The precision grinding process is carried out with fine-cutting operation after coarse-cutting operation. So, the laminated grinding wheel has been developed to reduce the ineffectiveness induced by changing the operations. In this study, to investigate the possibility of the practical use of the laminated grinding wheel, the surface residual stress of the workpiece ground by the laminated grinding wheels was compared with that ground by the general grinding wheel, and the influence of the difference in grain sizes, between the coarse grit and fine grit of the laminated grinding wheel, on the surface roughness of the workpiece was investigated.
