The material of the fixing member 8A is, for example, synthetic resin such as polyacetal resin. Further, since the diameter D in FIG. 7A and the diameter d in FIG. 7A are set to be slightly larger than the workpiece 6, the cutout portion 7 and the groove width, after the fixing member 8A is press-fitted into the groove, vibration of the machine occurs. It does not come out of the groove to some extent.

For example, in the fixing member 8A shown in FIG. 7A, if the diameter d is larger than the diameter of the tool for cutting by about 0.1 to 0.15 mm, the fixing is easy. The taper at the tip of the fixing member 8A in FIG. 7A is for facilitating the insertion into the machining groove, and the length L is determined corresponding to the plate thickness of the workpiece.

According to the present invention, in the case of a large punching part,
The press-fitting points may be increased to such an extent that the work 6 and the cutout 7 are not separated by vibration. Further, when the number of headstocks 4 holding the spindle 5 is increased and the workpiece 6 is machined at several places, the fixing member inserter 8 can be attached to each axis.

[0018]
