Balancing machine for turbocharger compressor and turbine wheels Xano

Patented air bearing rotor support for extreme measurement accuracy
Short run-up and braking times through air-drive
Measuring equipment with digital measurement and direct unbalance or correction display
Easy change over to other rotor types

Design

Machine with vertical axis, one or two balancing units and an automatic operating cycle.
Vibration-optimized machine frame.
Type-dependent, exchangeable precision air bearings. Drive with automatic speed control and special drive-plate with air jets adapted to the rotor diameter.
Automatically operating pneumatic lifting device to facilitate loading.
Data processed by measuring unit CAB 950.

Design

Range of application

Determining the unbalance of 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. Unbalance correction by an optional correction unit in multiple correction steps. Loading and unloading manually.
