APPARATUS FOR POLISHING PANEL FOR USE IN CATHODE RAY TUBE

摘要

PURPOSE: An apparatus for polishing a panel for use in a cathode ray tube is provided to prevent the increase of polishing time due to the degradation of operating rate of a spindle by improving the elevation structure of the spindle. CONSTITUTION: A spindle is installed on an upper portion of a ware table(62) so as to rise and fall. A polishing tool(58) is arranged on a lower portion of the spindle to polish a panel(10). A guiding unit(47) is formed on an end of an arm(40) adjacent to the spindle. An end of a slider is coupled to the guiding unit(47) so as to rise and fall and the other end thereof is coupled to the spindle to be risen and fallen together with the spindle. An actuator(90) makes the rising and falling of the slider. A spindle housing(80) surrounds the outside of the spindle. The slider is coupled to the spindle housing(80).
