The wire erosion is a technology for the processing of electro conductive materials and metals. The processes are known as wire cut EDM, wire electrical discharge machining, wire EDM, wire cutting, EDM cutting, spark erosion or die sinking.
We can generally describe the wire erosion as a metal working process in which the desired shape is obtained using electrical discharges or sparks. It is used for the processing of materials with a higher degree of hardness and of the more sensitive materials. When other procedures are not suitable and electrically conductive materials are present, we choose this method. It is also used to achieve extremely complex shapes where the traditional machining techniques would damage the surface of the product. In addition to bringing many advantages, this process is also environmentally friendly and economical, as it does not consume a lot of energy.
The classic EDM (Electrical discharge machining) differs from the wire erosion in that it uses a tool for the electric current dispersion. A cathode flows along the metal and an electric current vaporizes or melts it.
