Edm Graphite Electrode High Precision (Electric Discharge Machining)

We manufacture, export and distribute, EDM Graphite Electrode High Precision (Electric Discharge Machining) in Tianjin, Tianjin, China.

Characters:
1. High accuracy, stable quality, long service life, and high strength lower cost compare with copper electrodes(decreased about 25-30%).
2. Low coefficient of thermal expansion
3. Special treatment of anti-oxidation dramatically increase service life span at least 2 times more than common anti-oxidation treatment. (national PATENT)
4. High thermal stability for strict working conditions(dramatic performance of anti-shock-chilling)
5. Low ash content.
6. Anti-acid and alkali resistant, high chemical stability, prolong service life
7. Anti-stain, high purity and density.
8. ISO-9001:2000 TUV & SGS testing report can be provided according to customera s requirements

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.
