PURPOSE: A device for polishing a pot lid is provided to prevent the formation of a gap when a ring is matched to the end of glass by angularly processing the end of the round glass and to lengthen the life of a polishing wheel. CONSTITUTION: A pot lid polishing device comprises: a rotating part(40) horizontally rotating a round glass pane; a first polishing part(50) inclined to the rotational center of the rotating part for angular polishing of the upper and lower corners of the rotating glass(G); and a second polishing part(60) formed opposite to the first polishing part for vertical polishing of the side of the glass. If the glass is rotated while polishing wheels(57,59) of the first polishing part and a vertical polishing wheel(63) of the second polishing part are adhered to both sides of the glass, the first and second polishing wheels polish the upper and lower ends of the glass in 45 angular degrees. The vertical polishing wheel vertically polish the side end of the glass by rotating in an opposite direction to the glass. According to the angular shape of the glass end, a ring is firmly combined with the end of the glass without a gap. Using three polishing wheels, a process time is reduced and abrasion of diamond of the polishing wheel is restrained.
