PROBLEM TO BE SOLVED: To enhance the polishing efficiency by establishing a high speed rotation of a polishing head, increasing the pressure to the surface of a cathode-ray tube, and supplying a sufficient quantity of polishing liquid to between the head and the surface of cathode-ray tube. SOLUTION: A polishing head 21 is furnished with a polishing element 58 to polish the surface of a cathode-ray tube, and a torque given by a driving means is transmitted to the head 21 through a transmitting means 62. The transmitting means 62 is embodied on the gear coupling system to admit a high speed rotation and a high pressure and admit an inclination of polishing head 21 as tracing the surface configuration of the cathode-ray tube. Polishing liquid is supplied from the center of the polishing element 58. |
