Since a reciprocating movement component is applied to the workpiece, a grinding direction component perpendicular to the running direction is generated in the grinding direction of the workpiece, which removes uneven polishing on the surface of the workpiece and makes the workpiece uniform and beautiful. It becomes possible to grind it. In addition, unlike the conventional structure in which an endless sanding belt is run at an angle, there are excellent effects such as no increase in the width of the belt and no increase in the size of the device.
