As we all know, the use of a variety of graphite. In the 1960s, copper is widely used as an electrode material, usage accounting Jiucheng, graphite is only about one percent; Qingdao graphite 21st century, more and more users are choosing graphite as electrode material, high carbon graphite in Europe, more than 90% of the electrode material is graphite. Lacey graphite copper prices, which once dominated the electrode material, and graphite electrodes almost disappeared compared to its advantage. What are the advantages of graphite in the end actually become progressively replaced the copper EDM electrode material of choice it? Discharge consumes less; the spark oil also contains C atoms, in the electric discharge machining, high temperatures cause sparks and oil C atoms are unpacked, instead on the surface of a graphite electrode protective film is formed, instead of loss of graphite electrodes. No glitches; copper electrode processing is completed, the need to be trimmed by hand to remove the burr, but after graphite machining burrs, significant cost savings, but also easy to automate production; graphite easier grinding and polishing; the cutting resistance of graphite Only one fifth of copper, it is easier for manual grinding and polishing; lower material costs, prices are more stable; copper prices in recent years, and now the price is lower than the isotropic graphite copper, the same volume, Japan universality of carbon graphite products prices lower than the price of copper - Liucheng three percent, and prices are more stable, short-term price fluctuations are very small.
