This paper describes influence of a land ratio and a number of land on the grinding characteristic of segmental wheels in creep feed grinding experimentally and theoretically. It has been proved that segmental wheels have the effect of reductions in grinding force, grinding temperature and wheel wear. However, these merits of segmental wheels are not available without both the optimum land ratio and the optimum number of lands which are appropriate to a given grinding condition. Practically, these optimum conditions are determined by the method of trial and error. As a result of experiments and theoretical analyses of cutting force and wear, the followings became evident. (1) The optimum condition exists in combinations of the land ratio and the number of lands. At this condition, grinding force and wheel wear are reduced to a minimum. (2) Cutting force per one cutting edge has a maximum at a front part of a land, and is reduced at rearward part of the land. Therefore, the wear behavior of cutting edge on the land varies with its position. (3) The optimum condition of the land ratio and the number of lands can be determined according to the theoretical analyses.
