Grinding processes. Grinding is a process with numerous geometrically undefined cutting edges/abrasives, which are integrated in the grinding wheel. Grinding is a manufacturing technique for machining surfaces with abrasives. The rotating grinding wheel performs the cutting motion, while the feed motions are conducted by the grinding wheel or

Grinding can achieve higher precision than rolling. In actual production, it is difficult to reduce the temperature of the grinding zone during the inner hole grinding process. The high temperature of the grinding zone (the local temperature of the surface can be as high as 1000℃) will cause great harm to the service performance of the parts.
