YEARS IN BUSINESS
CURVIC COUPLINGS PRODUCED
We are a full-service precision machining facility with major OEM approvals. We support aerospace, defense, and industrial OEMs and Tier 1 suppliers across the world. We have been AS9100 registered since 2005 and are a Nadcap accredited supplier for Conventional Machining as a Special Process.
Because the manufacturing of Curvic couplings requires a highly specialized, unique grinding technique with extreme accuracy, expertise in the process is paramount. Curvic couplings resemble face gears, but the teeth are curved in both the radial and axial directions. Concave and convex Curvic couplings mate together, creating intricate interlocking assemblies that can withstand high powered operating environments while maintaining a precise centerline axis of rotation. As such, a superior level of engineering expertise along with unique machinery are required to effectively produce Curvic couplings.
We have manufactured Curvic couplings for over 40 years and are the world leader in the technique. Our team has over 100 years of collective experience in Curvic manufacturing making us the industry’s undisputed experts. This deep expertise and singular focus enable us to manage difficult situations and be the best in on-time delivery.
