EDM Graphite Electrode

EDM graphite has been used popularly in both HK and PRC recently, valued from their high cutting speed and machining performance. Of such a foreseeable trend in some high technology industrial countries like Europe and Japan, we have successfully introduced EDM Graphite to many mold makers and experts in HK for many years. It is believable that graphite electrodes promise to replace conventional copper electrodes.

•Easily machined into shape and hand-finished
•Light in weight (~ / 5 of Copper). Reduce the loading of EDM
•High electric discharge machining speed (1.5-3 times of copper)
•High density and low wearing rate
•Low thermal expansion (coefficient of thermal expansion ~ / 4 of copper), meaning that thermal deformation reduced
•Variety grades range from rough finishing, precision finishing to ultra precision finishing
