Product Description

Compared with Traditional Copper Electrode for EDM Industry

  1. Production Cost: Cost of isostatic graphite is 25% lower compared with the same volume of copper electrodes.
  2. .Easy to process: the machining speed is 3-5 tims faster than copper electrode’s, and the surface is smooth. Electric Discharge processing speed is 1/3 -2times faster than the copper electrode’s, and specially for rough machining.
  3. Machining Accuracy: good machining precision, and the C.T.E is 1/4 of copper’s.
  4. Low Weight: the density of graphite is only 1/5 of copper’s, it’s more suitable to produce larger electrode to make giant parts.

About processing and production

With high performance of Numerical Control Machining Center Lathe any size special shape can be processed according to drawing, and a diversity of high quality material available.
