The machine has a layout with a rotary (dividing) round table and two (upper and lower) wheel heads with a vertical axis of rotation.

The base of the machine is the bed. All units, except for the turntable, are placed either inside the bed or on the top plate of it and are covered with a casing and covers, which makes it possible to work on the machine almost safe.

On the right side of the bed the steering console is mounted, which houses the CNC "Sinumerik 828D", behind the panel there is an electric cabinet, the left side has the cooling, and the rear side - the hydraulic station.

Processing simultaneously of two planes of parts located in the cells of the cassette is performed with the feed to the embedding of the upper wheel head when the oscillating movement of the cassette. The parts are processed with two diamond wheels mounted on the wheel heads. Both spindles can rotate either in one direction or in different directions. The grinding wheels spindles rotation frequency is regulated by frequency current converters. The lower wheel head is rigidly fixed to the machine bed.

The spindles are mounted on 4 radial and 2 thrust rolling bearings. In the front part of the machine there is a working turntable that performs automatic loading into the cassette, delivery to the work area, oscillation, manual control zone and unloading of parts. Four cassettes are installed on the desktop for placing the processed parts in them. The work table has a 90° positional dividing turn with changing the position of the cassettes: loading, grinding, manual control position and unloading of parts. The parts are unloaded to a special device. Parts are loaded into cassettes from the drive automatically. Control and correction of the size processing is performed by the operator in manual mode. Programmable coordinate V-vertical movement of the upper spindle of the wheel head.
