METHOD FOR MANUFACTURING ROD-LIKE COMPONENT

摘要

A method for manufacturing a crankshaft with a turning and broaching machine is provided with a temporary setting process, a lifting process, a centering process, and a clamping process. An unprocessed crankshaft is mounted on first and second temporary settings in the temporary setting process. A rear flange is lifted by a first chuck jaws and a front flange is lifted by a second chuck jaws in the lifting process. First and second centers are inserted into first and second center holes in the centering process.

1. A method for manufacturing a rod-like component by machining a rod-like workpiece with a machine tool equipped with a first chuck device and a second chuck device, the first chuck device having a first temporary setting, a first center disposed higher than the first temporary setting, and a first chuck jaws, the second chuck device having a second temporary setting facing the first temporary setting, a second center facing the first center, and a second chuck jaws, the method comprising:
a temporary setting process for mounting a first temporary setting part of the workpiece on the first temporary setting and mounting a second temporary setting part of the workpiece on the second temporary setting; a lifting process for lifting the first temporary setting part with the first chuck jaws; a centering process for inserting the first center into a first center hole formed in a first end surface of the first temporary setting part and inserting the second center into a second center hole formed in a second end surface of the second temporary setting part; and a clamping process for clamping the first temporary setting part with the first chuck jaws and clamping the second temporary setting part with the second chuck jaws.
