Tungsten • Molybdenite wire
Sumiden
Be superior to an electric discharge characteristic , a high temperature strength characteristic,and the extra-fine electrode line of 20μm - 100μm that going straight on characteristics have good shows a superior characteristic in wire electric discharge machining. It is the best for the ultra-precision machining typified by metal mold for semiconductor lead frame and detailed part processing, and power is demonstrated to accuracy and a productivity drive.
