Abstract
A machine tool for cutting swarf entangled with a tool. A chuck is attached to a spindle of the machine tool, and grips a workpiece. The chuck is constituted by a first sub chuck and a second sub chuck detachably attached to the first sub chuck. The second sub chuck provided with a cutting tool is attached to the first sub chuck, and the cutting tool is caused to perform an opening/closing operation using a drive force of an opening/closing drive mechanism for gripping/releasing the workpiece, thereby cutting swarf entangled with a turning tool into fragments.
Claims16
A machine tool comprising:
- a rotating device for rotating a workpiece;
- a chuck provided at the rotating device and including an opening/closing drive mechanism for gripping and releasing the workpiece;
- a moving mechanism for adjusting a relative positional relationship between the workpiece and a turning tool for lathing the workpiece;
- and
- an attaching device for causing the opening/closing drive mechanism and a swarf cutting tool to engage with each other by attaching the swarf cutting tool to the chuck in a state where the workpiece is not gripped, and for cutting swarf entangled with the turning tool by driving the swarf cutting tool with an opening/closing operation of the opening/closing drive mechanism.
