Bonding test of thin grinding wheels has been performed, using bit type testing machine. Bit displacement and torque were inversely proportional to the bonding grade of wheels, and were more closely connected with the bond contents. The torque needed to pulling out a grain was obtained as a function of the amount of bond contents per one grain. It was found that, the higher the bonding grade wheel, grains were more breakable than the lower one.
