Non-standard bearing manufacturer to tell you a good bearing finishing order step rely on what source: bearing | last updated: - 2020 06 - 27 non-standard bearing manufacturer to tell you a good bearing finishing order steps depend on what a good bearing finishing order. 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. Non-standard bearing profile of non-standard bearing ( GB / T 276 - 1994). The original list of radial ball bearing is the most widely used rolling bearing. It is the feature of low friction resistance and high speed. It can be used to bear radial load at the same time or the radial and axial load of mechanical parts. It can also be used to carry axial load of mechanical parts, such as small power motor, automobile and tractor gearbox, machine tool gear box, general machinery, tools, etc.
