摘要： PURPOSE:To provide threading on a target under a particular environment by making it possible to change, through the second motor's driving, an electric discharge-machining threaded electrode which moves vertically while swiveling by the first motor's driving. CONSTITUTION:When the first motor 8 is driven, the first gear 10, the third gear 15, shaft 17 and an electric discharge-machining electrode 20 rotate and go upward or downward respectively to approach a target for lower boring by lower electric discharge. After lower boring work, the electric discharge- machining electrode 20 is made to go upward completely and a sleeve 12 is rotated by driving the second motor 9 for rotating a planetary gear 18 and traveling itself. At this time, rotation is made in a cycloid curve since the axis of the planetary gear 18 is eccentric with that of a holder 16. Also, only when the electrode 20 is installed just above a target 1 with the rotation of the sleeve 12, the first gear 10 is engaged with the third gear 15, and the electrode 20 for boring is adjusted so that it may be changed to the one for threading in order. Therefore, only driving of the second motor 9 makes it possible to change the electrode 20.
