An apparatus and method for balancing a high speed rotary tool assembly (1) is provided. The apparatus includes a rotary tool holder (3) having an axis of rotation (11), a cutting tool retainer (13) in the rotary tool holder (3) having a lockring (23) that circumscribes the axis of rotation (11) of the holder (3), and a pair of axially spaced balancing rings (35a, 35b) for balancing the entire rotary tool assembly (1) which are rotatably mounted around bearing surfaces (37) circumscribing the locking (23) so as to be angularly positionable around the axis of rotation (11) of the tool holder (3). In the method of the invention, the unbalance of the tool holder (3) and cutting tool (17) is determined, and then the rings (35a, 35b) are rotatably adjusted about the bearing surface (11) on lockring (23) to create an unbalance which cancels out the unbalance of the tool holder (3) assembly.
Appareil et procédé permettant d'équilibrer un ensemble outil rotatif rapide (1). L'appareil comprend un porte-outil (3) rotatif présentant un axe de rotation (11), un dispositif de retenue (13) de l'outil de coupe situé dans le porte-outil (3) qui comprend un bague (23) de verrouillage entourant l'axe de rotation (11) du porte-outil (3), et une paire de bagues (35a, 35b) d'équilibrage espacées axialement qui servent à équilibrer l'outil rotatif (1) et qui sont montées rotatives autour des surfaces (37) de support qui entourent la bague (23) de verrouillage de manière à pouvoir être placées en position angulaire autour de l'axe de rotation (11) du porte-outil (3). Selon le procédé, le balourd du porte-outil (3) et de l'outil (17) de coupe est déterminé, puis les bagues (35a, 35b) sont ajustées en rotation autour de la surface (11) de support de la bague (23) de verrouillage pour créer un balourd qui annule le déséquilibre déterminé de l'ensemble porte-outil (3).
