Balancing Machine for Turbocharger Rotors MBBS

Range of application
Determining the unbalance in machined turbocharger rotors. Use of the machine in the production of small- and mid-volumes, for quality control and research and development.

Unbalance measurement in two planes, programmable conversion of the unbalance to the most suitable correction planes. Unbalance correction by an optional correction unit in multiple correction steps. Loading and unloading manually or by hand-operated device.

Design
Machine with vertical axis, between one and three balancing units and an automatic operating cycle.

Vibration-optimized machine frame of aluminium profile.

Type-dependent, exchangeable precision air bearings. Drive with automatic speed control and special drive-plate with air jet adapted to the rotor diameter.

Automatically operating pneumatic lifting device to facilitate loading.

Measured data processed by measuring unit CAB 750.

Precision air bearings – such as the version for a compressor rotor shown here - take care of clearance and offer wear-free support of the rotor. The drive by air-jet is fast and prevents measurement errors.

The balancing unit is provided with a device for gentle loading and unloading on the air-bearings.

Various balancing units (up to 3) can be combined for fast balancing of a wide range of turbocharger rotors without requiring costly change over.
