In order to clarify the mechanical phenomena of grinding wheels in the contact area with workpieces, a mathematical model of wheel is proposed and a static analysis of grinding wheels is carried out. As the first step of this study, a wheel model consisting of rigid abrasive grains and bonds as spring elements with stiffness k is proposed. ln this model, grinding abrasives are uniformly arranged in body centered lattice and successive two grains are connected by a bond with static stiffness k. The amount of static stiffness of bond k deeply affecting on the mechanical phenomena in contact area is calculated with FEM analysis and the three points bending test of abrasive sticks. As the results of analysis, it can be clarified that the amount of k is determined only depending on the Brain size and the mechanical phenomena of grinding wheel in the contact area can be explained by using the amount of the static stiffness k.
