Mechanical electrode guide for electrical discharge machining

It is proposed an electric discharge machine (1) and an electrode guide (5) for an electrode (10) for electrical discharge machining of a workpiece (7), wherein three guiding elements (15a, 15b, 15c; 20a, 20b, 20c) for a precise guidance the electrode (10) are provided which are arranged rotationally symmetrical about the eletrode (10). The guide elements (15a, 15b, 15c; 20a, 20b, 20c), the shape of a sphere (15a, 15b, 15c) or a cylinder (20a, 20b, 20c) have. In the case of spherical guide elements (15a, 15b, 15c) can be positioned by the same setting pins (30), the variable lengths of the setting pins (30) are available.
