At the heart of the balancing machine is the measuring system. AHC incorporates piezo electric force measuring transducers into a compact, high output, two plane measuring table. This measuring table can be mounted either in a horizontal or vertical configuration and is available in four standard sizes and special sizes as needed. This design achieves measurements accurate to five microinches (0.13 um).
Tooling includes non-rotating arbors for compressor wheels, bushings for wheel and shaft assemblies, and V-blocks for rotor assemblies or for balancing a complete core in it's own bearings. The rotor is typically driven by a closed loop servo controlled air drive system. Available automatic correction options for high speed applications include CNC controlled milling and high speed CBN grinding.
