Tube Bending with Crippa Machine

Mechanical process. Complex forms. Accuracy.

CNC Tube Bending

CNC tube bending is a mechanical process of metal working. Flat tube is inserted into machine and is brought into desired shape by pushing the thorn with one or more curves. This process is used for creation of complex tube forms from different types of materials. Tube bending is influenced by many factors, such as quality of the material, thickness of the pipe wall, quality of tools and lubricants.

For bending tubes we use Crippa Linear CA 563 machine. It is suitable for use in the furniture, automotive as well as aerospace industries. This machine has five axes and is fully CNC controlled, and driven by digital electrical motors. Maximum diameter of tube bending is 60.3 mm and usable length of the tube is 5500 mm. The machine can also bend products, which have a variable angle with option of bending into helix.

FAQ

  • What machine do you use for CNC tube bending?
    We use the machine Crippa LINEAR CA 563.
  • Can the tube get deformed when bent with a thorn?
    Yes, if the quality of the tube is not suitable for bending.
  • What tubes’ diameters can you bend?
    We can bend tubes with diameters: ∅15 mm, ∅18 mm, ∅20 mm, ∅22 mm, ∅25 mm, ∅26.7 mm, ∅28 mm, ∅33.7 mm, ∅40 mm, ∅42.4 mm, ∅48.3 mm and ∅60.3 mm.
  • Why is it appropriate to bend the tube with a thorn?
    The advantage of thorn tube bending is that there is no flattening of the tube.
  • What shapes can you bend the tubes into?
    Tubes can be bent into all desired shapes, as long as they are within the permitted radius and distances between individual radius.
  • What is the maximum tube bending diameter on your machines?
    Our technology allows us to bend tubes up to a maximum diameter of ∅60.3 mm.
  • When bending, are different tools used for different tube diameters?
    A different tool must be used for each tube diameter and tube radius.
  • How much does each tool cost?
    The cost of an individual tool is between EUR 1,000.00 and EUR 1,500.00.
  • How long tubes can you bend?
    The usable length of the tube is 5500 mm.
  • Why can't you bend tubes longer than 5500 mm?
    Because the length of the thorn is limited to 5500 mm.
  • What kind of radius can you bend?
    The maximum bending radius is 120 mm, but it depends on the diameter of the tube.
  • Can you also bend elliptical tubes with a thorn?
    No, we can’t bend elliptical tubes with a thorn.
  • Can you also bend square tubes with a thorn?
    No, we can’t bend square tubes with a thorn.
  • Why you can't bend all tube diameters?
    As a different tool must be used for each tube diameter and tube radius, the company does not have tools for all tube diameters.
  • Can you bend the tubes into a spiral with a thorn?
    No, we can’t bend the tubes into a spiral with a thorn.
