    摘要: A method of using a diamond cutting tool for ornamentation purpose is provided. The method includes positioning a work piece in proximity to a cutting tool. The cutting tool includes a shank. Further, the cutting tool may extend longitudinally from the shank and coaxial therewith. The cutting end includes a cutting end comprised of, but not limited to, a compact mass of sharp diamond dust. Further, the method includes activating the cutting tool to perform one of cutting and polishing of at least a portion of the work piece. Herein, activating the cutting tool enables movement of the cutting tool for positioning thereof. Further, activating the cutting tool may enable spinning of the cutting end to perform one of cutting and polishing of a portion of the work piece based on the positioning of the cutting tool.

    摘要: A wire saw has a small diameter metal wire and a layer of abrasive grains firmly affixed to the wire surface by a brazed active metal bond. Preferably, the grains are present in a single layer. The grains are disposed on the surface of the wire in a preselected surface distribution. The wire saw can be made by a completely continuous process involving coating the wire with a paste of metal bond powder components combined with a fugitive liquid binder composition. Abrasive grains are deposited into a layer of the paste. Thereafter, the bond composition is fused at elevated temperature to braze the grains to the wire. The abrasive grains can include superabrasive materials, such as diamond and cubic boron nitride. Accordingly, the novel wire saw is suitable for cutting ultra thin wafers ceramic wafers with minimum waste of the work piece.
