The application discloses a
metal polishing device, and belongs to the technical field of
metal polishing, which is used for
polishing the side edges of a workpiece in two
modes of feeding the workpiece in the direction of a polishing belt and sliding the workpiece transversely, and comprises a belt polishing
assembly and a multifunctional operation table fixedly installed with the belt polishing
assembly. The multifunctional operation table is used for assisting the workpiece to slide in the direction of the belt polishing
assembly or transversely, specifically, an operator can push the workpiece in the direction of the polishing belt of the belt polishing assembly, and the frame is fed in the direction of the polishing belt of the belt polishing assembly together with the workpiece to complete polishing; another mode is that the frame is moved close to the polishing belt of the belt polishing assembly, the limiting blocks are located on both sides of the polishing belt of the belt polishing assembly, the workpiece is slid transversely under the guidance of the roller, and the polishing belt of the belt polishing assembly is limited by the limiting blocks, so that the polishing belt of the belt polishing assembly is not fallen off in the working process.
