Abstract
A wire guide apparatus for an electrical discharge machine (EDM). A movable feeder is placed in contact with a wire electrode, so as to transmit a machining voltage thereto. A workpiece is machined to a desired shape by virtue of electrical discharge between the wire electrode and the workpiece. An eccentric die is moved in cooperation with the feeder so as to change a contact position between the wire electrode and the feeder. Accordingly, the feeder wears more evenly and the life thereof is increased.
