Technical Field

[0001] The utility model relates to the technical field of machine tool bearing rings, in particular to a device for machine tool bearing rings. Background Art

[0002] The machine tool bearing ring is an annular zero of a radial rolling bearing with one or more raceways. The bearing ring includes an inner ring and an outer ring. Its processing steps are: cutting - grinding - heat treatment - fine grinding of the end face - fine grinding of the outer circle (inner hole) - fine grinding of the groove - fine grinding of the groove. It can be processed and manufactured with high nitrogen stainless steel, standard bearing steel and ceramics. The parts equipped with bearings have low friction.

[0003] However, grinding is the last step in the processing of bearing rings, and the requirements for the precision, surface roughness and quality of bearings are very high.
