Abstract:
PURPOSE: To make centering at recessing unneccessary by providing a first link rotated by a first eccentric shaft and a second link rotated by a second eccentric shaft.
CONSTITUTION: When a first eccentric shaft 12 attached to a shaft head portion 11 serving as a slide table and a second eccentric shaft 19 attached to a body 9 are put to their original positions, a feed unit (not shown) is advanced to cut holes by cutters 10. The shaft 17 is fixed and the shaft 12 is rotated 180° to displace the whole shaft head portion 11 in a parallel manner. Then, the shaft 12 is fixed and the shaft 17 is rotated 360°, so that the whole shaft head portion 11 is swingingly moved along the path of a circle of 2R, and then the recessing is finished.
