[0038]

As will be understood from the above description of the embodiments of the present invention, according to the first aspect of the present invention, the work from which burrs are to be removed is placed on a work table and placed on a bed. On the other hand, move the worktable in the front-rear direction, move the moving body left and right with respect to the intermediate frame while rotating the polishing belt provided on the portal frame, and lower the pressing element provided on the moving body. By pressing the polishing belt to bring the polishing belt into contact with only the burrs generated on the work, the burrs can be removed and the polishing belt other than the burrs does not contact the surface of the work.

Since only the burrs are removed and the surface of the work is not damaged, the burrs generated on the work such as the surface-treated steel plate and the mirror material of SUS can be easily removed.

According to the second aspect of the present invention, the portal frame is moved in the front-rear direction with respect to the bed with the workpiece from which burrs are to be removed placed on the work table, and the polishing provided on the portal frame is performed. The moving body is moved in the left-right direction with respect to the intermediate frame while the belt is rotated, and furthermore, the pressing member provided on the moving body is moved down to press the polishing belt, thereby forming a polishing belt on the work. By contacting only the burrs, the burrs can be removed, and the polishing belt other than the burrs does not contact the surface of the work.

Since only the burrs are removed and the surface of the work is not damaged, burrs generated on the work such as a surface-treated steel plate or a mirror material of SUS can be easily removed.

According to the third aspect of the present invention, since the elastic body is provided between the moving body and the presser, the elastic body exhibits a floating function when the presser comes into contact with the burr of the work. Thus, it is possible to prevent the workpiece from being pressed by a moderate pressing force and pressed against the burr of the work with a strong pressing force.
