Graphite electrodes for 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.
| ADVANTAGES OF GRAPHITE ELECTRODES | |
|---|---|
| Weight of graphite is 5 times lower | r=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 expansion | Thermal expansivity 4 times lower than at Cu |
| High thermal load | Sublimation point up to 3650°C |
| higher removal rate | 1,5 to 3 times higher than utilizing Cu electrodes |
