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.
Während der Erodierbearbeitung, Die Kupferelektrode und das Werkstück sind jeweils an die beiden Pole der Impulsstromversorgung angeschlossen. Die an der Kupferelektrode und am Werkstück anliegende Impulsspannung erzeugt eine Funkenentladung. Die momentane Temperatur der Entladung kann bis zu hoch sein 10,000 Grad Celsius, und die hohe Temperatur führt dazu, dass die Oberfläche des Werkstücks teilweise verdampft oder geschmolzen wird.
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. daher, 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, Stahl, Messing, Gusseisen, usw.
