- Simple, safe handling and small space requirement
- Balancing in one or two planes
- No calibration runs required due to permanent calibration
- High measurement accuracy through digital processing of measurement values
- Protective shrouds according to SAE standards
Design
Force-measuring vertical balancing machine with permanent calibration and manual operating sequence.Welded machine housing, balancing unit formed as a dynamometer system, with highly sensitive electro-
dynamic transducers, precision balancing spindle and drive motor.
Control cabinet with operating elements and microprocessor measuring unit, protective shroud according
to ISO 7475.
Range of application
Measurement and correction of unbalance in one or two correction planes in individual compressor and turbine discs, spacers, etc. for jet engines.The series VE is designed for rotors that need to be balanced in only one plane.
These machines are used in manufacturing and overhaul workshops. Simple change over to other rotor
types by exchanging tooling adapters and selecting the respective stored rotor file.
Manual unbalance correction in or out of the machine.

Vertical, force-measuring balancing machines series V are specially designed for balancing compressor and turbine discs, seals, spacers, etc. for jet engines in one or two correction planes.The accuracy and large operating range of Schenck RoTec machines permits many balancing tasks to be covered by one machine, reducing the handling costs and increasing efficiency. -
For jet engine rotors that are balanced in only one plane the VE series is the cost-effective solution.The vibration system here also operates according to dynamometer principles and permits permanent calibration of the measuring unit and high balancing accuracy.
