ABSTRACT:
A grinding machine, having a wheel carrier with a rotatable cubic boron nitride grinding wheel mounted on a bed. The wheel carrier is slidable with respect to a work support device and a truing device, which are selectively opposed to the grinding wheel through movement of a traverse table. Feed and feed control devices are provided to feed the wheel carrier from a transient original position to an advanced position in a grinding operation. A detecting device is further provided to detect an absolute original position of the wheel carrier. The feed control device is arranged such that, whenever a truing instruction is supplied, the wheel carrier is retracted to the absoluted original position and then, is advanced therefrom to a truing position incremented by a predetermined truing infeed amount from the advanced position.
