Product Details
Mechanical characteristics
The CNC bending machine can bend complex three – dimensional pipes left and right.
■ The 5-13 axis servo motor controls accurately.
■ The left-turn and right-turn functions of 1-4 layer molds can be realized.
■ Large radius or spiral products can be bent, with push bending function.
■ The computer system for forestry industry has the function of 3D interference inspection.
■ The machine can be connected to a robot and a three-dimensional measuring instrument.
■ The input pipe fittings data can be directly used to generate 3D stereo images, and can simulate the forming process of the pipes, previewing the pipes forming graphics.
■ It has a complete alarm function for machine failure and displays alarm information on the screen, which is convenient for operators to find and troubleshoot.

Frequently Asked Questions
Our CNC pipe benders, tube cutting machines and tube end forming machines process carbon steel, stainless steel, aluminum and copper. They handle round, square and rectangular tubes for furniture, auto parts and engineering machinery industries.
We offer customized machines based on tube specifications, bending angles, forming processes and automation levels. Multi-station composite functions are available to fit your exclusive production workflow.
All CNC models adopt intelligent control systems with easy program storage. Stable repeat machining accuracy reduces reject rates, ideal for mass continuous production.
We design fully automatic pipe processing lines integrating cutting, end forming and bending. Seamless process connection cuts labor costs and improves overall production capacity.
CNC pipe benders enable one-step multi-angle forming and small-radius bending. They avoid tube wrinkling and collapse, suitable for complex special-shaped pipe workpieces.
Tube cutting machines deliver flat, burr-free cutting surfaces. Tube end formers support flaring, shrinking, bulging and other end processes, enabling multiple pipe end forming operations on a single machine。
