Characteristics of Graphite Electrode materials
1. Fast speed;
2-3 times faster than copper, Graphite discharge data is not easy to deformation, on the thin steel electrode processing advantage significantly, at the mercy of the softening point of copper in 1000 degrees, simple occur because of the heat deformation, raise the temperature of 3650 degrees at the mercy of graphite, in comparison, as long as the copper graphite material thermal expansion coefficient of 1/30;
2. Light weight;
The density of graphite is only 1/5 of the copper, and the large electrode can be used to discharge the machine (EDM), which is more suitable for the use of large molds.
3. Small loss;
Because the spark oil contains C atoms, in edm, high temperature cause the C atoms are broken down in the spark oil, the surface of graphite electrode and in form protective film, compensate the loss of graphite electrode;
Copper electrode at the end of the process, still need to craft to remove burrs, and graphite electrode after treatment no burr, this not only saves a lot of money and manpower, more simple complete automation production together;
5. Easy polishing;
Because graphite's cutting resistance is only 1/5 of the copper material, it is easier to grind and polish the craft.
6. The money is low;
Because copper prices have been rising in recent years, now, the price of each side is lower than that of copper. In the same volume, the universality of dongying carbon, the price of graphite is 30 to 60 percent lower than copper, the quotation is stable, and the short - term quotation is relatively small.
