Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is for deburring metal materials,
The present invention relates to a polishing tool used for polishing or when polishing a surface of a wood, a plastic, or another material to be polished.

[0002]

2. Description of the Related Art As is well known, various kinds of polishing tools have been conventionally used for polishing the surface of various materials to be polished or removing burrs. The most common type of polishing tool is a brush, and for example, there is a brush in which a large number of fiber materials such as synthetic fibers are planted on a rod-shaped or plate-shaped support tool. Also,
Conventionally, a hard grindstone made of an inorganic stone material has been known.

[0003]

However, although the above-mentioned brush can be used for a certain purpose,
When grinding the surface of wood, plastic, etc., it may not be possible to use it due to its weakness. Further, a hard grindstone made of stone material is difficult to be attached to a polishing apparatus or a polishing tool because of its poor shape processability. In addition, it is easily cracked or broken during use, and in that case, it is necessary to adjust the shape again. As described above, the use of the grindstone is limited to a very narrow field and range. Therefore, there is a demand for a polishing tool that has sufficient strength, is excellent in shape processability, and has a high polishing effect without cracking or chipping.

The polishing member and a plurality of wire rods arranged so as to be orthogonal to the length direction are bent and bent from substantially the center, and the bent portion is inserted and clamped together with the second core member into the second clamp having a U-shaped cross section. Since the second polishing member is formed in parallel with each other, the polishing device or the polishing tool can be configured only by attaching the first clamping metal member and the second clamping metal member to the sliding mechanism or the rotating mechanism. Therefore, in the polishing tool of the present invention, a first polishing member having a polishing portion made of a sheet material formed by mixing polishing abrasive particles with a synthetic resin and a second polishing member having a polishing portion made of a wire such as metal fiber are arranged in parallel. Therefore, it can be used for extremely various purposes as a polishing tool having the characteristics of each polishing portion. For example, since the sheet material is somewhat softened by frictional heat during polishing, the contact with the surface to be polished becomes soft and the finished surface is extremely good. Moreover, since the sheet material is made of a mixture of synthetic resin and abrasive grains, it has a moderate elasticity, is not soft like a brush, and is not extremely hard like an inorganic grindstone, so it can be damaged or broken. In addition, since it has excellent workability, it is easy to form a polished surface (portion) according to the shape of the surface to be processed, especially for deburring metal materials, wood surfaces, and plastic surfaces. ,
It can be practically used for grinding and polishing the surface of other materials to be polished. Further, the wire may be made to have a polishing effect by using, for example, a metal fiber or a synthetic fiber having abrasive grains fixed on the surface, and it is possible to perform finer polishing as compared with the above-mentioned sheet material, Effective for finish polishing. Further, by using the above-mentioned sheet material and wire together, the following synergistic effect can be obtained.
That is, since the wire material is removed from the surface to be treated, such as burrs, polishing powder, and polishing pieces scraped off by the sheet material, it can be carried out while checking the progress of the operation during deburring or polishing / grinding work. There is no danger of performing unnecessary polishing and grinding. Further, the brush composed only of the wire rod is likely to tilt or break during continuous use, but since the sheet material of the polishing tool of the present invention prevents the wire rod from tilting, it is possible to continuously and stably perform the constant polishing. it can.
