Abstract
A grinding machine comprising a truing apparatus for truing a grinding wheel made of cubic boron nitride. A traverse carriage of the truing apparatus is mounted for movement in a direction parallel to the axis of the grinding wheel. A truing head carrying a truing wheel is mounted on the traverse carriage for movement toward and away from the grinding surface of the grinding wheel. A detection member is mounted on the truing head to be movable toward the grinding wheel. The truing head is first fed toward the grinding wheel until the contact between the detection member and the grinding wheel is detected. The truing head is then fed toward the grinding wheel by a truing amount in response to the detection of the contact between the detection member and the grinding wheel.
