Compared to traditional copper electrode, EDM used graphite material of Toyo Tanso has the following advantages:
1. Lower material cost:graphite price is 50% that of the copper electrode of the same volume;
2. Faster process speed:speed of the machinework is 2 -3 times that of the copper electrode without any burr appearing after the processing;Speed of the electro-discharge machining is 34%-200% faster than that of the copper electrode machining;
3. Less loss:spark oil decomposed carbonization is covered and the compensation electrode is consumed;
4. Lighter weight:density of the graphite is only 1/5 that of the copper, therefore the graphite is more suitable for the discharging of large electrode;
5. Difficult to deform:compared to the copper electrode, the graphite has the melting point up to 3650℃ without any deformation under high temperature, which is more suitable for processing the bone position electrode;

6. There has no burr after the machinework easy to polish. It dispenses with and enhances the auxiliary process;
7. Agglomerability:broken graphite can be bond with the binding agent to save the time and the material cost.

Just because of all these advantages and the high performance/price ratio of Toyo Tanso products, Toyo Tanso EDM has his graphite more and more accepted and recognized by Chinese dying enterprises, and finally become the partner of Toyo Tanso.
