Definitions

  • the present invention relates to a polishing plate for a tool for fine machining of optically active surfaces, according to the preamble of claims 1 and 3.
  • Such polishing plates are used in particular in the production of prescription eyeglass lenses in bulk.
  • the invention relates to a method for producing such a polishing plate.
  • 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. While the preprocessing of the optically effective surfaces of spectacle lenses takes place, inter alia, as a function of the material of the spectacle lenses by grinding, milling and / or turning, the optically effective surfaces of spectacle lenses become during fine machining usually subjected to a fine grinding, lapping and / or polishing process.
  • the polishing film can be adapted within certain limits to the geometry of the surface to be machined, both from “spectacle” to spectacle glass, which is to be processed, as well as in “dynamic” terms, ie during the processing of a specific spectacle lens, in which a relative movement between the polishing plate and the spectacle lens takes place.
  • the elasticity of the foam layer significantly influences the removal behavior of the polishing plate during the polishing process.
  • EP-B-1 711 311 a polishing plate with three-layer or -lagigem structure in which the middle, elastic layer in the radial direction from the inside to the outside is increasingly softened to polish lenses with irregularly curved freeform surfaces in a surface quality that should make post-processing unnecessary.
  • This outwardly increasingly softer formation is achieved in particular by the fact that the middle layer in the radial direction, ie from the inside to the outside has an increasing axial thickness, wherein the carrier body, the middle layer and the polishing foil ends together on a cylindrical outer peripheral surface of the polishing plate.
  • unwanted "marks" of the polishing plate on the machined surface produced by the edge of the polishing film are not addressed in this prior art.
  • the invention is based on the object, starting from the prior art, as he by the DE-A-10 2005 010 583 is represented to create a simple as possible polishing plate for a tool for fine machining of optically effective surfaces of particular eyeglass lenses, the edge of which does not reflect on the machined surface in the form of microstructures.
  • the invention also includes the provision of a method for the simple production of such a polishing plate.
  • a polishing plate for a tool for fine machining of optically active surfaces on particular eyeglass lenses which has a central axis base body to which a softer relative to the base body intermediate layer is fixed, which rests a polishing agent, the intermediate layer relative to the central axis, a radially inner region of substantially constant axial thickness and an adjoining radially outer region whose radial outer dimensions increase starting from the main body to the polish carrier, so that the elastic support of the polish carrier by means of the intermediate layer in its radially outer region decreases towards the outer edge of the polish carrier.
  • a second aspect of the invention comprises in a polishing plate for a tool for fine machining of optically active surfaces on in particular spectacle lenses having a central axis having base body to which a softer relative to the base body intermediate layer is fixed, which rests a polishing agent, the intermediate layer with respect to the central axis, a radially inner region of substantially constant axial thickness and an adjoining radially outer region, wherein the outer edge of the polishing medium carrier is held spaced apart from the latter by means of the radially outer region of the intermediate layer during the finishing of the optically effective surface.
  • the intermediate layer is thus functionally divided in the radially inner region of substantially constant axial thickness and an adjoining, radially outer region, which has the task to prevent the edge of the polishing plate on the machined surface in the form of microstructures.
  • the inner region has a substantially constant axial thickness, the elasticity or resilience of the polishing plate does not change seen here over the radius, in contrast to the prior art according to FIG EP-B-1 711 311 , This results in a suitable relative movement between the tool and the workpiece advantageously a uniform polishing removal achieved - Preston's hypothesis: the polishing removal is proportional to the product of polishing pressure and relative speed between the tool and workpiece - so that the workpiece with high topographical fidelity, that can be polished shape preserving.
  • the polishing removal decreases due to decreasing elastic support of the polishing medium carrier (claim 1) or a "keep away” of the same from the machined surface (claim 3) and thus the Possibility that the edge of the polishing plate on the machined surface "imprint" or can depict.
  • the edge region of the polishing plate in which the radially outer region of the intermediate layer, the latter provides in the first inventive variant of the polishing plate (claim 1) also ensures that over the radially inner region of the intermediate layer radially outwardly projecting outer edge of the polish carrier at his Movements is damped in the fine machining of the optically active surface therefore not swing freely or flutter and thus can not hit the machined surface so that it is reflected there.
  • the radially outer region of the intermediate layer even "pulls" the outer edge of the polishing agent carrier projecting radially outward beyond the radially inner region of the intermediate layer away from the machined surface in order to avoid said "impressions".
  • the circumferential contour formed by the radially outer region of the intermediate layer may in principle have any desired geometry as long as the radial outer dimensions of the radially outer region of the intermediate layer increase from the main body towards the polishing medium carrier (preferably continuously), e.g.
  • the radially outer portion of the intermediate layer may have a toroidal outer peripheral surface.
  • the intermediate layer may have a circumferential chamfer or edge rounding in the radially outer region on the side facing the polish carrier, wherein the polish carrier is also fixed, preferably glued, in the region of the chamfer or edge rounding to the intermediate layer.
  • a circumferential chamfer or edge rounding can be formed, to which the intermediate layer is fastened, preferably glued, to its radially outer region.
  • Such chamfers or edge rounding on the intermediate layer and / or the base body can be formed in a simple manner, for example by water jet cutting in the case of an existing intermediate layer of a foam or by suitable design of the injection mold in the case of an injection molded from a plastic body.
  • the main body it is possible for the main body to have an end face facing the intermediate layer, which is preformed toroidally in accordance with the macrogeometry of the surface to be machined, such as in FIG DE-A-10 2005 010 583 described. Investigations by the applicant have shown, however, that it is sufficient for the majority of processing cases when the base body has an intermediate layer facing, substantially spherical end face to which the intermediate layer is glued. On the one hand, this simplifies the polishing plate production and, on the other hand, reduces the number of polishing plates to be provided in the production of prescriptions for the fine processing of the spectacle lenses.
  • the polishing agent carrier can be provided in a middle region with at least one opening.
  • This opening in the polish carrier provides fluid communication between an interior region of the foam usually comprised of a sponge-like liquid pad soaked with liquid polish and the outer surface of the polish carrier in machining engagement with the workpiece surface to be machined.
  • the liquid polishing agent can circulate better and also pass from the interior of the polishing pad to the engagement areas between the polishing medium carrier and the surface of the workpiece to be machined, whereby at these engagement areas due to increased wetting of the polishing medium carrier or a more uniform polishing agent film on this better rinsing and Cooling is ensured.
  • the opening in the Polierstoff may not come to partial, the surface quality produced detrimental solidification of the polish carrier.
  • the opening in the Polierstoff may advantageous for a relief of the resulting by deformation of the intermediate layer in this hydraulic pressure, which could otherwise lead to about a partial destruction of the intermediate layer, as well as for an "internal cooling" of the polishing plate.
  • a recess in the intermediate layer adjoins the at least one opening in the polishing agent carrier in the direction of the base body.
  • a recess can advantageously serve as a reservoir for the liquid polishing agent.
  • a recess is provided in the intermediate layer, it may extend as far as the main body.
  • Such a continuous recess is not only particularly easy to produce, but also advantageously maximizes the uptake volume of the reservoir formed by the recess for the liquid polishing agent.
  • An even further enlargement of the polishing agent reservoir is possible by also adjoining the recess in the intermediate layer, a recess in the body.
  • the diameter of the recess in the intermediate layer increases (preferably continuously) starting from the opening in the polishing agent carrier toward the main body, for example by delimiting the recess by a conical inner circumferential surface of the intermediate layer. This causes - similar to the starting from the body to the polish carrier toward increasing radial outer dimensions of the radially outer region of the intermediate layer - a close to the opening in the polish carrier in the direction of the opening decreasing elastic support of the polish carrier through the radially inner region of the intermediate layer, even at higher polishing pressures Danger to meet that the opening edge of the polish carrier is reflected on the machined surface.
  • the maximum radial width of the radially outer region of the intermediate layer in the undeformed state of the polishing plate should be between 3 and 10% of the maximum total width of the intermediate layer in order to support the polishing agent carrier substantially constantly elastically on a surface as large as possible without that there is a risk of pictures of the polishing plate edge on the machined surface.
  • the polishing plates according to the invention can advantageously be used on a tool for fine machining of optically effective surfaces on, in particular, spectacle lenses, comprising a base body which can be attached to a tool spindle of a processing machine, a joint part which has a tilting and longitudinally movably guided receiving piece with respect to the base body, to which a bellows connects in the direction of the main body, by means of which the joint part is fastened to the main body so as to be capable of rotation, and a pressure medium chamber bounded by the main body and the joint part, which can be acted upon optionally with a (liquid or gaseous) pressure medium, whereby the polishing plate interchangeably the receiving piece of the joint part is held.
  • polishing plate is held by means of a snap connection on the receiving piece of the joint part.
