Description

Technical Field

[0001] The utility model relates to the technical field of electric spark punching machines, in particular to an angle adjustment structure of an electric spark punching machine. Background Art

[0002] The EDM perforator utilizes the rotation of the hollow tubular electrode during operation and the servo electronic control system to increase the processing speed and perform high-speed perforation processing by evenly wearing the electrode.

[0003] The high-pressure and high-speed working fluid is sent into the deep hole and small hole processing area through the tubular electrode to strengthen the discharge of the electro-eroded products. The traditional EDM EDM puncher can only adjust the X, Y, Z axis and the lateral axis rotation. When the workpiece needs to be processed with an inclined hole, the EDM puncher often cannot adapt well, resulting in a limited processing process. The workpiece needs to be fixed and clamped on the inclined surface. When processing multiple inclined holes, it is cumbersome to repeatedly store and retrieve the workpiece. For this reason, we propose an EDM puncher angle adjustment structure to solve the existing problems. Utility Model Content
