Form crush dressing of diamond grinding wheels ScienceDirect

The main characteristic of crushing is that the tool and the grinding wheel should have exactly the same circumferential speed, i.e. a speed ratio q d = 1. This will avoid a relative velocity between the two bodies, resulting in lower wear of the profiling tool .Contrary to profile crushing the crushing speed v sd in form crushing is about 10 times higher to create an acceptable profiling time.
