The table speed of the Model MK-159 vertical. lathe produced by the Kolomna
Heavy-Machine-Tool-Building Plant depends on the weight of the workpiece. If
the workpiece weighs up to C,, tone, it can be machined at a speed of 5 table
rpm or faster. If the workpiece weighs from 150 to 170 tons, it can be ma-
chined at a speed of not greater than 2 table rpm. However, the cutting speed
in machining large-diameter blanks can reach 2C0-300 meters per minute. The
total cutting force [in machining] a 7-meter diameter reaches 20 tons.
In roughing operations, it is possible to use a feed of 5-12 millimeters
per table revolution and a depth of cut of 40-60 millimeters. In finishing
operations, with a wide cutting tool, a feed of up to 120 millimeters can be
used.
At present, Soviet engineers are working on another large vertical lathe on
which parts more thar. 20 meters in diameter can be machined. This machine tool
is scheduled for manufacture in 194
