  • Polisher brush having wire-shaped grinding elements
    Patent number: 7434289
    Abstract: In the manufacture of a brush-shaped grindstone (3), embedding holes (310) are formed in a grinding element holding surface (311) of a holder (31) in mutually separated positions. A base end side of a plurality of wire-shaped grinding elements (32), formed such that a composite yarn composed of inorganic filaments is impregnated and hardened with a resin, is aligned, and rod assemblies (320) are thereafter formed by fixing the base end side of the plurality of wire-shaped grinding elements (32) with adhesive (71) in holes (60) of a die material (6), which is formed to have substantially the same size as the embedding holes (310) of the holder (31). The rod assemblies (320) are thereafter embedded in the embedding holes (310) of the holder (32), and fixed with adhesive (72). Whereby, removing burrs from a precision work component, performing polishing, and the like can be carried out with good efficiency and high precision.
