SKF bearing finishing the order of the steps

SKF bearing superfinishing sequence generally can be divided into three steps: cutting, cutting, finishing finishing. First step: SKF bearing surface of the stone cutting and rough on the surface of the raceway convex peak in contact, because contact area is smaller, the force per unit area is larger, under certain pressure, the stone first by SKF bearing artifacts 'cutting' effect, make the part on the surface of the stone grinding grain fall off and broken, show some new sharp abrasive grain and the edge. At the same time, SKF bearing the workpiece surface convex peak fast cutting, cutting and cutting through the role of the removal of SKF bearing the workpiece and grinding metamorphic layer on the surface of the convex peak. This phase is called cutting stage, at this stage to remove most of the metal allowance. The second step: SKF bearing half cutting to continue with the processing, SKF bearing surface gradually be ground flat. At this point, the millstone and the surface contact area increases, the pressure on unit area is reduced, cutting depth, cutting ability. At the same time, the stone surface pores blocked, millstone is cutting state. This phase is called the SKF bearing finishing half cutting stage, SKF bearing surface cutting in half cutting phase trace becomes shallow, and a dark gloss. The third step: finishing stage this is SKF bearing super finishing the last step. As workpiece surface is smooth, millstone and further increase the contact area on the surface of the workpiece, and the stone and SKF bearing surface gradually be lubricating oil membrane separation, pressure on unit area is small, the cutting effect is reduced, the last stop cutting automatically. In this stage we call finishing stage. Surface finishing stage no cutting marks, SKF bearing present a light product luster.
