Graphite electrodes for the EDM machining

  • For its indisputable advantages, graphite is suitable for electrical discharge machining. In the form of electrodes, it is used for manufacturing of pressing components, mainly for consumer industry.
  • The strong points of graphite electrodes include relatively low weight, easier machining treatment,
    lower wear, high dimension stability, thermal capacity and higher removal rate.
  • Moreover, there is a possibility to glue graphite with two-second and conductive glues.

Weight of graphite is 5 times lowerr=1,80g/cm3(graphite) vs. r=8,93g/cm3(cooper)
Easier machining property Strengths at processing are 10 times lower in comparison with cast steel
Lower wear 1/3 to 1/10 of the figures for Cu
Low thermal expansionThermal expansivity 4 times lower than at Cu
High thermal loadSublimation point up to 3650°C
higher removal rate1,5 to 3 times higher than utilizing Cu electrodes
