ABSTRACT:
A method for electroerosive machining of metal workpieces and related apparatus. The erosion head of an electroerosive machining apparatus is moved with a blank clamped in it to a machining device for machining the blank with a machine tool held in the machining device, preferably a rotating milling tool the erosin head, and moves the blank for machining relative to machine tool as directed by a control computer. The machining device is located below the erosion head, with a vertical or horizontal axis of rotation, the electrode, following its manufacture, form the blank, is moved while still held by the erosion head to the electroerosive machining apparatus. Alternatively, an additional clamping device can be provided constructed like the erosion head for holding an electrode blank for machining by the machining device, while a workpiece is machined by electroerosion using an electrode held by the erosion head.
