Title: METHOD AND DEVICE FOR BALANCING ROTORS
Abstract:
The invention relates to a method for balancing rotors, in particular rotors pertaining to toolholders of metal-cutting machine tools. According to the inventive method, the balance error of the rotor is determined in a balancing machine computer with respect to size and direction, and is compensated by spreading at least two compensating elements with defined balance error to corresponding adjustment positions. First of all, the adjustment positions of the compensating elements are determined from the measured balance error of the rotor, and from the extent of the balance error of the compensating elements. The rotor is then rotated in the balancing machine until a compensation position is attained, in which the adjustment position of one of the balance elements is in a predetermined position in relation to the balancing machine. When the rotor is in the compensating position, a visible marking is made on the compensating element. Said element is then set to its adjustment position by making a mark on the starting element coincide with the visible marking. These last steps are repeated for the other compensating element. The device for balancing rotors has a marking device which is controlled by the computer and places visible markings on the compensating elements when the rotor is in its compensating position. This is when the adjustment positions of the compensating elements are in a predetermined position in relation to the balancing machine.
