Two freeform tube bender companies and models in Asia

  • by

The freeform tube bender is a machine designed to bend metal tubes into complex and intricate shapes with high precision. Unlike traditional tube benders, which are limited to simple bends along one or two planes, freeform tube benders operate on multiple axes, allowing for bending in three-dimensional space. This capability enables the creation of highly customized and irregular tube geometries, including twists, spirals, and compound bends. Freeform tube benders are essential in industries such as aerospace, automotive, and manufacturing, where intricate tube designs are required for components like exhaust systems, roll cages, and structural frameworks. These machines typically incorporate advanced technologies such as CNC controls, servo-driven bending, and multi-axis motion systems to achieve accurate and repeatable results.

  • The 3-axis freeform tube bender from Japan’s Nissin(日進精機) allows for flexible bending without the need for corresponding molds for bend radii. It can also process shapes with continuously changing bend radii, similar to mosquito coils. Additionally, due to support provided by the tubing during processing, there is minimal deformation of the cross-section, resulting in beautifully crafted finishes.
  • The BIT 3-axis freeform tube bender provides moderate flexibility for simple to moderately complex tube bends. The 6-axis version offers increased versatility with rotational axes, allowing for highly complex tube geometries. Both models feature advanced CNC controls and servo-driven bending, catering to various industries’ needs.

The difference between a 3-axis freeform tube bender and a 6-axis freeform tube bender lies in their degrees of freedom and capabilities.

  • 3-axis freeform tube bender: Operates on three axes: X, Y, and Z. Can bend tubes in 3D space to create simple bends, curves, and shapes. Offers basic flexibility for bending operations but may be limited in its ability to create complex geometries. Suitable for applications requiring relatively straightforward tube bending, such as automotive exhaust systems or HVAC ductwork.
  • 6-axis freeform tube bender: Operates on six axes: X, Y, Z, A, B, and C. In addition to the three linear axes (X, Y, Z), it also includes rotational axes (A, B, C). Provides significantly more flexibility and capability for creating complex bends and shapes. Enables bending operations that involve twisting, spiraling, and multiple compound bends in various directions. Ideal for applications requiring intricate and precise tube geometries, such as aerospace components, roll cages for motorsports, or architectural structures.

In summary, while both 3-axis and 6-axis freeform tube benders are used for bending tubes, the 6-axis bender offers much greater flexibility and versatility, allowing for the creation of more intricate and complex tube geometries. However, it typically comes with a higher cost and may require more advanced programming and setup.
