The main features

• this machine is used for super finishing single and double row centripetal ball bearing, single and double row angular contact ball, peach groove whole groove, peach groove half wash, single and double row centripetal bearing convex and concave outer raceway, thrust spherical roller bearing outer raceway. , the machine adopt bearing outside diameter, transverse pressure of not intentional clamping way, high rotary precision of the workpiece.

• the blanking of all types of bearing outer rings is completed at one station. The single and double channels are processed at one datum level through the Angle transformation of servo motor, which effectively improves product quality and processing efficiency.

• the Angle adjustment and swing amplitude of the two channels of the peach shaped little bearing are directly controlled by servo motor, without manual Angle check.

• the workpiece is superfine at the simplex, with coarse whetstone and fine secondary pressure. Whetstone consumption automatic compensation, whetstone too short alarm.

• the workpiece spindle is lubricated by oil mist. The workpiece speed and oscillation frequency are controlled by frequency converter.

♦ machine adopts machine adopts Siemens 828 d control system. The system is stable and reliable, and the parameter setting is input by the touch screen, which is convenient for debugging and management.
