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.
Durante el mecanizado por electroerosión, el electrodo de cobre y la pieza de trabajo están conectados respectivamente a los dos polos de la fuente de alimentación de pulso. El voltaje del pulso aplicado al electrodo de cobre y la pieza de trabajo genera una descarga de chispa.. La temperatura instantánea de la descarga puede ser tan alta como 10,000 grados Celsius, y la alta temperatura hace que la superficie de la pieza de trabajo se vaporice o derrita parcialmente.
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. Por lo tanto, 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, acero, latón, hierro fundido, etc..
