EDM is a special processing method that uses the electro-erosion effect generated by the pulse discharge between the two poles immersed in the working fluid to remove conductive materials.
The basic way to achieve this processing is as follows: The tool electrode and the workpiece are all immersed in the working medium (electrolyte), multiple spark discharges are generated between the two electrodes, and the amount of workpiece erosion is consciously controlled, and finally the workpiece can be removed. Meet certain size and roughness requirements.

Due to the high discharge energy during electrical discharge machining, it can machine materials that cannot be machined by ordinary cutting methods, such as hardened steel, heat-resistant alloys, and cemented carbides. At the same time, it has been widely used in the processing of various complex cavities, dies, small and precise holes, narrow slits and other fields.
The specific application range is as follows:
1. All conductive materials can be processed by electrical discharge machining
2. The highest precision of electric discharge machining can reach +/- 0.005mm, and the surface roughness can reach the highest mirror surface
3. Stations that cannot be processed by traditional machining can generally be completed by electrical discharge machining
4. The discharge station can be the cavity of various large-scale plastic molds, or it can be a small hole with a width of 0.1MM, a small groove, etc.

EDM is the method of machining workpiece in a certain medium through electro-erosion effect of the pulse discharge between tool electrode and workpiece electrode. In this guide, we will take you through various elements surrounding HC EDM machining service as shown in the table below.
