Balancing Services

Unbalance in rotating components could lead to a catastrophic failure and result in threats to machinery and personal safety.

Despite its apparent simplicity, precisely balancing a rotor requires a subtle yet absolute expertise. Not all balancing service providers are “equal”, and capable of performing the necessary level of quality and consistency in their work. Improper or insufficient balancing can cause even more issues, all of which resulting in higher overall costs. To learn more, read our E-Book "Balancing 101: What you should know about balancing your rotating part" for more information.

  • Balance tooling design

    Balance tooling design

    A balancing job is only as good as the tooling used to perform it. Well-designed tooling should provide a precisely-machined shaft surface to mount the rotor onto the balancing machine, and a purpose-designed mechanism to accurately interface the shaft with the rotor in an accurate and repeatable manner. This detail is often overlooked by customers who are not familiar with balancing processes.

  • Engineering support

    Balancing is not an art—it is a science and an engineered process. Correctly installing the balancing machine, calibrating the measurement, and performing a repeatable and accurate unbalance measurement are crucial steps before any unbalance correction can be performed. The methods and operational steps in unbalance correction must be implemented with a full understanding of the damage sensitivity and operation-critical features of the parts to avoid damage and mishandling.

  • Quality assurance

    Quality assurance

    All planned balancing processes should be double checked by trained members of the quality assurance department, as should all completed balance corrections. This is particularly important for work that involves safety and operation-critical rotating components, as even the slightest mishandling can lead to serious consequences.

  • Balance budget analysis

    Balance budget analysis

    The effect of the geometric tolerances of given parts are analyzed and the influence on the imbalance of the rotor is estimated using a mathematical model to simulate the manufacturing process, while also comparing more than 10,000 different combinations of tolerance variations. The output from this analysis provides a probabilistic model of the imbalance in the rotor, which can be used to tune the design, minimize scatter, and avoid surprises in your fabrication processes.

  • Precision Machining

    Precision Machining

    Some balancing work may require very delicate and precise material removal where manual grinding with hand tools is not appropriate. TDI is equipped with state-of-the-art CNC mills and has an expert machinist ready to serve your needs.

Over-Speed Spin Testing

Manufacturing processes for some high-speed components require both balancing and over-speed spin testing prior to final installation. Test Devices provides a full range of spin testing services with a quick turnaround.

Balancing Services

Drawings for many precision parts call out very precise depth and width levels, below which material cannot be removed. To ensure compliance to these requirements, for many precision balanced parts, Test Devices includes a final measurement verification step performed by our quality department.
