1. Center type grinding with axis feed: (Work spins slower) similar to cutting thread in the lathe. difference a shaped grinding wheel is used instead of the point cutting tool. (even multiple shaped grinding wheel can be used ). Speed –given by the RPM of the grinding. Several passes are necessary to complete the thread. 2.
All grinding wheels have a resistance threshold. If a grinding wheel shatters when rotating, the pieces that fly off can cause serious damage. Abrasives manufacturers therefore indicate on all their wheels both maximum peripheral speed and max-imum rotational speed. These must never be exceeded. peripheral speed (m/s)2 = wheel diameter x π x 60
