[0002] A ceramic tip positioning structure can refer to a high-precision positioning structure used in ceramic materials. Ceramic materials have excellent wear resistance, high temperature resistance, corrosion resistance and other characteristics. Therefore, in some applications that require high-precision positioning, ceramic materials are often used as the materials for positioning structures. A common ceramic tip positioning structure is a ceramic ball tip structure. It consists of one or more ceramic balls and corresponding positioning grooves. The circular surface of the ceramic ball can provide a smaller contact area, thereby reducing friction and wear. The shape and size of the groove will match the diameter of the ceramic ball to ensure accurate positioning. This structure is commonly used in high-precision instruments, optical devices and various mechanical devices.
