Hard Bearing Balancing Machine Technology - Proper Use of Rotor Type-Specific Calibration
AIR6975
The scope of this SAE Aerospace Information Report includes practical applications, theory, process management, audit and control recommendations, recommended validation intervals, verification and validation, file setup parameters, additional considerations, and process documentation.
Rationale:
Modern hard bearing balancing machines employ computer-based measuring units that permit optimizing and adjusting the measuring result to reflect unusual conditions that would otherwise complicate measurement results and impair the balancing process. Hard bearing balancing machines feature a “permanent calibration” that is suited for a wide variety of common rotor configurations. However, certain rotor balancing configurations operating under challenging conditions require special compensation to achieve unbalance tolerances as quickly and as accurately as possible. The purpose of this report is to inform and instruct the reader in the proper application and use of unique adjustments to obtain accurate measurement results as quickly as possible.
