Abstract
A wire guide directs a wire electrode from a refeed mechanism in an electrical discharge machine EDM to a workpiece. The wire guide has ceramic inserts defining a precision guide slot for the electrode and wherein one of the inserts is carried by a deflectable member spring biased to damp the electrode so as to maintain concentricity of holes formed by the electrode and thereby closely control the hole diameter.
