CNC machining delivers micron precision and tight tolerances for complex geometry.
Optimized for mass production, high-volume machining utilizes advanced automation and process control to ensure consistent quality, tight tolerances, and superior cost efficiency at scale.
Designed for precision-driven applications, low-volume machining supports prototype development and limited production runs with high accuracy, rapid iteration, and reduced tooling requirements.
This ensures accurate control surface deflection and minimizes elastic recovery, which is especially critical in high-frequency environments like UAV rudders or supersonic stabilizers, where precision and stability are paramount.
Cross-sectional geometry is selected based on fatigue-critical regions observed through FEA under repeated flap or elevator actuation. Control surface hinge pins are processed from vacuum-melted alloys with a high endurance limit and fine-grain structure, minimizing initiation points for microcracks. Edge transitions and fillets are CNC-ground to sub-micron smoothness to avoid geometric stress risers at the pin-shoulder junctions.
Surface treatments such as nitriding, cadmium plating, or PVD coatings are applied based on operating climate and contact material. These treatments inhibit oxide formation while maintaining low surface roughness to minimize abrasive wear against bushings or needle bearings. Diffusion layers are engineered for minimal thickness deviation to preserve interference fit integrity during long-term environmental exposure.

Transfers hinge loads in elevator and rudder systems, ensuring fatigue resistance during cyclic pitch and yaw maneuvers.
Provides rotational alignment and shear load transfer between control rods and pitch links in variable-angle tail rotor systems.
Supports compact actuation hinges with micro-clearance fits to prevent flutter in lightweight, high-frequency deflection environments.
Withstands extreme dynamic pressure and thermal expansion loads on elevons and ruddervators in supersonic flight regimes.
Maintains precise deflection in control surfaces during repeated high-g maneuvers typical in aerobatic and combat training profiles.
Transmits actuation loads through high-strength hinges during aerodynamic steering phases in suborbital or re-entry flight conditions.
Retaining mechanisms such as precision-ground grooves, circlip seats, or through-hole configurations are integrated based on hinge assembly design. Shear transfer zones are calculated for optimal engagement with control horn and bearing housing without introducing bending moments that may induce lateral displacement. High-strength stainless steels or maraging alloys are selected to accommodate combined axial and torsional loads under actuation.
Concentricity between shaft axis, head geometry, and retaining features is held within 0.005 mm to ensure balanced load transfer across bearing faces. This uniformity eliminates eccentric wear patterns, particularly in asymmetrically loaded control surfaces like rudder-vator assemblies. Concentric pin design also simplifies modal analysis for vibration-sensitive control modules.

Frigate uses precision CNC turning and grinding processes to maintain concentricity within ±0.005 mm between shaft, head, and groove features. This avoids asymmetric loading on control surface bearings, which can cause uneven wear or hinge binding. Every pin undergoes CMM inspection for geometric accuracy. This ensures stable actuation and consistent load paths under dynamic flight conditions.
Frigate conducts fatigue testing that simulates high-cycle actuation environments using servo-hydraulic test rigs. These tests verify resistance to crack initiation and propagation under combined shear and bending loads. Material and coating integrity are also evaluated after the cycle tests. This helps ensure the control surface hinge pins maintain mechanical integrity across extended operational life.
Frigate selects coatings such as cadmium or zinc-nickel plating to prevent galvanic reactions with aluminum or titanium hinge arms. Each coating is applied to controlled thicknesses to avoid dimensional distortion. Compatibility is verified through salt spray and galvanic current testing. This protects against electrochemical corrosion in mixed-metal assemblies.
Frigate offers design variations including through-hole locking, external grooves, and captive collars based on the customer’s hinge housing architecture. Retention features are analyzed using FEA for stress distribution under vibrational loads. Material hardness and groove depth are optimized to prevent wear during oscillation. These designs are validated through mechanical pull-out and endurance testing.
Frigate provides hinge pins with high dimensional repeatability and smooth finishes for seamless robotic installation. Tolerance stack-up is minimized using GD&T-driven machining workflows. Pins are supplied with batch-specific inspection data and serialized tracking. This allows direct integration into automated fixtures with minimal handling or secondary alignment processes.
