As a basic study for grinding characteristic of grinding wheel, the irregularity of grade is investigated. Also the relationships between the elastic modulus measured with the ultrasonic pulse method, the composition of grinding wheel, the density of cutting edges and the contact stiffness between the grinding wheel and the workpiece are discussed. The results obtained are as follows : (1) It is able to measure the irregularity of grade with the ultrasonic pulse method, because the contact stiffness can be predicted from the elastic modulus of the grinding wheel on which the grain size is known. (2) The contact stiffness increases linearly with the density of cutting edges. (3) In case of the same grade of grinding wheel, the contact stiffness increases with the grain size. (4) Even though it is under the same grain size of grinding wheel, the density of cutting edges increases with the grade.
