Description

Technical Field

[0001] The utility model relates to the technical field of abrasive belt grinding equipment, in particular to a bezel abrasive belt grinding equipment. Background Art

[0002] After the bezel is produced, its surface needs to be polished. The surface of the bezel of this design is a multi-segment inclined structure, which is difficult to polish with previous polishing equipment. In addition, previous polishing equipment usually uses a sanding belt transmission device to control the sanding belt transmission to achieve polishing of the workpiece.
