Vertical axis balancing machine for pump impellers with a mass of up to 200 kg, equipped with double correction unit:
- One three controlled axes X-Y-Z milling unit for automatic compensation of the unbalance on one or two planes
- One two controlled axes X-Z drilling unit for automatic compensation of the unbalance on one plane.
The milling unit is used to perform milling on the rotor blades with horizontal axis milling tool, following the blade profile.
A laser device is used to detect the real position of the blades before the unbalance correction. The drilling unit is used to perform controlled depth holes on the impeller hub. The balancing cycle is fully automatic and can be performed only by milling, only drilling or both.
The choice of the type of correction is done automatically by the machine, according to the measured unbalance amount.
