Between the infinite starry space and the free sky lies humanity's never-ending quest for aerospace. Achieving this pursuit is the labor of millions of precise, reliable, and meticulously designed components. Of these components are precision mounting brackets, seemingly unimportant at first, which are the silent guardians that ensure safe and stable functioning of important equipment—the most crucial organ of an aircraft—the engine, avionic systems, actuation systems, and more. Their quality has a direct effect on the performance and safety of the whole airplane. This article will explore CNC milling technology, the backbone of producing aerospace-grade precision mounting brackets, and how LS, by virtue of its outstanding CNC machining capabilities, has emerged as a go-to partner in the industry.

Mission Critical: Why are precision mounting brackets so critical?

The demands placed on components in the aerospace business are leading-edge industrial manufacturing. Each mounting bracket has a specific mission:

• Rigorous structural stiffness and strength: They must maintain form and functional integrity under rigorous vibration, high acceleration, and extreme temperature changes to prevent the catastrophic consequences of resonance.
• Optimal light design: "Optimize every gram" is the aerospace golden rule. Brackets must balance weight reduction with complex topological optimization and material cutting while focusing on maintaining strength.
• Perfect precision and uniformity: Inaccurate mounting hole placement, flatness, and coaxiality by small design deviations can lead to system misalignment, add unnecessary stress, impact overall performance, and even cause failure.
• Excellent material properties: Aluminum alloys with high strength, titanium alloys, and nickel-based alloys for high temperatures are widely used as specialty materials. These have very strict properties such as light in weight, high strength, corrosion resistance, and high-temperature resistance.

For this reason, traditional manufacturing procedures are not capable of meeting these requirements, and high-precision CNC milling technology has become the only choice for producing such parts.

Core Technology: How CNC Milling Provides Aerospace-Grade Precision

Computer numerical control, or CNC, machining, particularly multi-axis CNC milling, is a staple of modern-day aerospace manufacturing. It uses computer numerical control to translate 3D design models into actual, accurate parts with precision to millimetre-to-millimetre accuracy.

1. Five-Axis Simultaneous Milling: The gold standard technology for manufacturing complex-shaped brackets. Five-axis CNC machines involve two rotational axes on the three linear X, Y, and Z axes so that the tool can approach from any direction. This means that nearly any surface can be machined within one setup, thus ensuring very high machining accuracy and surface finish and eliminating the cumulative errors associated with multiple setups. It is thus particularly well-suited for machining custom parts with highly curved surface shapes.
2. High-Speed ​​Milling (HSM): Utilizes high speeds, low depths of cut, and high feed rates. High-Speed ​​Milling results in a dramatic reduction in cutting forces and workpiece deformation, critical to light-weight brackets with thin-walled configurations, while simultaneously providing improved surface finish.
3. Computer-Aided Manufacturing (CAM) and Simulation: Even before any blade touches metal, LS engineers utilize advanced CAM software to develop thoroughly programed and simulated designs. The process optimizes tool paths, anticipating and avoiding possible collision, overcuts, and undercuts to ensure a guaranteed machining process and protecting expensive aerospace materials.
