SKF bearing the super finishing order is generally can be divided into three steps: cutting, cutting, light the whole half finishing.
The first step: SKF bearing cutting

Millstone surface and rough groove surface convex peak in contact, because the contact area is lesser, the more stress on unit area, in certain pressure effect, but the first being a SKF bearing the workpiece "against cutting" effect, make millstone surface part of the grits and chipped off, exposing some new sharp grits and edge. At the same time, the surface of the workpiece SKF bearing by convex peak fast cutting, by cutting and the cutting role SKF bearing on the surface to remove the convex peak and grinding badness layer. This phase is called cutting stage at this stage, removed the most of the metal residue.

The second step: cutting the half SKF bearing

With the processing to continue, SKF bearing surface of workpiece gradually be ground ping. At this time, and the surface of the contact area increased, unit area in the pressure drops, cutting depth decreases, and cutting decreased ability. At the same time, the surface of the porosity blockage of stone, stone cutting state in half. This phase is called the cutting precision bearing SKF half stage, the half cutting stage SKF bearing the surface traces cutting becomes shallow, and appear darker luster.

Third step: the light the whole stages

This is the super finishing SKF bearing the last step. As the surface was gradually to wear away, millstone and the surface contact area further increases, and, with the surface of workpiece is gradually SKF bearing the oil film of isolation, the pressure on unit area is very small, cutting function decreases, and the last to be automatic stop cutting. This one phase we call light the whole stages. Light the whole stages the surface no cut trace, SKF bearing appears bright finished product luster.
