EDM graphite

Short Description:

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.

Technical Characteristic

Compared with copper, EDM graphite has the following advantages:

1.Machining speed: high speed rough milling is 3 times of copper block, and high speed fine milling is 5 times of copper block.
2.Good machinability, complex geometric molding is available.
3.Light weight, low density (less than 1/4 of copper), easy to clamp.
4.It can reduce the number of single electrodes, because it can be bundled into composite electrodes.
5.Good thermal stability and no deformation
6.No machined burr.

Jiangxi Ningheda New Material Co., Ltd. selects excellent graphite materials both at home and abroad. The graphite material has the characteristics of high purity, fine grain, good electric conductive and thermal conductivity, high density, corrosion resistance, good thermal resistance, good thermal stability, high mechanical strength, low permeability, good oxidation resistance and so on. And with a complete set of CNC machining equipment, the accuracy of graphite molds can be accurately controlled, which makes us meet customer needs all the time.
