Single Station Pump Impeller Balancing Machine Automatic Milling Correction Balancing Machine
The Single Station Pump Impeller Automatic Balancing Machine with Milling Correction is engineered for high-precision dynamic balancing and automatic correction of stainless steel pump impellers. It is suitable for impellers with diameters ranging from Φ160 mm to Φ500 mm and performs balance correction through an advanced beveled milling process.
To ensure maximum machining stability and precision, the system is equipped with a BT50 power spindle. Its high-rigidity design minimizes vibration during the milling operation, enabling accurate material removal and consistent balancing performance.
The machine integrates several key systems into a single automated solution, including a dynamic balancing unit, automatic milling correction system, dust extraction unit, control cabinet, power cabinet, and electrical control components. The balancing mechanism features an internally actuated pneumatic expanding fixture that securely holds the impeller while providing excellent centering accuracy, dependable clamping force, and quick loading and unloading.
A precision taper-fit design between the mandrel and expanding sleeve enhances alignment accuracy, while a self-locking pneumatic clamping cylinder ensures the workpiece remains firmly secured even in the event of an unexpected air pressure loss.
The automatic correction system combines an axial tool feed mechanism with a rotary arc positioning system to achieve precise material removal. During operation, the machine measures the rotor's unbalance and automatically converts the measurement data into milling correction parameters. A PLC-based control system then performs the balancing process without manual intervention. The axial feed mechanism precisely regulates the cutting depth, while the three-jaw chuck accurately positions the milling angle, ensuring efficient, repeatable, and high-accuracy balance correction for every impeller.
