This paper describes an experimental investigation on the effects of ultrasonic vibration in the truing of the small CBN grinding wheel. In the present work, a new truing technique is proposed, where the grinding wheel is ultrasonically vibrated in its axial direction during the truing operation using a rotary GC cup dresser. In order to validate the proposed technique, experiments are carried out. The influences of the truing parameters on the truing force and the run-out of grinding wheel were investigated. The truing force applying ultrasonic vibration to the grinding wheel decreases more than 22% compared with that without ultrasonic vibration. The run-out of grinding wheel with ultrasonic vibration is achieved less than 0.8μm from original value of 150μm, while that obtained without ultrasonic vibration is more than 1.1μm.
