In order to describe quantitatively the grinding process of partially stabilized zirconia (PSZ) with metal bonded diamond wheel, the analytical method established for metal grinding is applied to the grinding process of fine ceramics, and the theoretical values are compared to the experimental values. It is made clear that the plunge grinding process of PSZ with metal bonded diamond wheel can be represented by five independent characteristic parameters such as the size generation acceleration, the wheel wear rate, the grinding system stiffness, the contact stiffness and the cutting stiffness. By the characteristic parameters, variations of the grinding force, the stock removal, the residual stock through a grinding cycle and the grinding cycle time can be predicted.
