IKO bearing manufacturing process of the deep grinding

The IKO bearing grinding method is characterized by: all grinding allowance ( 0．20～0．60ram) With small vertical feeding ( 15 BMM/r) In a longitudinal feed mill. Using this method of grinding, needs to have before the grinding wheel dressing into cone section ( Figure 7 - 5a) Or step ( Figure 7 - 5b) , so that gradually cutting allowance, or cutting work mainly focused on the grinding wheel on the exterior Angle of the grinding wheel outside, quickly become dull, affect the grinding efficiency and surface quality. Finishing step grinding wheel should pay attention to: the biggest plays a role of fine grinding and repair the light cylindrical surface, so should be fine, a modification to the rest of the stepped surface coarse grinding effect, should trim some coarse; In addition, close to the steps of the workpiece outer height should be larger, and close to finishing the surface of the bench height smaller. So, to achieve high productivity, at the same time to ensure that the surface roughness value is small. Figure 7 - 30 mm. Adopting such IKO bearing grinding method, due to travel less and grinding wheel using reasonable ( Coarse grinding with rough dressing of grinding wheel, IKO bearings with fine dressing of fine grinding wheel) , so can improve the efficiency of production. But dressing grinding wheel is more complex, and the structure of the workpiece must be machined surface can let the grinding wheel is beyond the distance at both ends, so only applies to a lot of, a large number of grinding structure meet above requirement of some of the parts in production. Some factory test show that the grinding method of productivity than longitudinal grinding about can be doubled, and can obtain enough accuracy and low surface roughness.
