The machine is designed for grinding on the details of splines of straight and involute profiles.Spline grinding is performed with the use of cutting fluid, abrasive grinding wheels directly edit on the machine.
 The technical capabilities of the machine enable to perform with the use of additional options operations of grinding of indexing plate slots, spur gears and other similar operations. The CNC SINUMERIK 840D DSL device (Germany) complete with digital drives of the coordinate axes ensures high-quality machine control and its reliable, smooth operation.
Grinding of the surfaces on the machine is carried out by the control program.

As drives on the machine applied linear synchronous motors, synchronous motors, synchronous circular (torus) motor, backlash-free ballscrew drives. Axis is along closed preload guideways.
This equipment is also equipped with a system of orientation that binds the workpiece (angular and axial) to the machine coordinate system and allows to evaluate the quality of the workpiece, stepping on the ground and quality of the finished part.
