Working principle of Wire EDM Tooling

Wire EDM tooling is a unique processing technology in industrial production. Unlike traditional processing technology that requires mechanical energy to cut, this technology uses the heat generated by the discharge of electric sparks to cut and remove the material. Therefore, EDM wire cutting technology is not limited by the material. You can process any conductive nature of the metal material, so wire cutting technology in industrial production and machining occupies a critical position.

The working principle of wire EDM tooling is separating metal materials by melting them after the heat generated by an electric spark's discharge reaches the metal material's melting point.

Wire EDM Tooling is divided into slow-wire, fast-wire, and medium-wire cutting according to the technology. In wire EDM, the difficulty of the processed workpiece material is not related to the hardness of the processed material because there is no significant physical or mechanical cutting force during the cutting process. This technology makes it possible to process all materials that can conduct electricity, such as alloys with high hardness.

However, there is a limit to the minimum corner radius of the workpiece to be machined. In Wire EDM Tooling, the minimum radius is the radius of the electrode wire plus the clearance between the workpiece and the operating table. In the actual processing, the shape of the wire EDM tooling is formed by the table moving according to the control program, which can only process the contour of the workpiece, and the remaining material can be used as usual.

Wire EDM Tooling is a conductive, excellent mobile metal to serve as electrodes; new electrode wire can be continuously replaced by new; in the processing area by the loss of metal electrode wire, the processing of workpiece spark discharge cutting forms a process method, so that the mobile electrode wire to avoid the loss of electrodes on the impact of processing accuracy. And Wire EDM Tooling technology is currently only in the through-hole and processing edge to cut in various complex parts perforated.

In the era of development of wire cutting technology, social development, and scientific and technological progress, wire cutting in various fields has also been very widely promoted. All these products are used in the application of wire cutting, so Wire EDM Tooling is the essential link in the socialization of the relevant industries in mass production. Nowadays, Wire EDM Tooling has been a very long development.
