PROBLEM TO BE SOLVED: To provide a machine tool that enables a workpiece to be attached without eccentricity to a jig and that makes a rotational balance of a product after cutting work better.SOLUTION: In a machine tool for cutting a workpiece, at least three holes are provided in a circumferential direction of a jig, near a location where the workpiece and the jig are brought into contact with each other when the workpiece is fixed, and air can be supplied from air supply means through the holes. Thus, since the workpiece is moved to the center of rotation, the workpiece can be attached without eccentricity to the center of rotation so that a rotational balance of a product after cutting work can become better. |
