The connecting zone between each face and the cylindrical surface initially includes an edge. A cylindrical deburring tool is mounted on a tool support for pivotal movement orthogonal to the axis of the lens. Rotation of the deburring tool about its axis is prevented. The angle position of the deburring tool is adjustable. A spring urges the mounting to a rest position. A drive displaces the tool support.
