Acoustic Testing and Balancing Machines

A precisely controlled air pressure drive accelerates and decelerates the turbocharger core assembly to about 80% of the final speed it will achieve in the motor. The unbalance of the turbocharger is precisely measured over the complete speed range, even at 300,000 rpms per minute.

During the run-up the vibration of the components is measured and the unbalance for two correction planes is determined. By milling off material on the compressor wheel and on the shaft nut, the unbalance is corrected quickly and precisely.

Balancing turbochargers achieves a residual unbalance of only a few mgmm, so that once installed in a car, the turbocharger enjoys a long and quiet service life.
