Definitions

  • the present invention relates to a brush material that can be used for polishing the surface of a workpiece or for polishing and grinding it for burring.
  • a conventionally known brush material that can be used for polishing the surface of a workpiece or for polishing and grinding it for burring is, for example, a brush material that includes as a core a plurality of synthetic fibers containing abrasive particles and as a covering a thin multifilament of synthetic fiber provided around the core (see JP-A SHO 63-318907 ).
  • WO 93/18890 shows a composite abrasive filament comprising at least one preformed core, a plurality of which cores may be parallel or twisted together, and at least partially coated with a thermoplastic elastomer having abrasive particles therein.
  • the brush material including the covering of the thin multifilament of synthetic fiber is used for polishing the surface of a workpiece or for polishing and grinding it for burring, and used under severe conditions such as being brought into contact with the surface of the workpiece, while being rotated at high speed, or being subjected to a strong pressing force, a burring effect or a polishing effect cannot be expected when a hard burr is formed on the surface or corner of the workpiece, and there is a need for improvement.
  • the present invention has been achieved to solve the above described problem, and has as an object to provide a brush material having wear resistance and durability so that a burring effect or a polishing effect can be expected even when a hard burr is formed on the surface or corner of a workpiece in the case where the brush material is used for polishing the surface of the workpiece or for polishing and grinding it for burring, and used under severe conditions such as being brought into contact with the surface of the workpiece while being rotated at high speed, or being subjected to a strong pressing force.
  • the invention provides a brush material comprising a brush bristle material that is composed of a bundle of plural metal brush bristles each having a circular or polygonal section; and a covering layer that contains an abrasive and is provided on a surface of the brush bristle material characterised in that each of the metal brush bristles has an abrasive layer formed by electrodepositing an abrasive on a surface of each metal brush bristle.
  • the covering layer may contain as the abrasive at least one member selected from the group consisting of alumina, silicon carbide, cerium oxide and diamond.
  • the covering layer may contain as the abrasive plural members comprising 1% to 10% by weight of diamond and 90% to 99% by weight of other members.
  • the covering layer may have a resin coated thereon, a resin coat wound thereon in a spiral shape or a pipe member of thin resin film mounted thereon.
  • the covering layer may contain aromatic or deodorant powder.
  • the brush bristle material may include the covering layer provided on the surface of the resin brush bristle material composed of a bundle of plural brush bristles.
  • the brush material has wear resistance and durability, and a burring effect or a polishing effect can be expected even when a hard burr is formed on the surface or corner of a workpiece in the case where the brush material is used under severe conditions such as being brought into contact with the surface of the workpiece while being rotated at high speed, or being subjected to a strong pressing force.
