In particular, it relates to ultra-hard grinding composite grindstones, which have made it possible to ultra-finely refine high-hardness materials in an extremely rational and economical manner.[Prior art] There is a growing need for ultra-fine grains, but with conventional vitriphite-based and other grinding wheels, when grinding materials into ultra-fine particles that are equivalent to or harder than abrasive grains, the wear and tear of the grinding wheels is significant and long-term use is required. They were unable to cope with stable production. A solution to this problem is to use ultra-hard abrasive grains such as diamond or borazone (a trade name for boron nitride abrasives), but these abrasive grains are extremely expensive and require a It is economically impossible to use it over the entire surface.

In the present invention, diamond or borazone is used as the ultra-hard abrasive grains to be coated on the grinding surfaces of the mutually opposing outer peripheral convex portions of the metal wheel. There are various methods for coating, and although it is not particularly limited, for example, 50 to 100 coating methods are available.
Ultra-hard abrasive grains about the size of a mesh are coated with a metal bond using a nickel-copper bond. The ratio of bond used is 10 to 50 parts per 100 parts of abrasive grains.
section is appropriate. The width of the coating is preferably 5 to 30 mm, but since the coating is applied to the entire surface of the protrusion on the outer periphery of the metal wheel, it is necessary to prepare the protrusion on the outer periphery to the above width in advance depending on the object to be ground. be. It is preferable that the thickness of the coating is varied in the range of 0.1 to 5 mm depending on the object.
It is also possible to change the thickness of the layer between the stationary side and the rotating side.

のがある。 As a result of various studies, the present invention was made based on the discovery that during grinding, a load is applied to the convex portions of the outer periphery of the metal wheel that face each other, and the present invention was created by coating only these portions with ultra-hard abrasive grains. However, this also provides the following advantages: That is, when grinding a high-hardness material using the combination grindstone of the present invention, gouges occur in the gently sloped part of the internal grinding surface adjacent to the ultra-hard abrasive coating surface, and the ultra-hard abrasive coating layer Even though it is still working, the grinding function of the grindstone stops and it becomes unusable. In this case, by replacing the grinding wheel with the internal grinding surface, which is much cheaper than the abrasive grains in the ultra-hard coating layer, it is possible to restore the same function as new again, so you can replace the grinding wheel until the ultra-hard coating layer wears out. can be repeated many times, and its economic effects are immeasurable.

可能であり、その利用効果はきわめて大である。 In addition, when grinding inorganic materials, a porous grindstone such as a vitrified whetstone is used as a replacement whetstone for the internal grinding surface, and when grinding foodstuffs, a vitrified whetstone is used to prevent bacterial contamination and rot. It is possible to use different grindstones and replace them depending on the object to be ground, such as using a grindstone made of a polymer composite. Furthermore, depending on the application, it is naturally possible to replace the internal grinding surface with fine ceramics or metal, and the effects of this use are extremely large.
