Aerospace Tube Bending Procedure

  • Developing and Creating – Specialized computer-aided design (CAD) software converts the intended tube bending specifications into a digital format.
  • Tube setting up – After the pipes or tubes have been cut to the correct length, their ends must be clean.
  • Getting Safe –  The opposite end of the tube is securely secured, leaving the other end free for bending.
  • Drawing Out – After carefully positioning and bending the tube around a form die or mandrel, the CNC machine applies controlled force.
  • Maintaining Excellence – To ensure the final output satisfies the requirements, errors, and variances are fixed.
