| 摘要 |
The present invention relates to an electric discharge machine and a method for carrying out the electric discharge machining in the electric discharge machine in which, after an electrode (21) and an electrode guide holder (25) are attached to an electrode holder (23), in advance, which is in turn mounted on a spindle (13), the electrode guide holder (25) is gripped by a gripper arm (29) and moved to a distal end of the electrode (21) so that the machining is carried out while the distal end of the electrode (21) being supported by an electrode guide (61). When the electrode must be replaced due to the exhaustion thereof during the electric discharge machining of a fine hole, the above electric discharge machine and method make it possible to assuredly carry out the replacement of the electrode in a short time. |
