Circular grinding machines models 3L151, 3L152, 3L162, 3L163 and 3L164 are used for outside grinding of both cylindrical, and conical surfaces. The first occur at products as shaft, and the second - at products having small conicity.

Accuracy rating – VPO state standard specification 8-82.

Types of the grinding works which are carried out on the machine:
longitudinal and cut-in grinding on manual control;
longitudinal and cut-in grinding on given sizes on a semi-automatic cycle;

The considered equipment is suitable for mass production of any scales (from small to large).
Regarding influence of climate and other factors of a circumambient the equipment is made performed by UHL4; category of placement 4.1 according to GOST 15150.

Structure of an electrical equipment:
PLK "DELTAELECTRONICS";
a drive servomotor for giving of a block;
an electronic flywheel (it is a steering wheel-enkoder) for giving of the wheel head;
HMI (is deciphered as "the human-machine interface") allowing to carry out directly from the corresponding terminal debugging, configuring, and also control of the machine.

Constructional features of a semiautomatic device.
a Number of kinematic chains in the equipment makes the movements of the following character:
the spindle of the wheel head rotates;
the product rotates;
cross the wheel head moves;
the table moves (both automatically, and manually);
the tailstock pintle is brought and taken away (manually or hydraulically);
cross diamond of the correct device moves.
