Bearing manufacturing general agent tell you bearing the processing sequence of steps correctly

Bearing manufacturing general agent tell you bearing the correct source of the processing sequence of steps: bearing | last updated: - 2020 07 - 01 bearing manufacturing general agent tell you bearing the correct processing steps good bearing finishing order sequence. Bearing the order of superfinishing usually can be divided into three steps: cutting, half cutting, finishing. Step 1: when the surface of the stone with a rough cutting good bearing raceway surface of the convex peak contact, because contact area is small, so the force per unit area of relatively large. Bearing artifacts 'reverse cutting' effect, leading to stone falling and cracking on the surface of some grits, thus reveal some new abrasive and sharp edge. At the same time, fast cutting Okey peak surface of the bearing parts, cutting and reverse the effect of cutting and by removing Okey bearing the workpiece and grinding metamorphic layer on the surface of the peak. This phase is called cutting stage, most of which metal balance has been removed. Step 2: Okey bearing half cutting with processing, gradually become smooth surface of the bearing parts. At this point, the surface of the grinding wheel and workpiece contact area increases, the pressure per unit area is reduced, cutting depth, cutting ability decline. At the same time, the grinding wheel surface holes blocked, grinding wheel in a state of half cut. The stage is called Oukai bearing half cutting stage of finishing. At half cutting stage, bearing cut marks on the surface of the workpiece more shallow, gloss and more dark. Step 3: complete phase it is Okay bearing super finishing the last step. As surface flattening, grinding wheel and workpiece surface to further increase the contact area, and the surface of the grinding wheel and the bearing of the workpiece is lubrication film gradually separate, small pressure per unit area, reduce the cutting effect. Automatic stop cutting. This phase is called complete phase. In the finishing stage, the workpiece surface cutting marks, no Oukai bearing shows bright gloss finish. It is divided into dimensional accuracy and precision rotating precision of the bearing, precision level can be divided into five levels: P0, P5, P6, P2 and P4, P0 level from the beginning. Will P0 bearings for special purposes will be enough. For some specific condition or situation, must use the P5 or higher precision bearing. The size of the bearing accuracy related to the installation of the shaft and bearing seat, usually refers to 1. Bearing inside diameter, outside diameter, width and the allowable deviation of the width of the assembly; 2. Chamfer size allowed limit; 3. Allow the width of the change. The rotating precision of bearing and the bearing of the rotator: 1, allowing the inner ring and outer ring along the radial and axial running; 2. Inner ring allows transverse beat; 3. Allow the change of outside diameter surface of slope.
