Powerful balancing solutions for complex requirements

We provide comprehensive solutions, including specialized tooling, for all jet engines – including industry-leading models such as the Leap, CFM56, Pratt & Whitney GTF, and Trent.

Efficiency and durability in balance

Profitability starts with the right balance. Our balancing machines and moment weighing scales, combined with the Bladis 4 software, reduce vibrations in engine rotors increasing the longevity and efficiency of engine. Schenck Tooling offers innovative solutions for the precise handling of components, modules, and assemblies, including rotors from stationary gas turbines.

Precisely measured and flexibly expandable

Our horizontal balancing machines for turbines and compressors comply with SAE ARP 4048 standards and are flexibly expandable helping you meet current and future requirements. When balancing compressor and turbine discs or spacer rings for jet engines, you benefit from the high measurement accuracy of our vertical balancing machines with permanent calibration and options for balancing in one or two planes.

Moment weighing scales with new generation precision

The new generation of our moment weighing scales optimizes the blade distribution on rotors by precisely measuring the mass and torque of engine blades. They comply with SAE ARP standards and offer a wide range of options to meet the current and future needs of the aerospace industry.

Moment weighing scales WM(E)

Our moment weighing scales for engine components (WM and WME series for engine blades) enable highly accurate determination of radial, axial, and tangential moments. They operate according to the force measurement principle, are permanently calibrated, and are insensitive to temperature fluctuations. The special friction-free and backlash-free mounting design of the measuring arms ensures they operate wear-free and with high accuracy regardless of the component weight.

• Maximum weight: up to 200 kg
• Measurement duration: 2 s to 5 s
• Radial torque: from 0,02 kgm to 14 kgm
• Sensitivity: from 0.1 gmm/kg to 500 gmm for blades up to 20 kg

Machines for determining mass properties

The precise determination of unbalance, center of gravity, and moments of inertia is essential for optimizing the attitude control of satellites in space and their transport. Satellite balancing machines help bring satellite unbalances within tolerance, rotating tables measure the moments of inertia before launch, and center of gravity scales precisely determine the center of mass. Schenck machines enable precise analysis of the mass properties of aerospace systems, components, and payloads.

Tooling

Tooling for aviation and aerospace

Tooling for balancing and moment weighing:

Optimal results in terms of accuracy and throughput time can only be achieved if the machine and rotor tooling are carefully matched. In addition, the respective task and specific requirements must be taken into account. We offer complete tooling packages for moment weighing as well as horizontal and vertical balancing. Customers receive solutions for their balancing tasks from a single source, as Schenck offers both balancing machines and tooling. The modular tooling concept allows easy adaptation to different balancing machines, both current and older models.

Our CAB 925 and Bladis 4 feature the intelligent measurement system for precise balancing in aerospace.

Software solutions for the aerospace industry

Precise measurement systems are crucial in the aerospace industry – for rotor balancing, blade mass distribution, and determining mass properties. Accurate measurements minimize vibrations, ensure aerodynamic efficiency, and guarantee stability, thereby increasing the service life of systems. Reliable measurement systems are indispensable for meeting the highest safety standards.

CAB 925 for maximum precision

CAB 925 is our solution to the specific requirements of balancing in the aerospace industry and is intuitive to operate, powerful, and highly precise enabling fast and safe work with minimal training required, and that for all relevant rotor variants. This is ensured by its robust design, which is perfectly adapted to its intended use.

About the CAB 925

Bladis 4 for optimal blade distribution

The Bladis 4 software, in conjunction with our moment weighing scales, ensures the optimized distribution of weighed blades across compressor and turbine stages. The advantages: in the best-case scenario, the unbalance can already be within tolerance by redistributing the blades, eliminating the need for additional balancing steps.
