PURPOSE:To improve accuracy of thickness, yield rate and polishing efficiency, by spirally winding a metallic thin strip of amorphous material or the like on the peripheral surface of a cylindrical shaped roll to be polished by a rotary wheel. CONSTITUTION:An amorphous material 1 fixes its both end parts to the peripheral surface of a work winding shaft 2 so that winding force of the material may continually act through stop screws 3, 3' while a width end of the material may be brought into contact in a closely tight condition. And the work winding shaft 2, being rotated in a direction of rotation of an arrow head 8 in the drawing, that is, the winding direction of the amorphous material 1, prevents it from loosening. And the material 1 is polished by adapting a polishing wheel 10, while it is placed in a rotating condition, to the material 1 with a predetermined pressing load while laterally moving the whole shaft of the polishing wheel in the direction of an arrow head 17 in the drawing. In this way, the polishing method, in which the thickness of an adhesive layer as in the past can be almost neglected because the material 1 is mechanically wound on the work winding shaft 2, enables dimensional accuracy of thickness, yield rate and polishing efficiency to be improved.
