Landing gear mounts

Titanium alloy

Landing gear mounts are complex structural components that are situated horizontally in the wing structure above the landing gear. These elements connect the wing and the landing gear and act as a shock absorber in conjunction with the main cylinder of the landing gear.

These are solid forged components with numerous 3-axis and 5-axis pockets, and mainly consist of titanium alloys. Machining titanium produces high temperatures at the tool cutting edge. Uncontrolled heat transfer creates tension in the component that can subsequently cause it to warp, even after weeks have passed. This means that optimum cooling for machining operations, controlled chip evacuation and high-quality clamping devices and tools are crucial for ensuring process reliability
