ABSTRACT:
A machine for balancing a rotating member includes hard bearing balancing apparatus for determining the magnitude and circumaxial location of imbalance. A sensor responds to the position of the rotating member. A computer receives signals from the balancing apparatus and the sensor and determines the location of one or more projectiles to be fired at the member. A firing mechanism including a piezoelectric actuator fires the projectiles in timed relationship with the rotation of the member so as to position the projectiles as required for balancing.
