  • EDM graphite

    EDM graphite

    EDM graphite, also known as graphite for electric discharge machining, is a new type of material, which is now more and more widely used in the precision mold processing industry. At present, in mold processing plants in developed European countries, more than 90% of mold processing electrode materials are graphite. Copper, once the dominant electrode material, has almost disappeared its advantages compared with graphite electrodes. Why is this so? Because graphite has a huge advantage as an electrical discharge material for EDM, since spark oil also contains C atoms, during electrical discharge machining, the high temperature causes the C atoms in the spark oil to be decomposed, thereby forming a protective film on the surface of the EDM graphite electrode , The loss of graphite electrode is compensated, so the loss of graphite electrode is very small, so the service life is long.
