    Abstract: The apparatus of this disclosure is for advancing the grinding wheel axially for grinding the radial surface of a workpiece. The actual advance of the wheel is caused by a piston and cylinder combination, wherein the piston is connected to the wheel mounting and the cylinder is free to move in the direction opposite to that of the piston except for a restraining force imposed by a spring. The movement of the piston is stopped by the engagement of the grinding wheel with the work with fluid under pressure causing the cylinder to move against the action of the spring. The movement of the cylinder provides a signal which cuts off the supply of fluid under pressure to the cylinder and the cylinder is locked against further movement. At the same time, the metering device is actuated which directs a predetermined volume of fluid to the cylinder. The piston advances the grinding wheel in accordance with this predetermined volume of fluid under pressure to advance the wheel against the work by a predetermined amount for a predetermined depth of cut on the workpiece.
