Polishing apparatus for a CRT glass panel and a method of polishing the glass panel

A method of polishing a CRT glass panel, the method comprising the steps of:

• fixedly mounting a CRT glass panel on a rotating table;
• rotating the rotating table;
• pushing a rotating cylindrical drum type polishing tool to a face portion of the glass panel to polish the face portion;
• swinging the polishing tool around a point on a linear line which is perpendicular to a rotational axis of the rotating polishing tool;
• and
• changing a distance between a central axis of the glass panel and a center axis of the polishing tool.

A method of polishing a CRT glass panel, the method comprising the steps of:

• fixedly mounting a CRT glass panel with a face portion to be polished directed upwardly on a rotating table;
• rotating a cylindrical drum type polishing tool around a center axis of the polishing tool;
• pushing the polishing tool to the face portion to polish the face portion;
• and
• changing a distance between a central axis of the glass panel and a rotational center axis of the polishing tool depending on an angle of rotation of the glass, panel;
• wherein said step of fixedly mounting the glass panel on the rotating table comprises the step of correlating the central axis of the glass panel with a rotational axis of the rotating table.
