EDM

　　EDM, as an industry with huge demand for isostatic graphite, is known for its demanding requirements for graphite materials, and has played a significant role in promoting the development of isostatic graphite technology worldwide for a long time.

　　Changrui graphite has the following advantages in the material application of EDM:

　　Better processing performance: tells that the rough machining speed is 2-3 times that of the copper electrode; the high-speed milling finishing speed is 5 times that of the copper electrode, and that there is no burr after processing and it is easy to polish.

　　Smaller loss: In EDM processing, basically no loss can be achieved.

　　Lighter weight: It is more suitable for the pole electrode of large electrodes, and graphite electrodes are easier to clamp.

　　Lower thermal expansion coefficient: A lower thermal expansion coefficient can ensure the stability of the electrode during processing.

　　Higher temperature resistance: The melting point of graphite is as high as 3850 ° C, which can withstand greater current.

　　Fewer electrodes: Fewer electrodes are required during processing, and less measurement work is required.
