Two-end finishing device

Automobile brake discs (Fig. 1) are important parts of automobile brakes. They have strict requirements on dimensional tolerances, shape tolerances, balance accuracy, surface roughness, etc., and the brake discs have various specifications but similar dimensions.

It was changed to fixed double-sided turning tool cutting, and the end faces of the brake discs A and B were cut in the radial direction. Retreat
