Balancing Machines for Turbocharger Turbine Rotors

  • Automatic balancing
  • Short cycle times with extremely high initial unbalance
  • Air-bearing support for extreme measurement accuracy
  • Digital measured data processing and numerically controlled unbalance correction
  • Effective milling correction in machining center
  • Easy change over to other rotor types

Range of application

Measurement and correction of unbalance in machined turbocharger turbine rotors. Use of the machine in mid- to high-volume production. Fully automatic unbalance measurement and correction in two planes and in up to two correction steps. Manual loading and unloading.


Two-station machine with measuring and correction station and fully automatic operating sequence. Vertical balancing unit on a vibration-optimized machine frame of aluminium profile, type-dependent, exchangeable precision air-bearing support for the turbine rotor, drive through a drive-plate with air-jet adapted to the rotor diameter.
Measured data processing by CAB 750 measuring unit.
Correction station configured as a vertical traversing-stand machining center, with CNC machining unit for unbalance correction by polar milling on the hub-side and at the rear of the turbine rotor. Integrated tool changer with 12 tool positions.

Sequence of operations

  • The work-pieces are removed from the conveying equipment, provided with a reference mark and inserted into the measuring station
  • Automatic measuring run. Calculate and transfer the processing values to the correction station, brake to a stop
  • Remove the rotor from the measuring station and load it into the correction station, align the reference mark
  • Automatic correction: clamp, select the right correction tool, index to the correction position and mill the 1st plane. Index to the correction position for the 2nd plane, repeat the milling process and unclamp
  • Transfer the rotor to the measuring station and start the check run. If the unbalance after the 1st correction step is not in tolerance, a 2nd correction step can be carried out
  • Remove the work-piece and place it on the conveyor
