Vertical axis balancing machine for rotors with a mass of up to 50 kg, equipped with 3 controlled axes X-Y-Z milling unit for automatic compensation of the unbalance on one or two planes. The machine has been designed specifically for the dynamic balancing of various types of pump impellers. It is in fact possible to perform milling on the rotor blades with horizontal axis milling tool, or circular shape milling with vertical axis milling tool, or following the blade profile. A laser device is used to detect the real position of the blades before the unbalance correction.
The balancing cycle is totally automatic, and if needed, unbalance measurement and compensation are done more than once until the unbalance values are below the programmed tolerances.
