Abstract:
A method for balancing rotors comprising tool holders and/or tools of machining devices, in the case of which the size and direction of an imbalance of the rotor is ascertained in a computer of a balancing machine and balancing is performed by spreading apart a first and a second balancing element with a predetermined degree of imbalance by movement into corresponding positions of adjustment, wherein:(a) the size of the imbalance of the respectively employed pair of balancing elements is supplied to the computer;(b) from the measured imbalance of the rotor and the size of the imbalance of the balancing elements the positions of adjustment of the balancing elements is ascertained;(c) the rotor is turned in the balancing machine until a first balance position is reached, at which the adjustment position of the first balancing element is at a predetermined position in relation to the balancing machine;(d) a first visible marking is projected onto the first balancing element, when the rotor is located in the first balance position;(e) the first balancing element is set in a position of adjustment by bringing a mark provided on the balancing element into alignment with the first visible marking; and wherein(f) the rotor is again taned in the balancing machine until a second balance position is reached, at which the adjustment position of the second balancing element is at a predetermined position in relation to the balancing machine;(g) a second visible marking is projected onto the second balancing element, when the rotor is located in the second balance position;(h) the second balancing element is set in a position of adjustment by bringing a mark provided on the second balancing element to alignment with the second visible marking.
