[0002] In CNC milling or CNC turning, when processing the shape and size of graphite electrodes, it is usually necessary to clamp the electrodes on a workpiece fixture or a specially designed fixture. Some electrodes with graphite ring shapes usually refer to annular parts made of graphite materials.

CNC machine tools are used for precision processing, usually including turning, milling, drilling and other processes to process graphite materials into corresponding annular parts.

At this time, the inner ring of the graphite ring can be processed by processing equipment. By arranging multiple graphite rings, multiple graphite rings can be processed in sequence. However, if some graphite rings have processing errors, it is easy to affect the clamping effect, thereby affecting the processing of the graphite ring. Utility Model Content
