Technical field

The invention relates to the field of polishing, in particular to a shaft member polishing mechanism with high safety and a using method thereof.

Background technique

Polishing and grinding is often required in applications where the dimensional accuracy of shaft parts is high. In order to achieve the required size, dimensional processing and surface smoothing processing can be performed while grinding and polishing. This often requires different polishing forces and rotational speeds. In order to carry out different polishing strategies according to different workpieces, it is often necessary to carry out different polishing processes according to different workpiece conditions. Especially in the case of manual polishing, such polishing processes that vary with different workpieces often involve relatively complex and numerous polishing equipment workstations. This poses a disadvantage to production costs and involves more complex workstation transfer steps or more complex control procedures.
