ABSTRACT:
A method of balancing a rotor (10), the said method comprising the steps of determining the position of the center of mass of a rotor (10) to be balanced prior to the rotor (10) being machined to its final dimensions, and machining the rotor (10) to its final dimensions by removing material substantially along the length of the rotor (10). The material is removed in the direction of its axis such that the center of mass of the rotor is adjusted to be substantially co-incident with its axis of rotation (22).
