A measuring machine comprising a measuring column, which can move vertically with respect to a carriage, and a device for balancing the weight of the column, which is provided with a pneumatic cylinder having its liner fixed to the column and the stem constrained to a supporting structure, carried by the carriage via an elastic-suspension assembly that enables the stem to follow the liner in the case of adhesion and to return into a position of equilibrium when the elastic reaction of the elastic-suspension assembly overcomes the force of friction between the piston and the liner; stick-slip phenomena are thus neutralized. |
