Production Spin Testing & Balancing Services

Test Devices provides production spin testing and balancing services of production parts for customers with a repetitive need and who demand schedule predictability along with a quick turn-around time. Whether proof testing critical rotating components before shipment, pre-spinning to achieve required rotational growth prior to finish machining or simplifying the supply chain by consolidating pre-spin with rough machining and/or NDT inspection, Test Devices offers a full range of spin testing solutions.

Balancing Services

Test Devices employs soft and hard bearing balance equipment to properly balance rotating components prior to spin testing. In-pit, at speed balancing within the vertical spin chamber is also available for higher speed applications.

Overspeed / Proof Testing

With a dedicated machine and a two shift operation, Test Devices offers quick turnaround on repetitive spin/balance operations for single components or multipart lots. Tool Design, including rotor-dynamic and stress analysis, is also available.

Tooling & Arbors

Precision design, analysis and manufacture of spin tooling (fixturing) are critical to effectively spin test complex, highly stressed, rotating components. Test Devices’ engineers utilize extensive experience, three dimensional modeling and analysis software to ensure spin tooling meets customer requirements.

Rotational Pre-Growth

Test Devices is ISO9001, AS9100 certified and approved by several major engine OEM’s to perform production pre-spin operations of rotor forgings in advance of final machining. Additional services and adjacent operations can be performed in-house or arranged for to provide a convenient supply chain consolidation solution.

Developmental Pre-Spins

When new designs or materials are being introduced, more thorough test data is often required to validate predicted growth models. Test Devices can measure elastic and plastic radial growth of components in real time while rotating. This technique can verify stress and growth models and determine precise gaps between rotating and stationary components in turbomachinery.

Drug and Alcohol Testing Program

Processing of repaired and overhauled rotating parts often require an overspeed spin test be performed by a vendor with a drug and alcohol testing program that meets the requirements of DOT Regulation 49 CFR parts 382 & 40. Test Devices has a compliant program in place.
