EDM GRAPHITE BLOCK
EDM graphite blocksare becoming more and more popular among our customers. EDM graphite is a new material. In recent years, with the development of China's industry, remarkable achievements have been made in science and technology. It has become the theme of The Times to create higher quality and lower cost in the field of precision mold industry. Therefore, graphite blocks for machininghas become a new vane to look for newer graphite block material to replace copper electrodes in the industry. Therefore, the demand for EDM graphite blocks from our company is increasing in many EDM graphite suppliers.
EDM GRAPHITE BLOCKS TECHNOLOGY
EDM graphite, now more and more widely used in precision mold processing industry, more than 90% of the mold processing electrode material is graphite. Copper, once the dominant electrode material, has almost lost its advantage over graphite.
Why is that? Because of graphite materials for EDM discharge has great advantage, because the spark oil also contains C atoms, in electro discharge machining, the C atoms are in high temperature makes the spark oil decomposition, thus the surface of the graphite rod electrodes in EDM form a protective film, compensate the loss of graphite electrode, prolong the service life of the graphite electrode.
EDM GRAPHITE BLOCKS ADVANTAGES
01
Faster processing speed. Under normal circumstances, the mechanical processing speed of the high-purity graphite product can be 2-5 times faster than copper, and the discharge speed is 3-5 times faster than copper.
02
The material is less prone to deformation and has obvious advantages in the processing of thin reinforcement materials.
03
Lighter weight. The density of graphite is only 1/5 of copper, which can effectively reduce the burden of machine tools (EDM) when large electrodes are used for discharge machining.
04
Less discharge consumption. Because spark oil also contains C atoms, during discharge machining, C atoms in spark oil are decomposed by high temperature, which in turn forms a protective film on the surface of graphite electrode to compensate the loss of graphite electrode.
