This paper aims to estimate the fracture rotating speeds of grinding wheels by applying proposed mathematical model. Since the fracture of grinding wheels initially takes place in internal area of wheels, comparing the stresses due to the centrifugal force in this area to fracture stresses, fracture rotating speed of wheels can be estimated. From such a viewpoint, estimated results of fracture speeds coincide with the fracture test. As the results written above, it is clarified that fracture rotating speed can be estimated quantitatively by means of the proposed mathematical model.
