  1. The Pipe Is Clamped<\/li>\n<\/ol>\n\n\n\n

    The straight pipe or tube is placed into the machine and held tightly by:
    Clamp die
    Pressure die
    Bending die
    Mandrel
    This prevents slipping during bending.<\/p>\n\n\n\n

      \n
    1. The Bend Die Rotates
      A round bending die rotates and pulls the pipe around its radius.
      This creates the bend angle:
      45\u00b0
      90\u00b0
      180\u00b0
      custom angles
      The bend radius depends on the tooling size.<\/li>\n\n\n\n
    2. Mandrel Support (Optional)<\/li>\n<\/ol>\n\n\n\n

      For thin-wall tubes, a mandrel is inserted inside the pipe.
      The mandrel helps:
      prevent collapse
      reduce wrinkles
      maintain roundness
      This is important for:
      automotive exhaust pipes
      furniture tubes
      aerospace tubing
      hydraulic tubes<\/p>\n\n\n\n

        \n
      1. CNC Control System
        Modern CNC pipe bending machines use computer control to automate:
        bend angle
        rotation
        feed length
        multiple bends
        The operator inputs the program, and the machine performs repeatable bending automatically.
        Typical CNC axes include:
        Axis Function
        Y Feed pipe length
        B Rotate pipe
        C Bend angle<\/li>\n\n\n\n
      2. Finished Bent Pipe
        After bending, the finished part may be used in:
        automotive parts
        furniture
        construction
        HVAC
        medical equipment
        shipbuilding
        aerospace<\/li>\n<\/ol>\n\n
