Classification, uses and manufacturers of graphite electrodes
Graphite as electrode(1) the processing speed is faster: normally, the mechanical processing speed of graphite can be 2~5 times faster than copper, while the discharge processing speed is 2~3 times faster than copper;More material is not easily deformed: obvious advantages in the processing of thin electrodes; copper softening point at about 1000 degrees, easily deformed by heat; graphite sublimation temperature is 3650 degrees; the thermal expansion coefficient of copper is only 1/30.(2) lighter weight: the density of graphite is only 1/5 of copper. When large electrode is used for discharge machining, it can effectively reduce the burden of machine tools (EDM). It is more suitable for large-scale die applications.
The difference between graphite electrodesMainly from the current, density, resistance, bending strength, ash parameters are measured
Classification of graphite electrodes:(1) common power graphite electrode (RP), (2) high power graphite electrode (HP), (3) quasi ultra high power graphite electrode (SHP), (4) ultra high power graphite electrode (UHP) Note: poly carbon classification method
