PURPOSE: An apparatus for polishing the panel of a cathode-ray tube is provided to uniformly maintain the contact pressure of a polishing tool over the entire effective area of the panel, to uniformly polish the effective area and to remarkably reduce loss of power. CONSTITUTION: An apparatus for polishing the panel of a cathode-ray tube has a support(12) and a rotatable ware table(22), located on the support, on which a panel to be polished is mounted. The apparatus further includes a spindle(24) placed on the ware table, being ascendable and descendable having the same axis as the rotation axis of the ware table, a polishing tool(26) located below the spindle to polish the effective area(11) of the panel(10), and a driver(28) for driving the spindle to allow the polishing tool to come into contact with the effective area of the panel.
