Torque Tubes
LeFiell has a unique combination of capabilities that provide industry-leading solutions for Torque Tubes commonly used in aircraft passenger door and cargo door applications. They are usually made from CRES or titanium bars requiring high strength and stable properties and require very precise finish OD/ID tolerances and straightness for close fit and function to meet the exacting standards of our aircraft structure customers.
The parts can be very long and often have specialized surface treatments applied such as Passivation, CAD Plating, and various primers and paint. They transmit rotating power within the complex and precisely assembled mechanical mechanisms and must operate smoothly without failure for many years. LeFiell employs a combination of capabilities such as Gundrilling, Honing, Roll-Flo®, Close Tolerance Turning, Boring, Straightening, and Thermal Treatments to achieve very demanding tolerances. LeFiell's industry-leading supplier partners provide the specialized coatings required for our finished goods.
