A workpiece holder for a vertical broaching machine for broaching annular workpieces is provided with at least two centering pieces for radial immobilization of the workpieces. The centering pieces are radially pressable against an annular surface of the workpiece by a common drive means. The centering pieces are displaced until they rest firmly against the radial surface of the workpiece, thus ensuring that diametrical tolerances of the workpiece are completely eliminated. |
