of the unite has been de-
creased, a saving in copper affeiate'3, and the labor comumpcioa in installing
the electrical equipment x'educed: The nev design oP cabinets and control
panels has made it possible to reduce the weight of gear bobbing machines by
F3:k~lograms and of .the Model 1165 vertical boring mill by 15 kilograms,

it possible to save up to 700 kilograms of metal per lathe. According to a
report, ip 00-iT_p6971, 125 kilograms of steel can be saved by thin measure)
At.*he ear time, is has been found that the bronze spindle bearings can be

measures for saving metal into production. The experimental models are manu-
factured and tested under production conditions, together with the fulfillment
of .the production program. Naturally, the me.nufacture of an experimental model
coupled with?the pressure of fulfilling a basic plan complicates good organi7ra-
tional.order. The answer to this problem .would be to set up an experimental
shop or section at the plant which would speed up and facilitate the manufac-
ture of experimental models,
