A type that has an abrasive grain layer made of dispersed superabrasive grains such as BN, and this abrasive grain layer is formed on a whetstone base metal, and an all type that does not have a whetstone base metal and consists only of an abrasive grain layer. There is a blade type.

研削屑の排出性が不十分であるといった欠点があった。``Problems to be Solved by the Invention'' By the way, in such a metal bonded grindstone, the coefficient of friction between the metal binder phase and the material to be ground is large, so the grinding resistance is large, and chipping and sluggishness are large. , there was a risk that the grinding wheel would overheat due to frictional heat. In addition, because the metal binder phase is densely formed, the superabrasive grains are difficult to fall off, and chip pockets on the surface of the low grain layer are difficult to form.
There was a drawback that the discharge of grinding debris was insufficient.

た。Therefore, in order to reduce the grinding resistance and facilitate the formation of chip pockets, metal-bond grinding wheels have been prototyped in which graphite powder is added to the metal binder phase. A new problem arises in that the strength of the grinding material decreases and the abrasive grain layer is easily damaged by the grinding load. It is also possible to obtain the same effect by mixing carbon fiber instead of graphite powder, but the specific gravity of carbon fiber is smaller than that of metal powder, and it is difficult to mix the two uniformly. Moreover, the surface of the carbon fiber has poor wettability with the metal binder, and sufficient bonding strength cannot be obtained at the interface between the two, making it impossible to obtain a satisfactory effect of improving the strength of the grindstone.

It has the following. The grindstone of the present invention may be one in which the abrasive grain layer is formed on the grindstone base metal, or may be an all-blade type whetstone consisting of only an abrasive grain layer. The amount of dispersion of the metal-coated carbon fibers is preferably 2 to 30 vol%. If the amount of this dispersion is less than 2 vol%, a sufficient effect of improving the strength of the whetstone will not be obtained, and if it is more than 30v○1%, the amount of carbon fiber exposed from the surface of the abrasive grain layer will increase, making the sharpness of the whetstone difficult. descend.

It is desirable that the temperature is about 100 oz. If the carbon fibers are shorter than this value, the aspect ratio of the carbon fibers will be small, and the effect of improving the strength of the grinding wheel will be reduced.

能である。For metal bond grindstones with such a configuration,
Since it is manufactured by mixing carbon fibers whose specific gravity is approximately equal to that of the metal binder by applying a metal coating to the metal binder, the carbon fibers have good dispersibility in the metal binder phase. At the same time, the metal coating increases the wettability between the carbon fibers and the metal binder, so that the bonding strength at the interface between the carbon fibers and the metal binder can be increased. Therefore, with this grindstone, it is possible to significantly increase the strength of metal bond opening, and improve the grindstone strength and grinding ratio.

Since the carbon fibers are exposed on the metal binder surface, the coefficient of friction between the metal binder surface and the material to be ground can be significantly lowered, and the grinding resistance of the grindstone can be reduced. Therefore, it is possible to prevent the material to be ground from chipping or sluggishness, and it is possible to prevent the grindstone from overheating.

上させることができ、砥石の目詰まりが起こりにくい。In addition, the carbon fibers exposed on the metal bond surface partially peel off from the metal bond opening during grinding, forming groove-shaped chip pockets in the traces, which improves the drainage of grinding debris. The grindstone is less likely to become clogged.
