Description

Brush material {BRUSH MATERIAL}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a brush material that can be used for polishing and grinding to polish a surface of a workpiece or to remove burrs.

Conventionally, as a brush material which can be used for polishing and grinding, such as polishing the surface of a workpiece or removing burrs, for example, a plurality of synthetic fibers containing abrasive particles are used as cores. There is known a brush material which is made by covering a synthetic fiber multifilament that is thin around. (See Patent Document 1)

[Patent Document 1] Japanese Patent Laid-Open No. S63 (1988) -318907

However, the brush material formed by covering the thin synthetic fiber multifilament is used for polishing and grinding such as polishing the surface of the workpiece or removing burrs, and contacting the surface of the workpiece while rotating at high speed, When used under severe conditions such as giving a strong pressing force, if the burrs generated on the surface or the edge of the workpiece are hard, no burr removal effect or polishing effect can be expected, and improvement has been desired.

The present invention has been made to solve the above problems, and is used for polishing and grinding such as polishing the surface of a workpiece or removing burrs, and the workpiece is brought into contact with the surface while rotating at high speed, or a strong pressing force is applied. When used under harsh conditions such as imparting, even if the burr generated on the surface or the edge of the workpiece is hard, it provides a brush material having resistance to wear and durability that can expect burr removal effect or polishing effect. It aims to do it.

In order to solve the said subject, invention of Claim 1 is a brush material formed by providing the covering layer which mixed abrasive material in the surface of the brush base material by which two or more metal brush hairs of a circular cross section or polygonal shape are focused. .

Moreover, the invention of Claim 2 is the brush material of Claim 1 which is the 1 type (s) or 2 or more types of alumina, a silicon carbide, a cerium oxide, and a diamond.

The invention according to claim 3 is the brush material according to claim 1 or 2, wherein the metal brush is electrodeposited with an abrasive on a surface to form an abrasive layer.

Moreover, the invention of Claim 4 is the brush material as described in any one of Claims 1-3 whose said covering layer is 1-10 weight% of diamonds, and 90-99 weight% of other abrasives.

In the invention described in claim 5, the covering layer includes any one of claims 1 to 4 wherein the covering layer is coated with a resin, a resin film is wound in a spiral shape, or a pipe material of a resin thin film is attached. The brush material according to one item.

The invention according to claim 6 is the brush material according to any one of claims 1 to 5, wherein an aromatic or deodorizing powder is mixed in the covering layer.

According to the brush material of the present invention, since the brush base material forms a covering layer on the surface of the resin brush base material in which a plurality of brush bristles are focused, it is resistant to abrasion and durability, and is brought into contact with the surface of the workpiece while rotating at high speed. In the case of being used under extreme conditions such as giving a strong pressing force or the like, burrs are generated on the surface or in the corners of the workpiece, and even if such burrs are hard, burr removal effect or polishing effect can be expected.
