Description

Technical Field

[0002] With the development of industrial production and the progress of science and technology, new materials with high melting point, high hardness, high strength, high brittleness, high viscosity and high purity continue to emerge, and there are more and more workpieces with various complex structures and special process requirements, which makes traditional mechanical processing methods impossible or difficult to process. Therefore, in addition to further developing and improving mechanical processing methods, people also strive to find new processing methods. Electric spark machining can adapt to the needs of production development and shows many excellent properties in application.

[0003] Electrospark machining (EDM) is a method of machining a workpiece by electro-erosion caused by pulse discharge between the tool electrode and the workpiece electrode in a certain medium. The pulse discharge energy density of EDM is high, making it easy to machine special materials and workpieces with complex shapes that are difficult or impossible to machine using conventional machining methods. It is not affected by the hardness of the material or the heat treatment condition.

[0004] When processing complex curved surfaces, specific tooling may be required to fix the angle of the workpiece to facilitate the electrode to process the processing position. However, the angles of the curved surfaces at different positions of the workpiece may require different tooling to fix the corresponding processing angles, which results in high processing costs. Therefore, we propose equipment for EDM surface processing. Utility Model Content
