ABSTRACT:
Apparatus for finishing or polishing a surface of a lens with a finishing tool. The apparatus includes a main frame, a shaft pivotally mounted to the main frame, and eccentric drive means driving the shaft in a predetermined orbital motion. Lens finishing means are fixedly secured to one end of the shaft. A lens carrier is slidably mounted to the main frame such as to be reciprocable along a path perpendicular to the orbital axis of the shaft. The lens is removably mounted to the carrier and is biased by a biasing device against the lens finishing tool.
