Abstract

A grinding machine includes means for changing the feed rate of a grinding wheel relative to a workpiece when the grinding wheel approaches the workpiece. The grinding wheel is insulatedly mounted on a wheel slide which is moved by a feed device toward and away from the workpiece. An electrode device is mounted adjacent to the grinding wheel and is connected to an electric power source for generating a difference of potential between the grinding wheel and the workpiece. A detecting device detects the change of the difference of potential caused by the approach of the grinding wheel to the workpiece to generate a control signal. A control device controls the feed device so as to change the feed rate of the wheel slide in accordance with the control signal.
