The electronic sintered graphite mold requires high purity, the content of fixed carbon is more than 85%, and the content of harmful impurities is less than 1%. In recent years, high-speed milling has broken through the limitation that traditional milling is difficult to process high hardness, high strength and high toughness mold materials. However, EDM has high machining accuracy and surface quality, and can be processed in a wide range. Especially in the processing of mold cavities of complex, precise, thin-walled, narrow slit and high hard materials, its advantages are unmatched by high-speed milling. Therefore, EDM will still be the main means of mold cavity processing. Because graphite electrode (compared with copper) has advantages such as less electrode consumption, fast EDM speed, good machining performance, light weight and small thermal expansion coefficient, it has gradually replaced copper electrode and become the mainstream of EDM electrode. Compared with copper, graphite electrode has the advantages of less consumption, faster discharge speed, light weight and small thermal expansion coefficient, so it gradually replaces copper electrode and becomes the mainstream of EDM electrode.
