Precision Shop Balancing
Master Precision Rotor Balancing in the Workshop

The LGP Institute Precision Shop Balancing Course is designed for technicians, engineers, and balancing specialists who perform rotor balancing using professional balancing machines in workshop environments.

This course provides a practical understanding of rotor unbalance, balancing methods, correction techniques, balancing tolerances, and the correct use of shop balancing equipment.

Participants will learn how to identify unbalance conditions, select the correct balancing method, determine correction planes, calculate correction weights, and verify final balance quality according to international practices.
