CNC-bearbejdning af kobberelektrode

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.
Under EDM-bearbejdning, kobberelektroden og emnet er henholdsvis forbundet til de to poler af pulsstrømforsyningen. Pulsspændingen påført kobberelektroden og emnet genererer gnistuft. Den øjeblikkelige temperatur af udledningen kan være så høj som 10,000 grader celsius, og den høje temperatur gør overfladen af ​​emnet delvist fordampet eller smeltet.

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. Derfor, 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, stål, messing, cast iron, etc.
