8 common misunderstandings in precision mold processing
We know that EDM is the electrolytic erosion of workpieces, while electrochemistry is the use of electrolyte to dissolve the workpieces. Relatively speaking, EDM is now very popular. For example, in precision mould manufacturing, EDM is an important art. However, some technical misunderstandings in the mold factory will cause the CNC EDM to fail to meet the expected accuracy, surface, and efficiency requirements. Let's analyze and explain these common problems. 1. When the electrode hits the workpiece to be centered, it often misses The method of using the electrode to directly touch the workpiece belongs to surface contact. There are inevitably more or less fine objects between the contact surfaces, and there are also clamping accuracy errors on the contact surfaces, which will directly affect the accuracy of edge finding and centering. With this method, the contact surface must be strictly required to be wiped clean, but due to the presence of human factors, the accuracy will be
