Even though the soft-free cutting grinding wheel wear rapidly than a hard one, soft-free cutting grinding wheel is preferred for tool grinding. In long running the soft-free cutting grinding wheel economical because it reduces the injury of the tool due to overheating while grinding. The overheating problem also eliminated by reducing the grinding wheel rotating speed. The application of coolant and the type of coolant is depended on the material of the tool and type of grinding (soft grinding, rough grinding).
