Erosion cutting machine for cutting closed concave or convex forms (15; 16) from a work piece (12) fixed to a support; to that effect, a wire or band electrode (14) is used, which is fixed to guiding means (13, 18). At least one guiding means (13, 18) is arranged on a rotary motor device (20), so that the center line (23) of the rotary device (20) is in register, at least on one geometric location, with the center of the section of electrode (14). Thereby, a collision of the guiding means (13, 18) with the forms (15, 16) or even with a support (11) is avoided during the erosion process. |
