Bearing steel ball through specialized steel ball mill produced, primarily through the following processes:
1, the system embryo: various process methods to produce a variety of spherical rough.
2, grinding: the spherical blank into the blank dimensions match, up and down two with the same size as the multi-channel concentric ring, the cross-section of the triangle grinding disc slot, add oil, coarse abrasive; on the disc rotates, The disc does not move. Above grinding ball machine that rough mill. Needed, coarse how Road.
3, cleaning: Each time a coarse grinding, you want to stick to the ball surface of the oil and coarse abrasive residual wash.
, Fine grinding: completed and coarse rough into fine grinding machine; adding low viscosity oil and fine abrasive, grinding to a standard size;
5, Polish: process and coarse grinding, fine grinding similar.
And then heat treated, some of the shot peening, and some is not. The last step is polishing, is generally used honing plus the combination of the polishing liquid, so that the steel ball bearings manufactured.
