  • Method of manufacturing multi-element tungsten carbide jewelry rings
    Patent number: 9155363
    Abstract: A method for manufacturing annular jewelry rings employing multiple annular elements, at least one of which is composed of tungsten carbide. All annular ring elements composed of tungsten carbide are produced directly from tungsten carbide plate. Using an electrical discharge machining apparatus employing a preformed cylindrical electrode, an aperture of predetermined diameter is drilled through a planar, tungsten carbide plate. Using a wire electric discharge machining apparatus, annular blanks are cut from the planar tungsten carbide plate, the outer surface of the annular blank being cylindrical and concentric with the inner, drilled surface of the annular blank. The inner and outer surfaces of the tungsten carbide annular blanks are cooperatively machined to allow additional annular elements composed of tungsten carbide and other materials to be integrally coupled to one another to form jewelry in the form of rings.
