Through the previous works, it was found that the laminated grinding wheel is more efficient to generate smoother surface in short time than general grinding wheels. But, if the laminated grinding wheel is easily worn-out, it is impossible to apply this wheel in the real grinding process, because the periodic time for dressing is closely linked to the productivity of the process. So, it is required to investigate the wear of the laminated grinding wheel fer studying the periodic time for dressing. But it is difficult to analyze the dressing period quantitavely. Therefore, in this study, periodic times for dressing of the laminated grinding wheel and general grinding wheel are deduced from the relationship between the wear of grinding wheels and the surface roughness changes according to the number of traverse in cylindrical traverse grinding through experiments. This study shows that there are some differences in the wheel wear mechanisms between the general and laminated grinding wheels. As a result, it is also found that the periodic time for dressing of the laminated grinding wheel is longer than that of the general grinding wheel.
