Abstract
The machine includes: elements for supporting the lens and for driving it in rotation about a first axis of rotation, the rotation of the lens being driven by first driver element, a tool-carrier mounted to turn about a second axis of rotation, turning of the tool-carrier being driven by second driver element, a plurality of working tools mounted on the tool-carrier to rotate about tool axes, with at least two of the tools including tools for shaping the periphery of the lens for shaping having distinct tool axes, third driver element for driving relative spacing movements between the first axis of rotation and the second axis of rotation, swivel elements for enabling the tool-carrier to be pivoted relative to the first axis of rotation about a third axis of rotation that extends substantially transversely to the first axis of rotation.
