Abstract

A tool holder carries the grinding or polishing stone, and a transfer arm has suction pads and lens chucks which consist of scales (46) mounted with bearing cups on the spherical ends of shafts (47). The shafts are supported in bearing bushes so that they are free to rotate. The bearings in the bush are protected by a dust cap. The shape of the scale is so that it matches the shape of the lens to be machined. At least one 'O' ring is mounted in a groove in the top surface of the scale. The lens is placed on top of this 'O' ring. The space between lens 'O' ring and scale is connected via the hollow shaft to a vacuum source so that the lens is sucked agains the 'O' ring.
