Case Study

Aluminum aerospace bracket case study

Aluminum Aerospace Bracket

Client Challenge: A leading aerospace manufacturer needed a lightweight aluminum aircraft bracket, which required strict tolerance control to avoid deformation during flight, with thin wall sections of 0.5mm that was prone to machining stress deformation.

Our Solution: We optimized the custom fixture design to reduce clamping stress, adopted 5-axis machining to complete the part in one setup, and adjusted high-speed cutting parameters to minimize material stress release during processing.

Project Result

  • Achieved strict tolerance of ±0.005mm, fully meeting aerospace requirements
  • Part deformation controlled within 0.02mm, solved the client’s deformation issue
  • Production yield reached 99.2% *Data for reference only
  • 15% weight reduction compared to the client’s original design
