Definitions
- the invention relates to a polishing tool, in particular a ring-adaptive
- Polishing tool according to the preamble of patent claim 1, a method for
- Spectacle lens surfaces and mold shell surfaces in particular surfaces of spherical, toric and / or progressive spectacle lenses, according to the preamble of
- polishing tools are used with a spherically shaped polishing body according to the internally known state of the art, which adapts to the machined spectacle lens surface during polishing. So that the surface of the spherical polishing body can adapt to the geometry of the spectacle lens surface which is often very divergent from the spherical shape, an elastic foam material layer is adhered to a solid tool body. On this elastic layer, a polishing foil facing the workpiece is applied as a polishing pad.
- a polishing tool is e.g. in DE 10 2004 003 131 A I, DE 10 2008 062 097 A I or DE 603 12 475 T2.
- the polishing tools are generally smaller than the workpiece, as shown in Fig. 1 of EP 1 251 997 B2.
- the polishing removal comes with the aid of an abrasive polishing liquid through the
- the fundamental disadvantage of this arrangement is that the elastic layer of the spherical polishing tool, the height differences caused by the toric or free-form geometry of the spectacle lens has to compensate for the momentarily covered spectacle lens area completely. These height differences can be common with today, with toric Share equipped progressive lens surfaces may well be in the range of several millimeters. During the polishing process, the pressure distribution on the spectacle lens surface is therefore not constant. Because of the proportionality of locally applied polishing pressure and the resulting removal rate arise in this polishing basically form errors, the size of which depends on the extent of the asphericity of the spectacle lens.
- Tool diameter is chosen smaller with increasing deviation of the spectacle lens surface of the spherical shape. Because of the thereby reduced by the polishing tool covered and machined surface portion of the spectacle lens and also the generally reduced relative speed between the spectacle lens and polishing tool, the efficiency of the polishing process is significantly reduced.
- EP 1 249 307 A2 In order to be able to polish aspherical surfaces quickly and uniformly, EP 1 249 307 A2, with an otherwise identical structure, teaches the use of a toroidally shaped polishing body. Toric means barrel-shaped in this text.
- a method for producing aspherical surfaces of lens blanks, especially glass uses a CNC machine tool having a control unit and a rotatably deliverable pot tool for polishing a workpiece in a fixture that is movable along a feed axis to a machining position, the axes of pot tool and fixture forming an angle to one another.
- the pot tool is guided on the lens blank along a predetermined by the control unit machining contour such that between the longitudinal axis of the pot tool and the normal in its point of contact on the workpiece a selectable lead angle is maintained constant.
- the pot tool remains the same from the polishing point insert, during the entire machining with respect to the processing point on the workpiece aligned so that changing aspheres or ball radii are processed contoured in changing series. This is done with a constant same polishing diameter, so that the wear on the pot tool is minimized perpendicular to the contact surface.
- the pot tool comes because of the
- the lead angle is 0 °, from the starting position at the beginning of processing.
- the object of the invention is the generic polishing tool, the
- Eyeglass lens surfaces Casting lenses for eyeglass lens manufacturing with the features of claim 7 and by a device for polishing machining of
- the polishing tool according to the invention for surfaces of spectacle lenses or casting shells for spectacle lenses comprises a polishing lip with a rigid support, an elastic body arranged on the rigid support and a polishing covering arranged on the elastic body.
- the surface of the polishing pad provides a polishing surface. This polishing surface has at least one closed annular portion. Under closed
- Ring Toric section is understood to mean an annular (circumferential) segment of the shell of a ring torus, that is to say an annular partial surface of a ring torus surface.
- Such a polishing tool according to the invention may be similar to the pot polishing tool according to DE 44 12 370 AI formed and a polishing lip in the form of a Ringtorus Halbschale to have.
- the polishing lip of the polishing tool according to the invention additionally comprises, in addition to the rigid body functioning as a carrier according to the invention, an elastic body arranged on the carrier and one arranged on the elastic body
- the elasticity of the elastic body allows an adaptation of the polishing surface to the surface contour of the surface to be polished and thus a flat polishing removal, which according to the teaching of DE 44 12 370 A I just not desired.
- the DE 44 12 370 A I rather requires a punctual polishing removal.
- the closed annular portion of the polishing surface has a ring torus radius (main radius) and a lip radius (minor radius). It has proven to be beneficial
- Aspect ratio can on the one hand with the polishing tool a wide range
- the majority of common spectacle lens or G cumformschalenober vomgeometrien can be processed with polishing tools whose polishing surface has a closed ringtori see section whose aspect ratio is selected between 2.5 and 40.
- the number of tools required to polish the entire range of eyeglass lenses can be reduced.
- the aspect ratio has a value between 3 and 8. If one selects the aspect ratio for the ring-or toric section of the polishing surface in this range of values, one may possibly completely dispense with different tools for processing different workpiece surface geometries.
- the annular torus forming the ring-oring polishing surface has a main radius between 20 and 200 mm, most preferably between 30 and 80 mm.
- a broad spectrum of spectacle lens shell shapes can be efficiently polished with a high removal rate.
- Polishing tool on a preferably complementary to the polishing surface formed closed annular outer contour portion on which the elastic body is arranged and the elastic body has a constant thickness. This ensures that the elasticity of the elastic body, assuming a homogeneous material, is largely the same over the entire polishing surface. If the rigid support has a ring-shaped outer contour, on which the elastic body is arranged, and the elastic body has a constant thickness, a configuration of the polishing tool is obtained, which extends largely through
- the rigid support may have a hollow cylindrical portion with a flat end face on which the elastic body is disposed, the elastic body having a closed annular outer contour portion.
- This alternative variant of a polishing tool is characterized in that such tools are easy to produce.
- Polishing surface as radially outwardly directed annular half-shell surface or as a radially inwardly directed ring-shaped half-shell surface forms or when the closed ring-toric section has a radially outwardly directed Ringtowitz half-shell surface or a radially inwardly directed Ringtowitz half-shell surface as a partial surface. This allows improved polishing results. Improvements can already be achieved if one does not align the ring-shaped half-shell surface in the axial direction or if the polishing surface has a ring-shaped half-shell surface, which is not aligned in the axial direction.
- the elastic body is generally made of a material whose modulus of elasticity is greater than 0.02 N / mm 2 . Suitable materials are thus elastomers, such as rubber or rubber, in particular polyurethane, polyetherurethane or the like. This elastic body may for example be an injection molded part.
- a polishing pad As a polishing pad, a commercially available polyurethane-based polishing film can be used. Instead of a polishing foil and an abrasive coating can be applied to the elastic body.
- Polishing lip with a polishing surface having at least one closed ring or toric section is characterized in that a polishing tool is used whose rigid body acts as a carrier of an elastic body and a polishing pad.
- the elasticity of the elastic body allows an adaptation of the polishing surface to the surface contour of the surface to be polished and thus a flat polishing removal.
- the surface contact of the polishing surface and workpiece instead of a proposed in DE 44 12 370 A I point contact allows free-form surfaces to be polished with high dimensional accuracy and high efficiency. The stated object is therefore fully solved by the invention.
- the annular-adaptive trained polishing tool is preferably such over the
- Eyeglass lens or shell surface is moved or moved relative to this that is deformed by a compressive stress of the elastic body of the polishing tool on the eyeglass lens or shell surface.
- Eyeglass lens or shell surface the so-called contact surface is then not circular as in the method described in EP 1 251 997 B2 and also not punctiform as in the method described in DE 44 12 370 AI, but preferably strip to kidney-shaped.
- Mold shell surface considered.
- the geometry of the polishing surface and the geometry of the spectacle lens surface or of the casting shell surface are incorporated in the actually performed relative movement between the polishing surface and the workpiece surface.
- the contact surface ie the partial surface of the polishing surface which is brought into contact with the workpiece surface, is interposed in dependence on the geometry of the polishing surface and the geometry of the spectacle lens surface or the casting shell surface by corresponding relative alignment between the polishing tool and the workpiece and corresponding feed movement direction Polishing tool and workpiece controlled.
- the invention differs from the teaching of DE 44 12 370 A I, which requires a constancy of the lead angle.
- the geometry of the polishing surface and / or the geometry of the spectacle lens or the casting shell surface is provided in the form of a mathematical description. In this way, a desired alignment and feed movement direction between the polishing tool and the workpiece can be calculated in advance and adjusted with the aid of a control device.
- Spectacle lens manufacturing usual freeform surfaces can be divided into a sequence of segments, which can be approximated in detail with minimally deformed rings of different radii. This realization would be a variety of annular
- Polishing tool this variety of polishing tools.
- the geometry of the spectacle lens surface or mold shell surface may be approximated, for example, by at least one toric surface segment or corresponding to the above idea by a series of such segments.
- the polishing tool and the polishing movement should be selected so that during the
- the currently polished surface portion on the spectacle lens surface is not circular as in the method described in EP 1 251 997 B2 and also not punctiform as in the method described in DE 44 12 370 AI, but approximately strip or kidney-shaped.
- the shape may also differ greatly from the circular arc.
- the described polishing can be done in a single overflow in the feed direction or in several individual overflows, which can also be arranged side by side parallel or approximately parallel to the feed direction.
- the method variant may be advantageous in the case of spectacle lens surfaces, which are characterized by very great variance of the surface curvatures.
- the polishing tool is moved relative to the spectacle lens or the mold shell touching the spectacle lens surface or the mold shell surface with the polishing lip on a contact surface and if an inclination of the polishing tool against the spectacle lens surface or G confuseformschalenober Structure while minimizing the differences in the deformation of the elastic body within the contact surface is adjusted.
- Touch surface is compressed as evenly as possible. If the shape of the polishing surface and the shape of the workpiece surface to be polished are known, it is always possible to find surface portions which are approximately complementary to one another and which can be brought into abutment with one another by suitable positioning and guidance.
- Polishing tool is adjusted so that the respective average radius of the currently covered Surface segment is continuously approximated best fitting. By targeted deviation from the best-fitting angle of attack, the pressure distribution can be controlled. In addition, the polishing pressure for each currently covered area segment of the spectacle lens or the mold shell can be continuously determined by the delivery of spectacle lens surface /
- the calculation of the relative movement between polishing tool and workpiece and their control is preferably carried out computer-aided.
- the invention therefore sees the
