銅電極のCNC加工

銅電極のCNC加工

The copper electrode of the EDM machine, Also known as CNC machining of copper electrode mirror. It is an indispensable part in the processing of EDM machine.
放電加工時, 銅電極とワークはそれぞれパルス電源の2極に接続されています. 銅電極とワークにパルス電圧を印加すると火花放電が発生します。. 放電の瞬間温度は次のように高くなることがあります。 10,000 摂氏, 高温により、ワークピースの表面が部分的に蒸発または溶解します。.

Immediately after the next pulse voltage, a spark discharge is generated between the copper electrode and the workpiece, and the above process is repeated.
Through countless repetitive pulse discharges, a shape corresponding to the shape of the electrode is finally processed. したがって, as long as the shape of the copper electrode is changed, various complicated profiles can be processed.
In EDM machining, the role of the copper electrode is to transmit processing pulses and to remove the workpiece with the minimum loss of the copper electrode itself. Commonly used electrode materials are copper, graphite, copper-tungsten alloy, silver-tungsten alloy, 鋼鉄, 真鍮, cast iron, 等.
