摘要

PROBLEM TO BE SOLVED: To enable automatic exchange an electrode guide for guiding and supporting a thin hole machining electrode as required. ;SOLUTION: When a small hole machining electrode 33 is exchanged, an electrode guide 39 mounted on a support arm 37 is unclamped, grasped by means of a hand 59 provided on exchange arm 57, moved together with the exchange arm 57 and maintained and received in the empty gripper 63 of an electrode guide automatic exchanger. Thereafter, the electrode guide 39 to be exchanged while being held and received in the indexed gripper 63 is grasped by the hand 59, moved together with the exchange arm 57 so as to be clamped in the support arm 37.;COPYRIGHT: (C)1997,JPO
