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 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.

摘要： A tool drive unit for a turning device for machining workpieces has a tool holder driven in a displaceable manner along an infeed direction by a first linear motor and driven in a pendular/displaceable manner in a direction transverse to the infeed direction by a second linear motor. Both linear motors have a moving coil/piezo element. The turning device has a main infeed drive, which produces a primary infeed movement of a turning tool in an infeed direction, and has a main transverse drive which produces a primary transverse movement in a transverse direction transversely to the infeed direction. The turning device has a secondary transverse drive whose movements are oriented in the same direction as the main transverse drive, wherein the turning tool and the axis of rotation can be moved towards one another and away from one another by the superimposition of primary and secondary transverse movements.
