NEW MACHINE TOOLS fOR RAIL MILLS AND TRACTOR PLANT
The process of finishing rails on rail-rolling mills has until now been
limited and labor-consuming due to the. small degree of mechanization.. The
construction of modern automatic rail shops required a radical change in the
machining process,, and the .designing of machine tools which would permit auto-
matic handling of rails being machined.
Rail-milling and rail-drilling machines have been designed by Stalin
Prize winners G. P. Aristov and R. F. Novosad. These machines gu_?antee con-
tinuous-machining of the rails and their completely automatic transportation.
The ICOI rail-milling machines are built for a complete pass of the rails, with
simultaneous milling of both ends of the rail. .The 1A85 and 1C21 rail-drilling
machines for machining round and oval holes are equipped with hydraulic devices
which automatically feed rails to the machine and eject them upon complt;ion of
machining. All machines are provided with hydraulic chucks and a completely
automatic operating cycle.. The machines are exceptional because of their in-
creased durability, rigidity and reliability. As a 'result of the automatic
process, the labor input is only one-fourth that required by the latest American
machine tools.
Gor!kiy Milling Machine Plant engineers B. I. Petyashin, V. A. Anufriyev,
B. N. Muravin, M. M. Ivanov, and N. M. Khitrun were awarded Stalin Prizes for
designing original high-duty universal high-speed milling machines, including
a group of unified bracket milling machines, Types 6N82, 6N82G,6N12, 6N83, and
6N13.
Chelyabinsk Tractor Plant Gets New Machine
Heavy milling machines were also designed. Among these are the Type 6991
special face-Tilling machine weighing 130 tons for high-speed surface milling
of columns for high buildings and the tower for the Palace of Soviets; a hype
GF-75 plano-milling machine for high-speed ai.lling of left-and right-hand truck
frames fiart of a caterpillar mechanis7 for the Chelyabinsk tractor; and the
Model A 664D 4-spindle piano-milling machine; which completes a series of plano-
milling machines (A622, k663 and their modifications) and combination units.

Mechanical removal of chips has been perfected on the. Model 6991. High-
speed milling with cylindrical mills has been used for the first time on-the
Model GF-75 machines.Fbr faster and more economical manufacture of-heavy
machine tools, standardized parts have been extensively adopted. Manufacture
cf bronze worm gears from bimetal castings is saving nonferrous metals.
A group of Stalin Prize winners, I; Ye. Burshteyn, N. N. Ognev, L. S-.
Slonim, and D. Ye. Leksakov, have developed and introduced a new method of
manufacturing files. As a result of their work, an automatic line for the
manufacture of billets for files, seven new-type machine tools, and 50 new-
dseign fixtures and tools have been built. Four new methods of machining were
developed which have overall industrial importance: The effectiveness of the,
new technology, equirment, and tools is shown by the follo ring:,., production of
files can be increased five times, cost of machining cut three times, and pro-
duction area decreased four times. A sharp improvement in working conditions
can be achieved. These innovations have already been put into operation at
file-making plants.
