Erosion device for electric discharge machining (EDM) of objects e.g. erosion tools, has left drive and right drive that includes common drive motor, and are respectively integrated into casing of wire guide

摘要

The device has a wire electrode feeding apparatus (10) that comprises a left drive which is provided to supply an unused wire electrode to a processing zone (16) using a feeding-drive roller , and a right drive (13) which is provided to discharge a used wire electrode (14) to the processing zone using a feeding-drive roller (20). The left drive and the right drive having a common drive motor are respectively integrated into a casing (38) of a wire guide.
