1. A method for balancing the out-of-balance of a shaft-wheel assembly, comprising a bladed wheel held at the end of a mechanical shaft, implementing the following steps:
a) measuring the out-of-balance value of the shaft-wheel assembly with respect to a longitudinal axis of the mechanical shaft;
b) measuring the position of at least two distinct target areas, present at the surface of the bladed wheel, with respect to a longitudinal axis of the mechanical shaft; then
c) removing a quantity of material at the surface of the bladed wheel, to reduce the out-of-balance value of the shaft-wheel assembly, as a function of the measurements made at steps a) and b).
