The invention relates to mechanical engineering and can be used in the metalworking industry, where finishing of high-precision spherical surfaces of parts is required.

The purpose of the invention is to improve the processing accuracy and productivity and expand the technological capabilities of the device by machining parts with a small surface, spherical surface.

of the machine and through bearings 2 with clips 3 and 4.

Thus, rolling is transmitted to this device by means of a contour with rolling bearings mounted on it. During machining, the coupling of the lap to the part may occur, which is the cause of the jamming forces. The presence of bearings 2 rolling leads to the opening of the clips 3

FIG. T shows a device for sub-0 and 4, which, in turn, reduces the pressure of exact spheres, a general form; in fig. 2-faceting on the part and eliminates jamming of the finishing circuit. H The adjusting device consists of the me- Thus, the proposed device of the periodic oscillating motion automatically tracks the mode of treatment with the bracket 1, the bearings 2 of the cathode (ground pressure on the part, , the top 3 and bottom 4 clips, w, een lapping),
