Various types of grinding tools have been known in the past. These can be classified into grinding tools (grinding wheels) obtained by solidifying abrasive materials such as ultra-hard powder with a binder, and grinding tools (grinding wheels) obtained by solidifying abrasive materials such as ultra-hard powder with a binder, and grinding tools (grinding wheels) obtained by solidifying abrasive materials such as ultra-hard powders with adhesives, etc.; There are three types of grinding tools: grinding tools obtained by gluing (abrasive cloth paper), and grinding tools obtained by forming concave holes with a chisel or the like on the surface of a bar-shaped steel body material (grinding tools).

曲げによりクラツクを多く生じ寿命の点で問題が
ある。 Incidentally, in recent years, in response to the fact that the surfaces of objects to be ground, etc. have become more complex, grinding tools are required to have various shapes depending on the objects to be ground. However, the reality is that these grinding tools, with the exception of the above-mentioned coated abrasive paper, have a fixed shape and cannot be applied to various objects to be ground. In such cases, it is possible to deal with this situation to some extent by using coated abrasive paper, but since the base material of coated abrasive paper is cloth or paper, it has poor stability and cannot be used with other holding members. In addition, since the base material and the abrasive material are bonded together using an adhesive, many cracks occur due to bending, which poses a problem in terms of service life.
そこで、かかる問題を解消したものとして、近

在に行えると共に、形状安定性を付与できるとい
う利点を有している。 In order to solve this problem, in recent years, a grinding tool has been developed in which an electrodeposited grinding layer is formed by electrodepositing carbide abrasive grains (superhard powder) on the surface of a metal sheet (metallic plate). has been proposed (1977-
111759). And according to this grinding tool,
Since the base material is a metal sheet, it has the advantage of being able to be bent freely and having shape stability.
しかし、上述した研削具の場合、電着によつて
電着研削層を形成している構成であるため、次ぎ
のような問題がある。
However, in the case of the above-mentioned grinding tool, since the electrodeposited grinding layer is formed by electrodeposition, there are the following problems.
電着研削層は、電気分解や電気泳動によつて
金属シートの表面に定着させて形成するもので
あるので、荷電粒子の隣接定着となり、その気
孔率が大きくなると共に、表面の凹凸度が大き
くなり、目の細かい研削に適しない。 Since the electrodeposited grinding layer is formed by fixing it on the surface of the metal sheet by electrolysis or electrophoresis, charged particles become fixed adjacent to each other, increasing its porosity and increasing the roughness of the surface. Therefore, it is not suitable for fine grinding.
電着研削層は、その厚みが大きくなると、固
着性が低下するおそれが大きくなる。 As the thickness of the electrodeposited grinding layer increases, there is a greater possibility that the adhesion will decrease.
本考案は、上述した点に対処して創案したもの

ことにある。 The present invention was devised in response to the above-mentioned points, and its purpose is to enable close grinding and to maintain a stable base even when the thickness of the grinding layer is increased. To provide a bendable grinding tool which can be fixed to a material and has a smooth grinding surface.

The bendable grinding tool of the present invention as a means to achieve the above object has a thickness of 0.3~
The surface of a bendable metal plate of approximately 1 mm is coated with ultra-hard powder several times by repeated explosive spraying to increase its thickness.
It consists of a dense explosive sprayed abrasive layer of about 0.2 to 0.5 mm and a porosity of 3% (volume %) or less.

The bendable grinding tool of the present invention based on the above structure uses a metal plate with a thickness of about 0.3 to 1 mm as the base material, so it is bendable and maintains bending stability. In addition, an explosive thermal sprayed abrasive layer with a porosity of 3% (volume %) or less is applied to the surface of the metal plate by repeating the explosive thermal spraying several times, and is successively laminated on the surface of the metal plate, melting the surface and melting it into one piece. Since the explosive sprayed abrasive layer is formed by oxidation, the detonation sprayed abrasive layer reliably adheres to the metal surface, and since its porosity is low, the abrasive surface becomes dense and allows fine grinding to be performed.

It is characterized by the formation of an explosive thermal sprayed grinding layer, which increases the strength of the integration of the metal plate and the grinding layer, and also makes the surface smooth, making it possible to perform fine grinding. It is something that works.

２を形成するようにしている。 The metal plate 1 is an iron plate with a thickness of about 0.3 to 1 mm.
Mild steel plates, copper plates, etc. are used. Here, the thickness
The reason for setting the thickness to about 0.3 to 1 mm is to address the problem that if the thickness is less than 0.3 mm, the stability will be poor, and if the thickness is more than 1 mm, it will be difficult to bend and process. Then, an explosive sprayed grinding layer 2 is formed on this surface.

たものである。 The explosive thermal spray grinding layer 2 is a grinding layer formed by explosive thermal spraying of ultra-hard powder such as ceramics or tungsten carbide. The reason for using ceramics or tungsten carbide as the ultra-hard powder is based on the experimental results that show that there are few cracks caused by bending. The explosive thermal spraying grinding layer 2 is formed by explosive thermal spraying of ultra-hard powder multiple times.
It is formed by repeated steps, and its thickness is 0.2~
It is considered to be a dense grinding layer with a diameter of 0.5 mm and a porosity of 3% (volume %) or less, with an uneven shape observed on the enlarged surface. Explosive thermal spraying uses high-speed combustion energy generated by the explosion of a mixed gas of acetylene and oxygen to turn ultra-hard powder material into a semi-molten state, and then collides with the base material to form a thermally sprayed coating. It is something that is made to form. Here, the thickness of the grinding layer 2 was set to 0.2 to 0.5 mm based on the experimental results.
If the thickness is less than 0.5 mm, the grinding force is not sufficient and
This is done in consideration of the fact that if the thickness is more than mm, there may be a problem in the ability to follow the bending details with the metal plate 1.
そして、金属板１と爆発溶射研削層２とは、強

According to Method c633-69, the structure has an adhesive strength of 3.5 Kg/mm 2 or more.
次ぎに、上述した実施例に基づき、本考案の折

た結果、同様の結果を得た。 Furthermore, a copper plate with a thickness of 0.5 mm was used as the metal plate 1, and ultra-hard powder mixed with titanium carbide 83 (wt%) and nickel 17 (wt%) was applied to the surface by repeated explosive spraying 12 times. A 0.5 mm thick iron plate was used as the grinding tool and the metal plate 1, on which a 0.5 mm thick explosive thermal sprayed grinding layer 2 was formed, and ultra-hard powder made of ceramics was repeatedly explosively sprayed 12 times on this surface. A 0.5 mm thick iron plate was used as the metal plate 1, and ultra-hard powder made of tungsten carbide was repeatedly explosively sprayed 6 times on the surface of the metal plate 1. , a grinding tool with a 0.2 mm thick explosive thermal sprayed grinding layer 2 was also subjected to the same test as described above, and similar results were obtained.

る。 From the above results, it has been found that when an explosive spray forming layer is formed on a metal plate by explosive spraying, the adhesive strength between the two is strengthened, and dense grinding can be performed satisfactorily. I was able to confirm. This is because the grinding layer is formed by explosive thermal spraying, in other words, the ultra-hard powder is repeatedly explosively sprayed multiple times, so the ultra-hard powder forms a layer each time, and the next layer is formed. Even with thermal spraying, it can be melted and integrated into a thickness of 0.2 to 0.5 mm, and the porosity can be reduced to 3% or less,
This is thought to be due to the fact that the adhesive strength is strengthened and an uneven shape can be formed on the enlarged surface.

As is clear from the above explanation, according to the bendable grinding tool of the present invention, the thickness of the base material is
A metal plate with a diameter of approximately 0.3 to 1 mm is used to make it stable and bendable, and an explosive thermal spray abrasion layer with a porosity of 3% (volume %) or less is applied to the surface of the metal plate by repeating the explosive thermal spraying several times. Since the explosive sprayed abrasive layer is successively laminated on the surface and integrated while melting the surface, the explosive sprayed abrasive layer reliably adheres to the metal surface, and its low porosity makes the abrasive surface dense. This has the effect of allowing fine grinding to be performed.
