440 KBTU Transfer Balancing Machine for Wound Armatures

Product catalog summary

Field of Application: The document describes a system for measuring and correcting the unbalance of wound armatures and rotors of various sizes, primarily used in fully automatic production lines with high production rates. The correction is achieved through milling in one or two planes.

Correction Procedure: The system employs slot milling in components, vectorial distribution of measured unbalance to pole heads, profile milling, and polar unbalance correction directly at the determined angular position. Polar slot milling is achieved by axially adjusting the milling spindle equipped with double slot milling cutters.

Integrated Overhead Rotary Transfer Machine: The machine operates fully automatically with NC axes for all movements and can be linked with production lines. It features a powerful measuring unit, CAB 850, based on an industrial PC.

Special Features: The machine offers high-speed rotor transfer with overhead rotary transfer at a small operating radius, shock-free transfer due to sinusoidal movement, and grippers with damage protection. The correction station includes a digitally controlled milling and positioning device, with a cutter touchpoint signal. The milling procedure can be selected without modifying control, and swarf is extracted from below. The system is flexible, easy to retool, and supports fast troubleshooting.

Important Data: The machine types 441 KBTU, 442 KBTU, and 443 KBTU offer different unbalance correction methods, including polar profile milling, slot milling in components, and polar slot milling. Cycle times vary depending on the correction plane, with retooling times ranging from 5 to 15 minutes. Achievable residual unbalance is less than 3 gmm/kg depending on the rotor.

Set-up Example: A 4-station machine with fully automatic functions is described, including transfer, measuring, correction, and checking stations, along with a control cabinet, measuring system, positioning control, and swarf extractor.
