Definitions

  • the method includes coupling a first abrading article of the plurality of interchangeable abrading articles to the rotatable support.
  • the coupling is followed by leveling of the fixture configuration prior to using the first abrading article, setting the adjustable level to a working level, and working the gemstone on the working surface of the first abrading article.
  • the registering feature is not associated with any specific hardware.
  • the registering feature may be a combination of flat and cylindrical surfaces, a single surface such as a convex, concave or conical surface and any other arrangement that ensures precise position and alignment of the abrading article so that its working surface rotates in a predetermined plane.
  • the working surface of the abrading article is coated with abrasive material.
  • the abrasive material is diamond powder.
  • the diamond powder may be of a single grade or sections of the abrading article may be coated by different grades of diamond powder.
  • the working surface of each of the plurality of abrading articles may be coated by diamond powder of different grades, as may be required by a particular gemstone working sequence.
  • the method further includes providing a fixture configuration 116 (Block 220) operable to hold gemstone 120 at an adjustable level relative to the registering plane 148, and placing gemstone 120 into fixture configuration 116.
  • the method also includes providing a plurality of interchangeable abrading articles 160.
  • Each of abrading articles 160 has working surface 162 and each abrading article 160 is operable to couple with rotatable support 140.
  • Working surface 162 of abrading article 160 is coated with abrasive material.
  • the preferred abrasive material is diamond powder. Any method of coating by diamond powder such as impregnation, electroplating or use of adhesive materials is suitable for coating of surface 162.
  • an abrading article may have different forms, although the simplest form of abrading article 160 is a disk-like article.
  • Surface 162 is a flat surface having a high degree of flatness. Flatness of surface 162 is especially important if the abrading article rests on flat surface 146 of rotatable support 140.
  • abrading article 160 would have a thickness of 1 mm to 6 mm.
  • Rotatable support 140 provides the necessary stiffness keeping working surface 162 flat when working a gemstone.
  • Abrading article 180 ( Figure 2D) has no support and should be thick enough not to wobble under the pressure of the worked gemstone.
  • the method includes coupling (Block 222, Figure 4) a first abrading article 160 of the plurality of interchangeable abrading articles to rotatable support 140 and retaining it on rotatable support 140.
  • Different retaining mechanisms may be operable to retain the abrading article on the rotatable support.
  • Figure 2A shows an exemplary embodiment where permanent magnet inserts 200 distributed across rotatable support 140 retain abrading article 160, which, in this case, should be made of a ferromagnetic material. Electromagnetic inserts may replace permanent magnet inserts 200.
  • nut 158a in Figure 2B engages thread 158b to retain abrading article 160.
  • fixture configuration 116 is leveled. After this, working (Block 226, Figure 4) of gemstone 120 on working surface 162 of first abrading article 160 may begin.
  • the rotatable support may consist of more than one material.
  • vacuum orifices may be inserts and surfaces 172 ( Figure 2C) and 184 ( Figure 2D) that may have keys or inserts (not shown) made of different materials.
  • the rotatable support may be built in such a way that it installs on existing gemstone working machines in a way similar to a conventional scaife. This enables application of the method of working a gemstone to existing gemstone working equipment while preserving the earlier made investments and further reducing the gemstone working costs.

Abstract

La présente invention concerne un procédé applicable au travail des pierres précieuses et permettant un échange rapide des outils et la poursuite du travail sans avoir à reprendre les mises à niveau de la pierre ou de l'outil. L'appareil comporte un support rotatif pourvu d'un axe de rotation et un organe de calage. Cet organe de calage présente avec précision un article abrasif interchangeable de façon que sa surface tourne dans un plan fixe bien défini par rapport à la pierre.
