Bearing steel balls is through the special steel mill production out, mainly through the following procedure:

1, the embryo: with all sorts of technology method and create all kinds of ball blank.

2., grinding: a ball into the blank with blank dimensions matching, up and down two with the same size of one word more ring, and section for the triangle groove of micropipette grinding, add oil, crude abrasive; On turning millstone, fixed chute. Above the grinding ball coarse grinding machine says. According to the needs, coarse grinding can have many way.

3, cleaning: every complete a coarse grinding, all will stick in the surface of the ball and thick abrasive residual oil wash.

4, fine grinding: will complete the coarse grinding blank into fine grinding machine; Add in low viscosity oil and fine abrasive, ground to a standard size;

5, polishing: process and coarse grinding, fine grinding similar.

And then after heat treatment, some have shot peening treatment, some are not. Last procedure is polishing, generally uses the grinding and polishing from the combination, so bearing steel balls is produced.
