<p>The contact lens fabrication tool operates by removal of material, and has spindle (15) holding a contact lens blank (16). A controllable cutting tool (6) can be displaced relative to the contact lens blank. The cutting tool is mounted on a lever (4) which can rotate about an axis of rotation (7). The lever is controlled by an electric motor with a coil (10) acting on a magnet (9) so that a controlled displacement can be produced between the coil and the magnet. The displacement also controls the position of the cutting tool, as either the coil or the magnet is attached to the lever.</p> |
