ABSTRACT:
A spherical surface machining apparatus for machining optical lenses, mirrors and so on is provided which comprises a reference cam, mounted on a body frame located on one side of a grinding plate, a swing body movably mounted on the reference cam for supporting a lower shaft of the grinding plate and a driving cam follower mounted on the swing body and meshing with a rack formed on part of the periphery of the reference cam, wherein the lower shaft of the grinding plate is rotated, and the driving cam follower is driven to swing the swing body, to thereby make free the spherical center swinging trajectory of the lower shaft of the grinding plate. A container for accommodating an optical lens, mirror or the like is transported to a predetermined position by a reciprocally movable supply conveyer, and fixed or released by fixtures. Material for lens, mirror or the like, accommodated in the container is delivered to a grinding plate, ground thereby, and accommodated again in the container which in turn is transported by a transporting conveyer.
