In particular, it relates to ultra-hard grinding composite grindstones, which have made it possible to ultra-finely refine high-hardness materials in a very rational and economical way.[Prior art] There is a growing need for ultra-fine grains, but with conventional vitriphite-based and other grinding wheels, the wear and tear of the grinding wheels is significant when it comes to ultra-fine grinding of materials that are equivalent to or harder than abrasive grains, so They were unable to cope with stable production on time. To solve this problem, you can use an ultra-hard abrasive such as diamond or borazone (trade name for boron nitride abrasive).
Since these abrasive grains are several tens of times more expensive than the abrasive grains of commonly used bitrified whetstones or neuceramics whetstones, it is economically impossible to use them over the entire grinding surface of the whetstone.

In other words, the ultra-hard grinding composite grinding wheel of the present invention is coated with ultra-hard abrasive grains in a layer only on the part of the grinding wheel that is subjected to load during grinding, and the ring-shaped grinding wheel forming the outer grinding surface of the fixed disk and rotating disk is coated with ultra-hard abrasive grains in a layered manner. The grinding surfaces of the grinding wheels facing each other are coated with ultra-hard abrasive grains, and the inner grinding surface is equipped with a grinding wheel having a hardness lower than that of the ring-shaped grinding surface. It is.

In the present invention, the ultra-hard abrasive grains to be coated on the mutually opposing grinding surfaces of the metal wheel include:
Use Diamond or Borazon. The ring-shaped core forming the main body of the ring-shaped grindstone is made of metal or vitrified material, and a coating is applied to opposing surfaces thereof. The coating method is not particularly limited, but for example, in the case of a metal core, about 50 to 100 meshes of ultra-hard abrasive grains are metal bond coated on the metal surface using a nickel-copper bond. Alternatively, a method such as resintering the ultra-hard abrasive grains of the mesh onto the core using a vitrified binder can be used.
The appropriate ratio of these bonds or binders used is 10 to 50 parts per 100 parts of abrasive grains. The width of the coating is preferably 5 to 30 mm, and it is necessary to prepare the ring core to a predetermined width within this range depending on the object to be ground.
The thickness of the coating is preferably varied in the range of 0.1 to 5 mm depending on the object, and the thickness of the layer can also be varied between the stationary side and the rotating side.

経済的効果にははかり知れないものがある。 As a result of various studies, it was discovered that during grinding, a load is applied to the outer grinding surface, and the present invention was created by coating ultra-hard abrasive grains only on the grinding surfaces facing each other of the ring-shaped grindstone. 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, and replacing it with a ring-shaped grinding wheel, it is possible to restore the same functionality as new. It becomes possible to repeatedly replace the hard coating layer until it wears out, and the economical 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 grindstone is used as a replacement grindstone for the internal grinding surface, and when grinding foodstuffs, a vitrified grindstone is used to prevent bacterial contamination and rot. For example, a grindstone made of a polymer composite can be used, and the grindstone can be changed depending on the object to be ground. 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.
