Definitions

  • the present invention relates to a polishing plate for a tool for fine machining of optically active surfaces, according to the preamble of claim 1.
  • Such polishing plates are used in particular in the production of prescription eyeglass lenses in bulk.
  • 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 pre-processing of the optically effective surfaces of spectacle lenses u.a. Depending on the material of the lenses by grinding, milling and / or turning done, the optically effective surfaces of spectacle lenses are usually subjected to a fine grinding, lapping and / or polishing during the finishing.
  • the prior art eg EP 1 249 307 A2, DE 102 48 104 A1, DE 102 50 856 A1, DE 103 19 945 A1
  • polishing plates which have an at least three-layer or -lagigen structure, with (1) one of the tool spindle facing, solid or rigid support body to which (2) a foam layer is attached, the (3.) rests a grinding or polishing foil facing the workpiece as a processing-active tool component.
  • 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.
  • liquid polishing agent An essential prerequisite for a trouble-free polishing process and durable tools as well as for obtaining high-quality machining results is a good supply of liquid polishing agent during processing.
  • the latter has abrasive components which are to be transported by means of the liquid to the point of engagement between the tool and the workpiece, and further serves for cooling and flushing at the point of engagement between the tool and the workpiece.
  • the polishing agent supply takes place from the radially outside via flexibly adjustable hoses whose outlet openings are positioned as close as possible to the working gap between the polishing foil and the surface of the spectacle lens to be machined.
  • the invention is based on the object, starting from the prior art, as he e.g. represented by the DE 102 50 856 Al, to provide a simply constructed polishing plate for a tool for fine machining of optically active surfaces on particular eyeglass lenses, which is used as long as possible in achieving high surface qualities.
  • a polishing plate for a tool for fine machining of optically effective surfaces on in particular spectacle lenses which has a carrier body, to which a foam layer is fixed, which rests on a polishing film
  • the polishing film is provided in a central region with at least one opening.
  • the opening according to the invention in the polishing foil provides a fluid connection between an inner region of the spongy foam layer soaked with polishing agent during processing and the outer surface of the polishing foil in machining engagement with the surface of the workpiece 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 film and the surface to be machined of the workpiece, whereby at these engagement areas due to increased wetting of the polishing film or a more uniform polishing agent on this better rinsing and Cooling is ensured. Accordingly, it no longer results in partial solidification of the polishing film which is detrimental to the surface quality produced, so that the polishing plate can be used longer as compared with the above prior art.
  • the opening according to the invention virtually performs a valve function:
  • the polishing-active surface of the polishing plate and therefore the polishing film must have a relatively high flexibility.
  • the polishing film is relatively strongly deformed in particular during the passage of the polishing plate on the edge of the lens to be processed but also in the processing of, for example, toric surfaces during rotation of the tool and workpiece.
  • the underlying foam layer which is saturated with the liquid polishing agent, is forced to flex; The result is a pumping effect between different areas of the top and bottom covered foam layer.
  • the opening can be cross-shaped, star-shaped, curved or S-shaped, elliptical or the like. be educated.
  • a plurality of openings may be provided, in shape and distribution, for example as the mounting holes on a button.
  • a recess in the foam layer adjoins the at least one opening in the polishing film in the direction of the carrier body.
  • This recess can advantageously serve as a reservoir for the liquid polishing agent. But it is also conceivable that no recess is provided here, but the foam layer ends directly and openly pores on the at least one opening in the polishing film.
  • a recess is provided in the foam layer, it may extend as far as the carrier 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.
  • the polishing film can project beyond an outer circumference of the recess in the foam layer inwards.
  • the polishing film in the direction of the carrier body can yield more easily; it comes to a rounding or to a natural radius of the polishing film.
  • can be so undesirable on the surface processed by means of the polishing pad Can be avoided, which could otherwise be caused by a more or less sharp edge of the polishing film, which is formed when the at least one opening in the polishing film is made by cutting or punching.
  • the polishing film can project beyond an outer periphery of the foam layer to the outside.
  • the polishing foil is intentionally kept larger in its radial dimensions than the underlying foam layer, that is, has a certain overhang with respect to the foam layer, the polishing foil spreads slightly in this area of the surface to be machined.
  • unwanted impressions are avoided, as already described above; In this case no significant polishing pressure can be exerted on the surface to be machined over the outer edge of the polishing film.
  • the overhang of the polishing film with respect to the foam layer also leads to a further improvement of the polishing agent supply: Between the surface of the spectacle lens just worked and the overhanging part of the polishing foil which is slightly folded away, a capillary gap which opens radially outwards forms, even at high temperatures Speeds always carries a certain amount of polish with it. The thus created additional polishing agent reservoir is not thrown off, but carried along with each movement and is thus constantly available.
  • the carrier body can be provided with a depression for orientation of the foam layer, which in particular simplifies the attachment of the foam layer to the carrier body.
  • the edge delimiting this depression clearly defines the mounting location for the foam layer and thus also serves as an aid in the application of an adhesive for fastening the foam layer to the carrier body.
  • the edge defining the depression provides also for a certain positive fit of the foam layer on the carrier body.
  • an embodiment of the polishing plate is furthermore preferred in which the carrier body for fixing the foam layer has a carrier surface preformed in accordance with the macrogeometry of the surface to be processed, e.g. in the case of processing a toric surface has a corresponding toric preform.
