With certain combinations of electrode and workpiece material, under special operating conditions, "no-wear EDM" occurs, in which the wear ratio is 0.01. The most common combination for "no-wear" operation is a copper or graphite electrode and a steel workpiece. Materials: Any electrically conducting material, irrespective of hardness.

Most EDM electrodes are single-hole or multi-channel tubes. Both types allow for the flow of dielectric fluid, which aids in cooling and flushing. The choice between the two depends on whether through-holes or blind-holes are to be drilled. Both single-hole and multi-channel tubes can drill through-holes, though single-hole tubes are simpler to manufacture and thus cheaper.

24.02.2017When you grind it, it can clog up the grinding wheel – it heats up quickly and has a tendency to grab the grinding wheel. You'll have burrs no matter how you machine it, so you have to deburr it. Size and weight also can be an issue.

The most important limitation of copper as an electrode is its vulnerability towards the sparks generated during machining process. In comparison with graphite electrodes, copper electrodes last only half as much. Pure copper is highly malleable. This makes it difficult to be machined and it tends to clog the grinding wheel during manufacturing.
