A method for manufacturing a crankshaft with a turning and broaching machine (1) is provided with a temporary setting process, a lifting process, a centering process, and a clamping process. An unprocessed crankshaft (W) is mounted on first and second temporary settings (32d, 42d) in the temporary setting process. A rear flange (210) is lifted by a first chuck jaws (32b) and a front flange (220) is lifted by a second chuck jaws (42b) in the lifting process. First and second centers (32c, 42c) are inserted into first and second center holes (210CH, 220CH) in the centering process. |
