By permanently comparing the machine load-ing, grinding can be made more efficient and simultaneously safer. If the load increases, the feed will be decelerated accordingly. If the load decreases, the speed is increased accordingly. With AC grinding, alternating loads on the grind-ing wheels will be prevented by a continual load.
