Description of the Related Art In the case of a cathode ray tube panel, it is press-molded into a predetermined shape by a molding die, then taken out of the die and sent to a polishing step. In the polishing step, for example, polishing is performed in the order of rough polishing, medium polishing, and finish polishing. A polishing tool and an abrasive used in each stage are suitable for each stage of polishing. In rough polishing, a large number of metal blocks having a polished surface are arranged at an appropriate distance from each other and fixed to a single thin metal plate, which is bonded and fixed to a metal support base via a buffer material, and this is then polished with a polishing tool. We use as.

る。In each of the metal blocks of the above-mentioned polishing tool, a metal round bar is cut into a short column shape, and one end surface is fixed to a thin metal plate as it is, and the other end surface is used as a polishing surface.
In addition, the periphery of the edge is used as a polishing edge. In this case, the polishing slurry is supplied from the center hole of the support base, the cushioning material, and the metal thin plate through the inside of the hollow rotary shaft that drives and rotates the support base, and flows on the polishing surface of the CRT panel (hereinafter simply referred to as the panel). It is spread over the entire polished surface by each flowing and rotating metal block. Then, free abrasive grains mixed in the polishing slurry are introduced between the end face of each metal block and the surface of the panel, and the surface of the panel is polished with the abrasive grains. The surface of the panel is polished with the edges and abrasive grains.

たため、研磨効率の向上が望めなかった。However, in the conventional polishing tool, the shape of the end face of each metal block, which serves to spread the polishing slurry over the entire polishing surface, remains a metal round bar, so that the free abrasive grains are removed from the end face of each metal block and the panel. Since the function to be introduced between the surface and the surface was poor and the effective polishing edge surface was small, improvement in polishing efficiency could not be expected.

When it reached the size, it came off freely and was mixed in the polishing slurry, causing the panel to be scratched (scratched).

Although the cushioning material is interposed between the supporting base and the thin metal plate, the deformation efficiency is poor and the adhesion to the curved panel surface is not good, so that the polishing efficiency cannot be improved.
