Abstract: Several method for evaluating the hardness of grinding wheels has been developed for more than 40 years. In this report, we investigated these method, aod found the new method that the hardness value was expressed quantitatively by mechanical-physical properties of the grinding wheel. The hardness value of grinding wheel is determined by the crushing strength of individual abrasive grain, the breaking strength of individual grain suppors (bonding bridge) and the holding force between two grains. We measured the crushing strength, the breaking strength and the holding force, and the hardness value (grade) of the grinding wheel was expressed being the function of these observations.
