CNC Machining for Aerospace Landing Gear Components

The landing gear system is one of the most critical and heavily stressed components in any aircraft. It is responsible for supporting the entire weight of the aircraft during ground operations and absorbing immense impact forces during landing. The failure of a single part can have catastrophic consequences. Therefore, the manufacturing of aerospace landing gear components demands an unparalleled level of precision, reliability, and material performance. This is where advanced CNC (Computer Numerical Control) machining becomes indispensable.

Modern 5axis CNC machining is at the heart of producing highintegrity landing gear parts such as pistons, rods, trunnions, and braces. These components are typically machined from ultrahighstrength materials like 300M steel, titanium alloys (such as Ti6Al4V), and precipitationhardening stainless steels. These materials offer an exceptional strengthtoweight ratio but are notoriously difficult to machine. A specialized CNC partner understands the exact cutting parameters, tooling strategies, and cooling techniques required to process these materials without inducing surface stresses, microcracks, or thermal deformation that could compromise the part's structural integrity.

Beyond material expertise, precision is nonnegotiable. Landing gear components feature complex geometries with tight tolerances, often within microns. CNC machining ensures that every contour, bore, and thread is produced with repeatable accuracy, guaranteeing perfect fit and function within the larger assembly. This precision is critical for the hydraulic systems within the landing gear, where seals must function flawlessly under extreme pressure.

Furthermore, a fullservice CNC provider offers comprehensive support beyond just milling and turning. This includes:
Secondary Processing: Essential treatments like shot peening to induce compressive surface stresses, enhancing fatigue life.
Heat Treating: Precision hardening and tempering to achieve the required material properties.
