A brief analysis of the characteristics of EDM

With the development of industrial production and the progress of science and technology, there are many new materials with high melting point, high hardness, high strength, high brittleness, high viscosity and high purity. More and more workpieces with various complex structures and special process requirements，this makes traditional machining methods impossible or difficult to process. Therefore, in addition to the further development and improvement of machining methods, people also strive to seek new processing methods. EDM is a new technology which is completely different from mechanical machining. It can meet the needs of production development and show a lot of excellent performance in application. Therefore, it has been rapidly developed and increasingly widely used. At the same time, we should also understand the characteristics of EDM.genos1818

The following is a brief analysis of the characteristics of EDM:
1.The pulse discharge has high energy density, is not affected by the hardness of the material, and is not affected by the heat treatment condition.
2.The duration of pulse discharge is very short, the heat conduction and diffusion range of discharge is small, and the influence of heat on material is small.
3.When machining, the tool electrode does not contact with the workpiece material, and the macroscopic force between the two is very small. The tool electrode material does not need to be harder than the workpiece material. Therefore, the tool electrode is easily made.
4.Can reform the structure of the workpiece, simplify the processing technology, improve the service life of the workpiece, reduce the labor intensity of workers.
The above is the characteristics of EDM, is a great progress in the development of science and technology, but also the gospel of workers, I believe that the future of China's EDM process industry will be better and better!genos1818
