В наличии

Description

CLASS A ACCORDING TO GOST 8-82

Are used in small scale and mass production of industrial enterprises, at individual workshops.

ADVANTAGES:

finishing grinding is not necessary due to micron accuracy precision;
ability to perform a variety of turning operations, as well as cutting all kinds of threads;
stepless main drive (2800 rpm);
wide range of longitudinal and transverse feeds;
support rapid movement at idle;
ability to perform highly precise processes using the most advanced tools.
