The bearing grinding characteristics: the smaller vertical grinding allowance (0.20 ~ 0.60ram) feed amount (f_ vertical = 0.08B ~ 0.15Bmm / r), in time vertical pass rubbed off. This grinding method, grinding wheel dressing with the front the cone part or stepped in order to gradually cutting margin, or cutting work is mainly concentrated on the outside corner of the grinding wheel, make the grinding wheel exterior angle quickly blunting affect the grinding efficiency and surface quality.
    We must pay attention to dressing stepped wheel: the fine grinding repair light role from the largest cylindrical surface, the fine should be trimmed some of the rest of the stepped surface since kibble role should trim rough; close to the workpiece outer layer step height should be made larger, close to the finished surface of the step height made smaller. Thus, in order to obtain a high productivity, while at the same time guarantee that the surface roughness value is small. Grinding allowance the 0.60mm, grinding depth of 0.30mm. Kibble with coarse trimmed grinding wheel, the bearing Jingmo fine trimmed grinding wheel, in order to improve production efficiency.
    In the entire chain of wheel dressing is more complex, and the structure of the workpiece must allow wheel beyond both ends of the machined surface a greater distance, so is only applicable to a large number, a large number of production grinding structure to comply with the above requirements of certain parts. Some factory test proved the productivity of such a grinding method than the vertical mill method about can be increased about twice, sufficient accuracy can be obtained at the same time and a smaller surface roughness.
