Description

  The present invention is for polishing or deburring a hole or hole provided in a finished product or a semi-finished product (hereinafter simply referred to as a workpiece) or an inner surface of an inclined hole or hole, for example, by driving a motor. The present invention relates to a convenient net-type brush manufacturing method and a net-type brush.

  Conventionally, a torsion brush has been used to polish the inside of a work having pores. The torsion brush is produced, for example, by twisting a bristle portion after sandwiching a bristle material between a plurality of core wires. Further, the torsion brush is used by attaching an iron pipe or a brass pipe to a portion other than the brush region of the core wire portion.

  Moreover, the brush described in Unexamined-Japanese-Patent No. 2003-164332 is produced by pinching | interposing a metal wire between the three metal wire materials, and twisting these. A metal hollow pipe is inserted into the twisted portion of the brush, and the outer periphery is wrung and fixed by fitting.

Furthermore, the brush described in Japanese Patent Application Laid-Open No. 2002-254277 impregnates a binder resin made of a plurality of alumina continuous fibers into a binder resin, cures it, and binds it. The plurality of alumina long fibers can be subjected to polishing such as deburring at a free end which is not cured with the binder resin.

  As described above, the conventional twisting brush is produced by interposing a bristle material between a plurality of core wires and then twisting this portion. The brush can have a core portion when used by hand. However, when the brush is driven by a motor or the like, an iron pipe or a brass pipe is used as a shank connected to a core wire.

  The brush driven by the motor or the like has a problem in that the center of the brush and the shank cannot be accurately set, and unevenness occurs in polishing, polishing, deburring, and the like due to center blurring.

  In recent years, works such as mechanical parts used in mobile phones have been increasingly miniaturized. After the mechanical parts are manufactured, burrs generated on the surface, holes, and the like must be removed. However, as the size of the mechanical component is reduced, it is difficult to produce a deburring brush. In particular, development of an ultra-small polishing tool has been desired for deburring the inside of the pores and in the recesses.

  In particular, burrs generated in holes perpendicular to the pores are difficult to remove with a torsion brush or the like. That is, there is a problem that burrs generated at the corners where the holes intersect are difficult to remove with a brush parallel to the core wire.

  In order to solve the above-described problems, the present invention provides a net-type brush manufacturing method and a net-type that have less center blurring and are suitable for polishing or deburring in a predetermined region when the brush is used while being rotated. The object is to provide a brush.
