  • the invention relates to a device for fine machining the optically effective surfaces of spectacle lenses, as in so-called "RX workshops", i. Production facilities for the production of individual spectacle lenses are widely used according to prescriptions.
  • the machining of the optically effective surfaces of spectacle lenses can be roughly subdivided into two processing phases, namely first the pre-processing of the optically effective surface to produce the recipe macrogeometry and then the fine processing of the optically effective surface to eliminate Vorbearbeitungsspuren and obtain the desired microgeometry.

  • a pivot drive By means of the pivot drive, the angular position between the axes of rotation of the tools and workpieces can be preset before the tools are lowered by means of the piston-cylinder assemblies on the workpieces.
  • the forming the preamble of claim 1 DE-A-102 50 856 discloses in this connection a polishing apparatus (see Figs Fig. 5 to 9 ) with a rotary electric drive for the polishing tool, which as such has a stator and a rotor, and with a pneumatic piston-cylinder unit for axial deflection of the polishing tool along a longitudinal axis.
  • the arrangement of the rotary and axial drives is made such that a rotatably mounted in a housing about a rotation axis spindle shaft assembly ("rotor" in the linguistic use of the above document), which at their extending from the housing end the actual polishing tool, is rotatably driven by a toothed belt drive of the electric rotary drive, which is laterally offset in the housing, arranged parallel to the axis of rotation; the pneumatic piston-cylinder unit and an associated axial guide, however, are integrated in the spindle shaft assembly, thus rotationally driven, which is why the piston-cylinder unit for supplying pressure medium requires a compressed air rotary feedthrough.
  • This polishing device has a relatively large space requirement, which is why it is not suitable for use in the above-described "twin" polishing machine.
  • a device for fine machining the optically active surfaces of particular spectacle lenses having a tool receiving portion having a spindle shaft which is rotatably mounted in a spindle housing about a tool axis of rotation, a rotor and a stator having electric rotary drive, by means of which with the Rotor operatively connected spindle shaft is rotatably driven about the tool rotation axis, and an adjusting device, by means of which the tool receiving portion with respect to the spindle housing in the direction of the tool rotation axis is axially displaceable.

  • the axial movement of the polishing tool should be as smooth as possible.
  • This property is particularly important for the polishing of spectacle lenses with toric, atoric or progressive surfaces with high deviation from the rotational symmetry, so that the polishing tool always full or flat and with sensitive adjustable polishing force (or contact force) rests on the lens. If, in fact, the polishing tool would lose the surface contact to the workpiece surface during its high-speed rotary motion only for a short time, the coarser grains and agglomerates present in the polishing agent could cause scratching of the polished spectacle lens surface.
  • the device according to the invention is eminently suitable for use in e.g. the above-described "twin" polishing machine, so that using other polishing methods with rotationally driven polishing tools, the processing times can be significantly reduced (ie, divisor 2), without increasing the low complexity of this polishing machine over charge or their space or space requirement at all to enlarge.

  • Such polishing plates 47 are for example the publication DE-A-10 2007 026 841 refer to; the interface 192 essentially corresponds to that in the DE-A-10 2009 036 981 illustrated and described interface. In this respect, reference should be made at this point to the cited documents.
  • gases such as e.g. Compressed air, or liquids, such as oil, are understood, which can be used as a pressure medium.
  • a special feature of this device is that rotor and stator and the spindle shaft are arranged coaxially in the spindle housing, which in turn is guided axially displaceably defined in a guide tube in the direction of the tool rotation axis, wherein the spindle shaft is formed as a hollow shaft, via which for receiving a tool receiving portion running a membrane chuck tool can be acted upon with a fluid, which in particular requires a very compact design and allows rapid axial compensating movements of the tool during fine machining.
