Power Metal Group uses non-resistance and anti-electrolysis power supply. It has the functions of water immersion machining and taper cutting. The practical maximum processing efficiency is 120-150 mm2/min. The best surface roughness is ra < 0.5μm. The cutting accuracy can reach ±0.005mm。 It can be used in all kinds of mold processing, precision components, c-axis processing and medical supplies processing.
