味は良好になる。As a method for producing the above-mentioned crushed alumina abrasive grains, there is a method of producing a water-soluble matrix at the grain boundaries of alumina crystals when melting and solidifying molten alumina, and then pouring a solidified mass into water to obtain particles. However, it is also possible to granulate using mechanical grinding. In the present invention, it is preferable that the crushed alumina abrasive grains be produced by mechanical pulverization to produce single crystal particles in that a very sharp shape can be imparted to the tip of the particles. By using a crushed alumina abrasive having a sharp particle tip, the sharpness of the grinding wheel is improved.

This heating / quenching treatment is performed as a treatment for increasing the internal stress of the abrasive grains and easily causing microcracks. Specifically, the alumina-based particles are heated to a temperature of 700 ° C. or higher and lower than the melting point of the alumina-based particles, Thereafter, the cooling is performed by rapidly cooling the temperature to 0 ° C or more and 100 ° C or less.

脱落させることができる。In the present invention, by using brown alumina abrasive grains in combination with "other abrasive grains", excessive removal of the abrasive grains from the vitrified binder is suppressed, and the grinding ratio of the grinding stone and the easiness of deformation are reduced. Can be improved, and good grinding can be continued even if the dress interval is lengthened, thereby improving grinding efficiency. This is because the vitreous components such as SiO 2 contained in the brown alumina abrasive grains generate a high bonding force with the vitrified binder, and the brown alumina abrasive grains are prevented from falling off, so that the surrounding “other abrasive grains” It is considered that this is also to suppress the easy falling off. That is, in the grindstone of the present invention, the brown alumina abrasive grains are considered to have an effect of extending the falling time of the “other abrasive grains”, and by adjusting the ratio of the brown alumina abrasive grains, the viewpoint of grinding performance is improved. The "other abrasive grains" can be dropped off after the desired drop-out time is extended.

易くなる。Such an effect is particularly obtained when the ratio of the brown alumina abrasive grains to the total of the brown alumina abrasive grains and the “other abrasive grains” is 3 to 20% by volume, preferably 5 to 18% by volume, and more preferably 7% by volume. It becomes remarkable when it is １５15% by volume. As the ratio of the brown alumina abrasive grains becomes smaller at less than 3% by volume, the frequency of the "other abrasive grains" dropping out becomes too high, the wear of the grindstone becomes faster, the grinding ratio is reduced, and the grindstone is easily deformed. Become. In addition, the ratio of brown alumina abrasive grains is 20
"Other abrasive grains"
The frequency of the falling off becomes too small, and the sharpness of the grindstone is apt to decrease.

好な研削を継続することができる。When the object to be ground is ground using a grindstone, the grinding resistance increases as the grinding progresses and the abrasive grains wear out, and the abrasive grains easily fall off. In the grindstone of the present invention, the brown alumina abrasive grains have a larger bonding force with the binder than the "other abrasive grains", so the "other abrasive grains" first fall off,
As described above, the drop-off time is extended, and even during the drop-off, grinding with brown alumina abrasive grains continues, so that the shape of the grindstone is suppressed and good grinding continues even if the dress interval is lengthened. can do.

ることができる。In the case of using the crushed alumina abrasive grains which have been subjected to the above-mentioned heating and quenching treatments, the abrasive grains have a considerable internal stress and are distorted. When the grinding force increases and the external force applied to the abrasive grains increases, microcracks occur on the exposed surface of the crushed alumina abrasive grains, and a part of the abrasive grains (tips having a worn surface) from there. Is crushed and removed. As a result, a new sharp cutting edge is generated by crushing on the exposed surface of the remaining portion of the abrasive grains, so that sharp grinding can be continued without further increasing the grinding resistance. In addition, since the abrasive grains regenerate the cutting edge by their own partial destruction, the abrasive grains can be used effectively, the wear of the grindstone is small, and the grinding ratio can be greatly improved.
