Precision EDM's requirements for the electrode

In the actual processing process, there are often a lot of work pieces scrapped. We all know that the EDM process is to copy the shape of the electrode to the workpiece. Therefore, the shape, size and surface finish of the electrode determine the shape, precision and roughness of the workpiece to a certain extent. Electrode material is a key problem in Precision EDM, so the quality of electrode must be guaranteed by precise manufacturing method. Here are some of Precision EDM's requirements for the electrode.genos1818

1.After processing, the electrode should not be treated manually, but refined and polished if necessary, which can avoid affecting the accuracy of the electrode and put forward high requirements for the process level of manufacturing electrode.

2.Red copper is the most used electrode material in the field of electrical processing, which can meet the requirements of high precision machining. However, in Precision EDM, in order to reduce the electrode loss, reduce the number of electrodes, improve the quality of the machined surface, and achieve high stability processing, Consideration should be given to expensive copper-tungsten alloy electrode materials.

3.Before the electrode is used for Precision EDM, the size and shape of the electrode should be measured in detail.

In actual production and processing, WEDM-LS workpiece is often scrapped due to the problem of disqualified electrode. Therefore, it is very important to grasp the manufacturing of electrode in Precision EDM machining.
