Bearing finishing the order of the steps

Bearing superfinishing order generally can be divided into three steps: cutting, cutting, finishing finishing. First step: the 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 'cutting' effect by bearing the workpiece, the part on the surface of the stone grinding grain fall off and broken, show some new sharp abrasive grain and the edge. Peak at the same time, the convex surface of the bearing parts are fast cutting, cutting and cutting through the role of the convex peak and remove bearing the workpiece surface grinding metamorphic layer. This phase is called cutting stage, at this stage to remove most of the metal allowance. The second step: bearing half cutting to continue with the processing, Carrie 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 bearing finishing half cutting stage, bearing the workpiece surface cutting in half cutting phase trace becomes shallow, and a dark gloss. The third step: finishing stage is this 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 is gradually lubricating oil film bearing surface segregation, the 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, bearing present a light product luster.
