Makino’s (Mason, OH) EDGE2 Sinker EDM machine with fine-hole option using a 0.00024 inch diameter silver tungsten electrode cut a communications/fiber optic part to a 0.00044 inch finished hole diameter. Other specifications of this achievement include a hole diameter held to +/- 0.00005 inches with positioning pitch location accuracy of +/- 0.0005 inches. Positioning pitch between holes was 0.004 inches. Workpiece thickness at hole location was 0.0010 inches. This machine provides consistent hole size and location to within .002mm repeatability. Automatic Electrode Dressing Technology creates ultra precision electrode diameters as small as 0.0002 inches. Key technology also includes high accuracy, high-speed spindle and precision positioning accuracy. The ultra precision discharge circuit for micro machining also contributed. Automated Electrode Changing and electrode handling mechanism ensure maximum unattended operation.
