ABSTRACT:
A centerless grinding machine of tangential feed type including a work holder which is divided into a workrest for holding a workpiece as well as for loading and unloading same to and from grinding position, and a workrest holder for supporting the workrest during grinding operation as well as for giving depth of cut to the workpiece. The workrest and the workrest holder are reciprocatively moved by their independent driving mechanisms and adapted to be combined for giving depth of cut to the workpiece held in the workrest during grinding operation. Immediately upon completion of the grinding operation, the workrest is separated from the workrest holder and returned upwardly for unloading the workpiece from the grinding position. After the next workpiece to be ground is set in the workrest, the workrest is again moved into grinding position so that centerless grinding operation is carried out repeatedly, to thereby shorten the time necessary for loading and unloading the workpiece to and from the grinding position as well as to present a fully automatic centerless grinder.
