摘要： A device is disclosed for the surface machining of, among other things, plastic spectacle lenses, which has a work spindle, by means of which the spectacle lens can be driven with a controlled angle of rotation about an axis of work rotation, and a tool spindle, by means of which a tool can be driven to rotate about an axis of tool rotation, work and tool spindle being movable relative to one another with their positions controlled in two axes running at right angles. For rotational machining of the surface of the spectacle lens to be machined, the tool can also be swiveled by means of the tool spindle with a controlled angle of rotation about the axis of tool rotation, so that a rotational cutting edge provided on the tool can be brought into a defined rotational machining engagement with the surface of the spectacle lens to be machined as a function of the angle of rotation of the spectacle lens. Also included is a combined milling and rotational machining tool and a combined milling and rotational machining method. As a result, high cutting rates and very good surface qualities can be easily and efficiently achieved in the surface machining.

摘要： A process for edge-machining an optical (spectacle) lens including preliminary machining of an edge of the lens rotatable in controlled manner about a rotational axis of a workpiece by a first edge-machining tool adjustable radially relative to the rotational axis of the workpiece, whereby the lens is given a circumferential contour which corresponds to the circumferential contour of a lens holder apart from a slight degree of oversizing, contactless measurement of the preliminarily machined lens edge, and finish-machining of the lens edge, taking account of the detected edge data of the preliminarily machined lens, by means of a second edge-machining tool adjustable radially relative to the rotational axis of the workpiece, whereby the lens is provided with a circumferential contour substantially complementary to the circumferential contour of the lens holder. During preliminary machining of the lens edge, an edge surface which is definedly matt in the dry state is produced and then the dry or dried surface is measured by means of a measuring arrangement comprising a laser and a video camera and operating in a particular way without contact, in order to determine the edge data of the preliminarily machined lens with increased accuracy and markedly quicker than hitherto.

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.

摘要： In an initial stage the lens edge(R) is milled to a specific contour and in a final finishing stage the edge profile is completed and chamfers provided. Both initial milling and final finishing of the lens edge are effected with a combination tool(10) having milling cutters(26,28) and one or more rotating machining cutters(36). During the milling stage the tool is rotated around its axis(C) at a speed(nC) and prior to and during the machining stage makes a controlled angular rotation(psiC). Prior to initial milling and/or between this operation and the final finishing the lens radii and height values are measured and the latter are used in both milling and final finishing stages. In the finishing operation the combination tool(10), is rotated around its axis and moved radially relative to the lens rotation axis(B) so that the machining cutter(36) contacts the lens edge and the cutting face makes an angle with a tangent at the contact point. During machining of a non-circular lens the combination tool is rotated through an angle psiC = f (psiB, rB(approximatelyuB)) dependent on the lens rotation angle(psiB) and the lens radius(rB(approximatelyuB)) so that the angle between the tool cutting face and a tangent at the contact point remains constant. During final finishing an angled ridge with two flanks may be machined around the lens edge(R) by either: a) bevelled edges(32,34) at each end of the milling cutters(26,28); b) bevelled edges at each end of the machining cutter which cut each flank in turn; c) a V-shaped cut-out in the machining cutter. Alternatively a groove(N) may be cut around the lens edge by a cutting edge on the machining cutter. Chamfers may be produced between the lens edge and the optical faces(O1,O2) during final finishing using the bevelled edges at each end of the machining cutter. Edge polishing is effected by the machining cutter with a negative cutting angle. Independent claims are included for: a) the combination tool(10) which comprises a body(20) carrying milling cutters(26,28) and at least one axially displaced machining cutter(36) or alternatively milling cutters with a machining cutter at the same axial point between each milling cutter and offset radially inside the milling cutter cutting circle; b) lens edge machining equipment which includes lens holders(14,16) and a combination tool rotation spindle(12) with two linear movement directions(X,Z) and a controlled rotation through a specific angle(psiC) to enable a machining cutter to contact the lens edge at a desired point.

摘要： The invention relates to a device for loading and unloading optical workpieces, for an optical machine. The device comprises a loading arm (24) which is pivotally driven about an axis (A) and is pivoted in controlled movement sequences on the optical machine between a workpiece magazine (26, 28) and the operating position. The outer end of the loading arm is provided with a device (30) for receiving and placing workpieces. According to the invention, the swivelling axis of the loading arm is the central axis of a spindle (40) which rotates in both directions of rotation (D , X ) and which can be driven linearly in a lifting motion in both axial directions (X , X ) by means of drive elements, as well as guided in guide elements in a rotating and displacing manner. The loading arm (24) is fixed to the spindle.
