GRINDING DISK AND METHOD OF MANUFACTURING SUCH A DISK

摘要

TITLE OF THE INVENTION: GRINDING DISK AND METHOD OF MANUFACTURING SUCH A DISK A grinding disk with an interrupted,circumferentially contoured surface for sanding or polishing a respectively contoured work piece surface has a plurality of sectortype grinding disk elements secured to a hub for rotation with the hub. The disk elements are produced by first casting a straight longitudinal grinding body, which is then cut into said elements, which are secured to the hub with sector spaces between neighboring elements so that the circumference forms a polygon. Substantial savings are achieved because now the hub can be used repeatedly by merely replacing the worn-out grinding body made of the sector-type grinding disks.
