3M6312研磨机使用的滚子研磨轮是滚子生产的专用工具。一般情况下研磨滚子1万9千粒后,研磨轮即报废。其主要原因是挡边磨损。挡边磨损后根部形成塌角,破坏滚子球基面的几何精度和外观质量。 为了增加研磨轮挡边的硬度和耐磨性,我们在挡边工作面上进行火焰淬火。作法是将研磨轮夹持在车床上或可旋转的工具上匀 The roller grinding wheel used on the 3M6312 grinding machine is a special tool for roller production. Under normal circumstances grinding roller 19,000, the grinding wheel that scrapped. The main reason is that the ribs wear. After the wear of the ribs, the roots form a collapsed corner, which destroys the geometric accuracy and appearance quality of the roller ball base. In order to increase the hardness and wear resistance of the rim of the grinding wheel, we flame-quenched the face of the flange. The practice is to clamp the grinding wheel on a lathe or a rotatable tool
