Challenge: Under the lightweight‑weight requirement for drones, thin‑walled aluminum alloy brackets are prone to deformation during CNC machining, compromising structural strength and assembly accuracy.
Drones are designed for extreme lightweight performance, so thin‑walled aluminum alloy brackets are widely adopted. In conventional CNC machining, cutting heat and clamping force tend to trigger micro‑deformation or residual stress in thin‑walled parts, which undermines the structural strength and installation accuracy of finished products. By adopting specially customized fixtures, multi‑axis linked low‑stress cutting strategies and optimized precise tool paths, we keep machining‑induced deformation within 0.008 MM.
Challenge: Drones are subject to continuous high‑frequency vibration during flight, and dimensional deviations of connecting components may cause thread loosening or structural resonance.
During drone flight, bracket connectors endure prolonged high‑frequency vibration and impact. Poor dimensional accuracy and fitting stability of connectors may result in screw loosening, structural resonance and even flight‑safety hazards. We implement full‑process SPC (Statistical Process Control) and high‑precision inspection with Zeiss coordinate measuring machines to guarantee that the CPK value of critical fitting dimensions for mass‑produced parts exceeds 1.33.
