ABSTRACT:
A drive wheel for rotating a workpiece while the latter is in contact with a grinding wheel during a grinding operation. The drive wheel is in the form of a pneumatic tire with a tire valve which permits easy variation of the internal pressure in the drive wheel. Thus the relative softness or hardness of the drive wheel can be changed in accordance with requirements attendant to the grinding operation. The drive wheel is motor-driven and a speed control device operates to slow the motor drive shaft when high torque loads are applied to the drive wheel by the workpiece, during heavy cutting of the workpiece by the grinding wheel. Thus the workpiece rotates slowly during heavy cutting and faster during light cutting.
