(Effects of the Invention) As described above, according to the present invention, it is possible to cope with a change in the twist direction of the tooth hills simply by raising and lowering the indexing unit, and the work is easy. The number of movable axes of the spindle can be reduced without increasing the number of movable axes of the indexing unit, the tool life and machining accuracy can be improved, and the indexing unit can be easily replaced. Has the effect of increasing further.
