The advantages of graphite materials

时时彩5星技巧 www.ugrvh.com   时时彩5星技巧Small make up to tell youThe advantages of graphite materials


  Speed is fast


  Graphite discharge 2-3 times faster than copper, the material is not easy to deformation, obvious advantages on thin steel electrode processing, the softening point of copper in 1000 degrees, easy to produce deformation because of the heat, the sublimation of graphite temperature of 3650 degrees or so, by contrast, only 1/30 of the copper graphite material coefficient of thermal expansion.



  Light weight


  The density of graphite is only 1/5 of copper, large electrode in EDM, can effectively reduce the burden of machine tools (EDM), the application of more suitable for large mould.


  Low loss


  Because the spark oil contains C atoms, in edm, high temperature lead to spark came out of the oil C atoms are broken down, and on the surface of graphite electrode form a protective film, compensate the loss of the graphite electrode.


  No burr


  Copper electrode at the end of the process, still need to manually remove the burr, the graphite processed without burr, this not only saves a lot of cost and manpower, but also easy to realize automatic production.


  Easy polishing


  Due to only 1/5 of the copper graphite cutting resistance, operation easier to grinding and polishing by hand.


  The cost is low


  Due to the copper price is rising in recent years, now, all aspects of gay graphite price is lower than that of copper; Under the same volume of graphite products price is thirty percent lower than the copper to 60, the price is stable, short-term price fluctuations was relatively small.
