A rotational automatic polishing device for a glass lens is provided to mount eight lens holders on a rotary arm provided at its upper portion and install a lens material supply and discharge unit provided at the lower portion of the apparatus, so that a spherical surface of a lens material is automatically produced by using a single device. A main shaft(22) having a plurality of arms(21,21') is inserted into the center of a fame(F). The frame is provided at a low end thereof with casters(11,11') and stoppers(12,12'). The frame is provided at an upper portion thereof with a bed(13). A driven pulley(23) is driven by a driving pulley(24) of a rotational motor(M) provided inside the frame. The arms have vacuum suction ports(25,25'). The arms are provided at the side surface thereof with lens holders(H,H'). The lens holders move left or right by cylinders. |
