<p><P>PROBLEM TO BE SOLVED: To provide a sheet polishing machine capable of preventing any over-polished state at a peripheral edge of a color filter 1 even when surface wear occurs in a polishing head 40, and the supply of polishing liquid is excessively large in both ends. <P>SOLUTION: In the sheet polishing machine for executing the polishing by pressing a rectangular polishing head against an upper surface of a color filter and revolving the polishing head while horizontally conveying the color filter, a plurality of polishing liquid dripping nozzles 11 are provided in the width direction orthogonal to the advancing direction. Each polishing liquid dripping nozzle drips polishing liquid of arbitrary concentration. Each polishing liquid dripping nozzle has each tube pump 50 and each polishing liquid tank. Each polishing liquid dripping nozzle drips the polishing liquid of an arbitrary concentration and an arbitrary amount. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
