[0053] At the same time, the air after automatic settling is discharged from the discharge pipe 22 and is finally filtered through the filter bag 26 to prevent metal dust from entering the air.

[0054] When in use, the rotating frame is controlled to rotate by the driving module, and the steel to be polished is inserted into the polishing box, and each polishing module is ensured to fit the surface of the steel to be polished. During the rotation of the rotating frame, the polishing module is driven to rotate, thereby realizing the polishing operation of the steel; during the polishing process, the steel to be polished is continuously pushed or pulled outward in the axial direction to realize the polishing operation of the entire outer surface of the steel; the polished metal powder enters the dust collecting box under the extraction of the negative pressure fan, and the air is discharged after filtering;
