Method and device for the electroerosive material machining of a workpiece

摘要

The invention relates to a method and a device for the electroerosive material machining of a workpiece (3) by means of a longish electrode tool (1). The electrode tool (1) is guided in an electrode guide (15) in which an oval cavity (15a) is embodied. The wire section (1a) in the cavity (15a) is exposed to a magnetic field (18) and can be laterally deviated. The lateral deviation is carried out by an axial movement of the wire section (1b) located in the region of the workpiece (3), in order to produce an optimum working gap between the workpiece (3) and the free end part (1c) of the wire section (1e).
