A method and apparatus are provided for effecting high production rate grinding of a plurality of workpieces on a grinding wheel rotating about an axis with reduced power consumption. Each workpiece is mounted in a holding fixture adjacent the grinding wheel to expose a face of the workpiece to be ground. The fixtures are positioned at spaced locations around the periphery of the grinding wheel whereby a grinding station is defined at each location. In one embodiment of the invention, one workpiece at a time is ground, but the grinding of a workpiece begins substantially simultaneously with the termination of the grinding of the preceding workpiece. The apparatus includes a vertically disposed grinding spindle with a grinding wheel mounted on the spindle driven by a motor which, along with the spindle, has a fixed location within the grinding machine housing. A removable upper spindle support member may be removably mounted to the housing above the grinding wheel.
