GRINDING APPARATUS FOR FLAT PANEL FOR CATHODE RAY TUBE

摘要

PURPOSE: A grinding apparatus for flat panel for cathode ray tube is provided to maintain light intensity and luminance stable, lengthen useful life of the panel, while reducing manufacturing cost. CONSTITUTION: A grinding apparatus comprises a rotatable wear table(43) where a flat panel(10) to be ground is mounted; an adsorption head(50) including a spindle(52) arranged to be elevatable and rotatable along the axial direction of the wear table, and an adsorption member(53) coupled beneath the spindle in such a manner that the adsorption member is eccentrically movable with respect to the spindle and adsorbs the flat panel; and a luminance control pad(60) coupled to the wear table in such a manner that the luminance control panel is attachable/detachable to/from the wear table. The luminance control panel is formed of a non-woven fabric material and contacts and grinds the flat panel so that the flat panel has a predetermined luminance and light intensity.
