Precision gears for aerospace applications

CIMA manufactures precision gears and transmission components for aerospace applications, including helical and spur gears, shafts, splined components and other high-accuracy parts. Components are produced according to customer drawings and specifications for applications such as turbofan accessory gearboxes, flight actuation systems, propulsion transmissions, tail rotor drives, rescue hoists and other auxiliary critical applications.

Manufacturing is supported by in-house gear cutting, machining, heat treatment and non-destructive testing, with control of gear geometry, dimensional tolerances, surface characteristics and material properties throughout the production process which is compliant with EN9100 and NADCAP accreditations. In-house heat treatment and inspection capabilities allow CIMA to manage critical parameters such as case depth, hardness and metallurgical structure, while maintaining process traceability and documented inspection results from prototype through series production.
