Turning The Large Steel Ball
Generally the larger diameter of the steel ball, because its rough is heated forming forging method, it has the larger volume. Thus, after annealing it can be grinding by ball turning lathe, and then proceed to flashing, hard-grinding and fine grinding processing. The purpose of turning is removed the rings, the polarization and the processing remaining.
The left volume of steel ball will increase with the diameter. Rely on flashing grinding, hard-grinding or fine grinding processing to remove the volume is non-economic, it should process by lathe. The excess part of steel ball will be removed increasing with the diameter. Ball universal lathe can be modified, as long as the change into a special seat and high speed turret gear.
