Method and device for electroerosive material machining of a workpiece

摘要

A method and an apparatus for electroerosive material machining of a workpiece with an elongated tool electrode are described. The tool electrode is guided in an electrode guide, in which an oval void is embodied. The wire segment located in the void is exposed to a magnetic field, as a result of which the wire segment can be deflected laterally. The lateral deflection is converted into an axial motion of the wire segment located in the region of the workpiece, in order to create an optimal work gap between the workpiece and the free end part of the wire segment.
