Abstract: A method for balancing a rotor, notably of a turbomachine, includes a step of determining an unbalancing mass, and a step of balancing by chemical machining of the rotor. The chemical machining includes arranging a bath containing a chemical machining agent so that the bath has a capacity of heterogeneous material removal as a function of the depth in the bath, an amount of material removal at a first depth in the bath is greater than an amount of material removal at a second depth in the bath; immersing the rotor in the bath; and orienting the rotor in the bath taking account of the capacity of heterogeneous material removal so that the quantity of material removed from the rotor in a zone of the unbalancing mass is sufficient to balance the rotor.

Abstract: The invention relates to a method for balancing a rotor, notably of a turbomachine, comprising a step of determining the unbalancing mass followed by a step of balancing by chemical machining of the rotor. More particularly, the chemical machining comprises the immersion of the rotor in a bath containing a chemical machining agent, the bath having a capacity of heterogeneous material removal (as a function of the depth of the bath), the rotor being oriented in the bath taking account of the said capacity of heterogeneous material removal so that the quantity of material removed from the rotor in the zone of the unbalancing mass is sufficient to balance the rotor.
