Abstract

A unit for form machining the edges of spectacle lenses, comprising a CNC-controlled machine tool for form machining of a spectacle lens, a determining device for determining lens parameters, or for attaching a block or a sucker in a correct position and at a correct angle, a lens conveyor past the unit, a manipulator for removing blank lenses from the conveying device, for inserting a blank lens into the determining device, for removing the blank lens from the determining device, for inserting the blank lens into the machine tool, for removing a finished-machined spectacle lens from the machine tool and for returning the spectacle to the conveyor, the manipulator having a transversely movable slides, slide having a first gripper for holding a blank lens and having a second gripper, movable independently of the first gripper, for holding a finished lens in the spectacle-lens edging machine. A method of operation of the foregoing is disclosed.
