For realization of high precision centerless grinding, high rigidity and high precision servo-controlled regulating wheel spindle system is newly designed. On this system truing method of regulating wheel is studied for accuracy and the followings are concluded : (1) Truing accuracy with single point diamond dresser is by far lower in roundness and profile comparing with motion accuracy of wheel spindle and dresser feed. (2) Newly proposed truing method of regulating wheel with grinding wheel gives higher shape accuracy by one order comparing with conventional method. (3) Ground surface of regulating wheel is preferable in both friction and wear characteristics, and redressing life is much extended. (4) Ground regulating wheel excellently improves machining accuracy. For example, roundness error improves from 1.7pm to O.2pm and surface roughness from O.32μmRa to O.12μmRa in comparison with the case of conventionally trued regulating wheel.
