Five-Axis CNC Machining of Aluminum 7075-T6 for eVTOL Structural Components
Date: July 10, 2026 Category: Aerospace / CNC Machining Author: HasunCNC Technical Department ---The Weight-Strength Optimization in Low-Altitude Economy
The rapid growth of the "Low-Altitude Economy" (eVTOL - Electric Vertical Takeoff and Landing) has placed unprecedented demands on structural components. Every gram saved translates directly into flight range, while every micron of precision ensures the safety of urban air mobility.
At HasunCNC, we have standardized the production of Aluminum 7075-T6 airframe connectors and motor mounts, utilizing ultra-high-speed 5-axis machining to meet the rigorous standards of the aerospace industry.
Why Aluminum 7075-T6 for eVTOL?
7075-T6 is the "Workhorse" of aerospace, offering a strength-to-weight ratio that competes with steel while being significantly easier to machine into complex, aerodynamic geometries.
> Expert Insight: "In eVTOL manufacturing, the transition from 3-axis to 5-axis machining isn't just about complexity; it's about reducing setup errors and ensuring that grain orientation in 7075-T6 is optimized for structural load paths." —*Chief Engineer at HasunCNC*

Precision Challenges in 7075 Machining
1. Residual Stress Management
7075-T6 is prone to warping during heavy material removal. We employ Sub-zero Cryogenic Stabilization and specific tool path sequencing to ensure that thin-walled eVTOL brackets remain dimensionally stable within ±0.01mm.
2. High-Speed Surface Integrity
To achieve Ra 0.4μm without post-polishing, we utilize high-feed cutters with DLC (Diamond-Like Carbon) coatings, reducing friction and preventing "built-up edge" (BUE) during the high-RPM finishing passes typical of aerospace parts.
