EDM Graphite Electrode

Compared with the copper electrode,EDM graphite electrode has more advantages:lower producing cost,faster producing speed,easier to be polished,lighter weight,less consumption and high temperature resistance.

Advantage of EDM graphite electrode
1. Faster producing speed: In general, the speed of the graphite machining is 2-5 times faster than the copper, and the discharge machining speed is 2-3 times faster .
2. Deformation resistance: Advantage is obvious in producing thin layer electrode.The softening point of the copper is around 1000 ℃, thus the copper is easy to be deformed due to heat.However, the sublimation temperature of the graphite is high to 3650 ℃ and the thermal expansivity is only 1/30 of the copper.
3. Lighter weight: The density of the graphite is only 1/5 of the copper, the burden of the machine can be effectively reduced when using the large EDM electrode.It is more suitable for large model making.
4. Less consumption: When EDM, the C atoms in the spark oil will be released and stick to the surface of the graphite electrode to form a protective slick in high temperature,which compensates the consumption of the graphite electrode.
