[0002] Machining refers to the process of changing the size or performance of a workpiece through a mechanical device. In many cases, the surface of the workpiece after machining often cannot directly meet the use requirements. At this time, grinding and polishing processes are required. Grinding and polishing belong to the category of precision and ultra-precision machining. It is mainly for further processing of the workpiece surface after machining.

[0003] In the existing grinding and polishing machine, the worker first places the fixed block on the grinding disc, then places the workpiece fixture into the fixed block and presses the pressing block, and the grinding disc is driven by the motor to rotate to grind and polish the workpiece;

[0004] Existing grinding and polishing machines of this type need to be constantly stopped to replace the workpiece fixtures when grinding and polishing different workpieces. This process is rather cumbersome and may occupy a large proportion of the entire processing cycle. For this reason, we propose a grinding and polishing machine. Utility Model Content
