摘要： A polishing device for polishing curved lens faces of optical lenses has a workpiece holder for receiving an optical lens and a polishing tool. The polishing tool has a support element, an elastic substructure and a curved polishing surface on the elastic substructure. The polishing tool, with the polishing surface, is driven in a rotating manner about a rotation axis, the workpiece holder being driven in a rotating manner about a first axis, in order to rotate the optical lens. A distance between the workpiece holder and the polishing tool is adjustable along a second axis. An offset between the workpiece holder and the polishing device is adjustable along a third axis, which is aligned transversely in relation to the first axis. A pitch angle between the rotation axis and the first axis is adjustable by tilting about a fourth axis. A method of operating the device is also disclosed.

摘要： An optical lens blank includes a first and a second lens surface, which are arranged opposite each other and which are delimited at a lens circumference, wherein the first lens surface has a surface geometry that corresponds to a first partial cutout from a first melon shape. A range of blanks consisting of such lens blanks have first lens surfaces of varying degrees of curvature, wherein the different degrees of curvature are based on different melon shapes. Finally, a method for producing a spectacle lens from such an optical lens blank includes mechanically shaping at least the first or second surface, and separating a cutout from the mechanically shaped lens blank.

摘要： A turning device has two turning stations, each with a rotatable work piece spindle to hold a lens blank, each lens blank with a turning tool for the machining of a lens blank. A method for the operation of the turning device, wherein first and the second lens blanks are simultaneously machined with the turning tools is disclosed. Control electronics attune drive signals to each other such that certain drive signals for fast tool servomotors of the turning tools accomplish at least a temporary or phase-wise opposite running of the fast tool servomotors for vibration dampening. A fabrication mechanism is provided for the manufacturing of eyeglass lenses from lens blanks with a milling device and a turning device along with a method for operating the fabrication mechanism.

摘要： A polishing method for machining an optical surface of an optical lens uses a polishing wheel which has a wheel axis and a polishing face. The polishing wheel is moved in relation to the lens over the surface of the latter along a spiral machining path. The polishing wheel is rotated about the wheel axis, and is (simultaneously) rotated about an axis of rotation oriented perpendicularly to the wheel axis. The rotational speed of the polishing wheel about the wheel axis and/or the axis of rotation is reduced at the spiral center of the movement path. A workpiece fixture for receiving an optical lens stands opposite the polishing wheel, with the workpiece fixture and the polishing wheel being mounted movably in relation to one another along a spiral movement path. The rotational speed of the wheel axis can be coupled kinematically to the rotational speed of the axis of rotation.

摘要： A blocking piece for vacuum blocking a lens blank is disclosed. The blocking piece includes a blank contacting element formed of a rigid fluid-permeable material having an upper surface for contacting the lens blank. The blocking piece further includes a support element having an upper part tightly enclosing the blank contacting element on a peripheral surface of the blank contacting element and a lower part adapted to engage with a clamping device for clamping the blocking piece. The lens blank is fixed to the upper surface of the blank contacting element by applying a vacuum within the blocking piece to provide suction through essentially the entire upper surface of the blank contacting element. The disclosure further relates to a method for blocking a lens blank and a use of an element formed of a rigid fluid-permeable material as a part of a blocking piece.
