Definitions

  • the invention relates to the surfacing of optical surfaces.
  • Surfacing means any operation to modify the surface condition of a previously shaped optical surface. These include polishing, grinding or etching operations to modify (decrease or increase) the roughness of the optical surface and / or to reduce the undulation.
  • US Pat. No. 1,665,292 already discloses a surfacing tool according to the features of the preamble of claim 1 for sanding the surfaces of the body of an automobile, comprising a thick felt pad and a support constituting a drive member itself. even driven for example by a flexible shaft from a motor.
  • the support has a flange to which are riveted flat elastic blades positioned radially. At their inner end, the resilient blades are sharpened so that they fit on the face of the flange located on the side of the felt pad, that is to say on the end face of the support.
  • the outer ends of the elastic blades are received in a pocket made of a double layer of leather one layer rests against the pad and the other covers the curved outer ends of the blades.
  • Between the flange and the central part of the buffer is disposed a helical spring welded to the support. Sanding by this grinding wheel is essentially done at its periphery.
  • the invention relates to a tool for surfacing an optical surface, which comprises a rigid support having a transverse end surface, an elastically compressible interface which is applied against and covers said end surface, and a flexible pad suitable for to be applied against the optical surface and which is applied against and at least partially covers the interface opposite and to the right of said end surface.
  • the tool In order to reduce the roughness of the optical surface, the tool is brought into contact with the latter while maintaining sufficient tool pressure on it so that, by deformation of the interface, the pad conforms to the shape of the optical surface. .
  • the optical surface is rotated, its friction against the tool being sufficient to jointly drive it in rotation.
  • the surfacing operation requires an abrasive that can be contained in the buffer or in the fluid.
  • the elastically compressible interface makes it possible to compensate for the difference in curvature between the end surface of the tool support and the optical surface, so that the same tool is suitable for a range of surfaces. optical curvatures and different shapes.
  • the range of optical surfaces that the same tool is able to plan is relatively limited .
  • this type of tool is particularly poorly suited to surfacing optical surfaces of complex shapes, called "freeform" in English, particularly aspherical, which by definition have a non-uniform curvature.
  • this type of tool is also poorly suited to optical surfaces having a convexity or concavity gap that is too pronounced relative to the tool: in the first case, the edges of the tool lose contact with the optical surface. ; in the second case, it is the central part of the tool that loses contact with the optical surface, resulting in incomplete surfacing.
  • a first is to reduce the diameter of the tool, that is to say, its overall transverse dimension, so as to restrict and locate the portion of the optical surface in contact with the tool. On such a portion located in fact, the contact of the tool with the surface remains more homogeneous than considering this optical surface taken as a whole.
  • a second option is, maintaining the diameter of the tool, to soften the interface, either by increasing its thickness, or by decreasing its elasticity.
  • optical surface manufacturers and in particular ophthalmic lens manufacturers, are resigned to using a large number of different tools, sizes and bends to cover the range of their surfaces. optics.
  • the invention aims in particular to solve the aforementioned drawbacks by proposing a surfacing tool which, while being adapted to a range of optical surfaces sufficiently large, in terms of curvatures (convexity, concavity) and shapes (spherical, toric, aspherical, progressive or any combination thereof, or more generally "freeform"), has good stability during surfacing, and allows surfacing at once safe, fast and of good quality while being of reduced cost.
  • the invention proposes a tool for surfacing an optical surface, which comprises a rigid support having a transverse end surface, an elastically compressible interface which is applied against and covers said end surface, as well as a flexible pad adapted to be applied against the optical surface and which is applied against and covers at least part of the interface opposite and to the right of said end surface, the buffer comprising a so-called central part which is at right of the end surface, and a peripheral portion which is transversely beyond said end surface, elastic return means connecting this peripheral portion to the support, the combination of said peripheral portion and return means forming means for stabilizing the tool during surfacing, said tool being adapted to perform a surfacing essentially at said central portion; the.
  • the same tool is adapted to surface surfaces whose convexity - or concavity - has compared to that of the tool a gap relatively pronounced, as it is particularly suitable for surfacing surfaces of complex shape, including toro-progressive.
  • the buffer is monoblock, its central and peripheral parts forming a single piece, to the benefit of simplicity of realization.
  • the pad has a plurality of petals projecting transversely from its central portion, which corresponds to the usual form in which the surfacing pads are made.
  • the buffer comprises a ring surrounding the central portion, so that when the buffer is monoblock, it is, in the absence of stress, in the form of a disc.
  • the interface may also comprise a central portion which is at the right of the end surface of the support, and a peripheral portion, which is transversely beyond this end surface, and which is interposed between the peripheral portion of the buffer and the return means.
  • the peripheral portion of the interface is, for example, in the absence of stress, in the form of a ring surrounding its central portion.
  • the tool may comprise a deformable ring transversely surrounding the support and interposed between the peripheral portion of the interface and the return means.
  • the ring will preferably be chosen with a circular longitudinal section.
  • the interface is monobloc, its central and peripheral parts forming a single piece, to the benefit of simplicity of implementation.
  • the interface is for example, in the absence of constraint, in the form of a disk.
  • the return means comprise for example an elastically flexible strip projecting transversely from the support, and connected to the support by a first end, and to the peripheral portion of the buffer by a second end.
  • this strip is rigidly anchored in the support by its first end, in favor of good stability of the tool.
  • the return means comprise a starry part fixed to the support and provided with branches each forming an elastically flexible strip.

  • the support 4 is generally cylindrical with symmetry of revolution and has an axis of symmetry denoted X, which defines a so-called longitudinal direction.
