LOW FORCE WIRE GUIDE FOR EDM MACHINE A wire guide directs a wire electrode from a refeed mechanism in an electrical discharge machine EDM to a workpiece. The wire guide has a tension cap and a fixed wire guide body ceramic insert defining a precision guide slot for the electrode and wherein the tension cap is biased by a flex ring mounted on separated ends of the tension cap and body to retain them together. The biased tension cap has tapered surfaces at its exit end which produce a compound tension force on the electrode for maintaining a low friction force thereon during the life of the wire guide. |
