EDM Speed Of Graphite Material

Graphite is a non-metallic material with a very high melting point and can withstand greater current setting conditions. When the discharge area and the size of the electrode are enlarged, the superiority of high-efficiency rough machining of graphite materials becomes more significant. The thermal conductivity of graphite is 1/3 of that of copper. The thermal energy generated during the discharge process can be more effectively used to remove metal materials. Therefore, its processing efficiency is also higher than that of copper electrodes in medium and fine processing. According to processing experience, under the correct conditions of use, the discharge processing speed of graphite electrodes is 1.5 to 2 times faster than the overall copper electrode.
