Please senior doubts. The graphite electrode is used in the mold cavity In what case is graphite processing taken?
Instead of copper as discharge material.1. Electrode design1 can reduce the number of individual electrodes / can be made into a composite electrode2, it can save the electrode clamp system and save the cost2, the electrode processing1, high speed milling rough processing copper block 3 times2, high-speed milling finishing faster than copper 5 times3. Good machinability4, complex geometric modeling can be realized3, light weight, its density is less than 1/4 of copper1, good thermal stability (without deformation)2 can reduce the number of individual electrodes / can be made into a composite electrode3, without deburring4. The electrode is easy to clamp4 、 electric discharge machining EDM1, roughing, the electrode loss is small2, high work removal rate3 can reduce the number of individual electrodes / can be made into a composite electrode4. No pollution to the environment in the electrolyte5, light weight, its density is less than 1/4 of copper6, excellent thermal stability, the electrode does not change7, the fine graphite electrode can be used to produce high quality workpiece surfaceDifferent grades of graphite materials can be used for processing different workpieces
Graphite electrode has better machining stability and high production efficiency. It is easy to be used as EDM electrode material in EDM when it is processed with long pulse width and high current.
Because of the great loss of graphite electrode in finishing, it is not suitable to be used as finishing electrode material. Because of the small coefficient of thermal expansion of graphite, it can also be used as a big electrode material in perforation processing.
