Abstract
A wire guide for a servo driven wire electrode in an electrical discharge machine (EDM) has inserts defining a precision guide slot for the electrode. The inserts are coated with a low friction coating to smooth the servo drive of the wire electrode through the wire guide so as to improve spark gap erosion produced between a tip portion of the electrode and a workpiece.
