<p>In an electric discharge machine and a machining method therefor according to the invention, an electrode (21) and an electrode guide holder (25) are attached to an electrode holder (23) in advance, and the electrode holder (23) is mounted on a main shaft (13), whereupon a grip arm (29) is caused to grip the electrode guide holder (25) and move the electrode guide holder (25) to the front end of the electrode (21). With an electrode guide (61) supporting the front end of the electrode (21), machining is performed. In such electric discharge machine and machining method therefor, when the electrode is consumed in fine hole electric discharge machining, requiring electrode displacement, the electrode displacement operation can be performed in a short time and reliably.</p> |
