摘要： A device is disclosed for edge-machining an optical lens, clampable between two aligned holding shafts rotatable about the rotational axis of a workpiece, having a Z slide, which is guided longitudinally displaceably on a base frame in a Z direction parallel to the rotational axis of the workpiece, and an X slide bearing a tool post with an edge-machining tool, which is guided longitudinally displaceably on the Z slide in an X direction perpendicular to the Z direction in such a way that the edge-machining tool may be brought into machining engagement with the optical lens. For industrial use, the base frame is of substantially O-shaped construction and surrounds the Z slide, wherein the Z slide is likewise of substantially O-shaped construction and surrounds the X slide. In addition or as an alternative thereto, provision is made for an additional machining means to be fixed to the X slide, which means comprises at least one further edge-machining tool, which may be moved from a parked position into a machining position between the lens and the edge-machining tool on the tool post.

摘要： An apparatus is provided for securing and clamping optical lenses requiring edge-machining, in particular spectacle lenses, which exhibits improved handling and which is optimised from the point of view of virtually backlash-free rotary drive of the optical lens. Elements located between two holding shafts, in particular a clamping assembly, a securing member with securing member adapter and an adhesive connection between securing member and optical lens are specially designed for this purpose.

摘要： A very versatile device is proposed for high-precision machining of optical workpieces, in particular optical lenses, which comprises a horizontally displaceable gantry with at least one vertically displaceable tool spindle and a yoke with workpiece holding means mounted so as to be rotatable about a swivel axis by means of journals fitted on both sides. For swivelling of the yoke without gearing and therefore without backlash, a torque motor is provided concentrically to the swivel axis, which motor is directly connected actively with one of the journals.

摘要： A device for centering clamping of lenses, comprises two aligned centering spindles, arranged one above the other, with bell clamps. One centering spindle is guided axially in a centering spindle guide and may be moved relative to the other centering spindle by a lifting apparatus. To achieve a smooth, sensitively adjustable clamping movement with precise axial alignment of the centering spindles to allow clamping of small lenses, a swivellable rocking lever is provided, to which the mobile centering spindle and a counterweight are coupled on opposing sides. The lifting apparatus is provided with an electric motor-driven ball screw, which raises or lowers the mobile centering spindle and/or the centering spindle guide is equipped with linear guide units, which are arranged on each side of the mobile centering spindle in substantially play-free manner between the latter and a box-type structure.
