Balancing Technology

Parts such as turbo chargers can be balanced very acurately with acoustic balancing.

Balancing turbochargers for automobiles is necessary, because all bodies turning around their axis have a certain unbalance. This results in vibrations that can lead to higher wear and loss of performance.

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.

Development and Analyses

We are happy to support you with product development. We offer modal analysis of your core assemblies and their individual parts, such as rotor or housing. We do conduct measurements during the running process on site, individual parts are measured in our test lab.

The collected results from the analyses will be used for improvements of your products. We provide a full set of measuring data.

 

Sensor Calibration

We offer regular calibration of the acceleration sensors for our machines. This can be done on site to minimize down times.

We do provide you with the respective calibration certificates and we also compile a data base with the current calibration data of all sensors. Over time you gain valuable insights about the service life and mechanical load of the individual sensors.
