[0002] Metal processing is the production of materials with metallic properties that are made of metal elements or mainly composed of metal elements. It is a process technology that processes metal materials into objects, parts, and components, including large parts of bridges and ships, as well as small components of engines, jewelry, and watches. It is widely used in different fields such as science, industry, art, and handicrafts.

[0003] There are many processing equipments in the field of metal processing, including efficient circular centering devices for precision metal parts processing. The circular centering devices are mainly used to mark the center point of the circle, but most of the existing circular centering devices are three-axis settings. Although the three-axis setting can ensure the positioning of the center of the metal processing part to a certain extent, its stability needs to be improved, and the existing circular centering devices can only locate the center of the circle, so they cannot meet the centering needs of some specific workpieces.

[0004] To this end, we provide a high-efficiency circular centering device for precision metal parts processing to solve the above-mentioned problems. Utility Model Content
