[0002] In modern precision machining and surface treatment processes, C-axis rotation mechanisms are widely used, especially in automated polishing, grinding, drilling and other processes. Existing C-axis rotation mechanisms are usually driven by a motor connected to a reducer, but the existence of the reducer limits the rotation speed and cannot meet the process requirements of efficient polishing. In addition, the existing C-axis rotation mechanism is easily contaminated by polishing fluid, dust and water vapor when rotating at high speeds, affecting the stability of the internal bearings, resulting in a shortened life of the mechanism and reduced machining accuracy. Therefore, there is a great need for a high-speed C-axis rotation mechanism that does not rely on a reducer and has a waterproof and airtight function to increase the rotation speed and meet the needs of precision machining.
