ABSTRACT:
When a face portion of a CRT glass panel is polished by fixing the glass panel on a rotating table and pushing a rotating cylindrical drum type polishing tool, which is supported by a supporting frame, to the face portion, the supporting frame is swung around a pivotal point so as to swing the polishing tool along an arc line on the face portion of the glass panel, and the polishing tool is moved reciprocately in a horizontal direction in association with an angle of rotation of the glass panel. Therefore, the face portion is polished while the distance between the rotation axis of the polishing tool and the center of the glass panel is changed. Since deflection of wearing of the polishing tool is decreased, the service life is prolonged, and further efficiency of polishing is improved.
