Bearing Superfinishing Process Stage

Bearing as the main parts of a variety of mechanical operation, in order to make the bearing in the use of better performance quality, the bearing in the processing process of ultra-finish machining technology, the so-called precision machining process refers to the processing accuracy and surface smoothness is higher than each phase.
The main four stages
(1) Intense cutting stage.When the surface of the workpiece is rough and the peak is in contact with the surface of the oilstone, the contact stress is very large, so that the abrasive particles are broken and self-sharpening, and the cutting effect is strong.
(2)Normal cutting stage.A few seconds later, the rough layer of the workpiece is removed, that is, into the normal cutting stage, there is no black chip adhesion on the surface of the stone, but the cutting continues.

(3) The grinding transition stage.The abrasive particles are reduced, the edge edge of the abrasive particles is flattened, and the chip oxide begins to embed into the gap of the oilstone. The abrasive powder blocks the pores of the oilstone, so that the abrasive particles can only be weakly cut, accompanied by extrusion and polishing. At this time, the surface roughness of the workpiece is quickly reduced, and the surface of the oilstone is attached by black chip oxide.
(4) Stop the cutting and grinding stage.The friction between the oil stone and the workpiece is very smooth, the contact area is greatly increased, the pressure drops, the abrasive particles can not penetrate the oil film and the workpiece contact, when the oil film pressure on the supporting surface and the oil stone pressure balance, the oil stone is floating.During the formation of oil film, then no cutting effect.This stage is specific to superfinishing.
