Abstract

A cylindrical grinder for simultaneously effecting stock removal from a plurality of work diameters of a rotating driven workpiece comprising a grinding wheel assembly including a plurality of grinding wheels, means for advancing the grinding wheels toward the workpiece from a predetermined first position to a predetermined second position at a selected feed rate, a workrest assembly operatively associated with a central work diameter including upper and lower workrest jaws, and means for incrementally displacing said upper workrest jaw towards the central diameter, means for sensing the magnitude of the non-linearity of the workpiece, and means for conjointly deenergizing the incrementally displacing means when the magnitude of the non-linearity sensed by the sensing means exceeds a predetermined maximum value.
