Roll Dies by OD size range	CLR minimum is defined by the OD "D" and the materials selected for the product's ability to be worked. One or more of our CNC Benders are rolling tubes each day,  this is a common process for our team It is possible to combine traditional bends with rolls in the same complex part geometry.

How Does It Work?

CNC tube bending leverages cutting edge computer technology and high strength machinery to create custom tailored bending patterns.

The process is made possible by the combination of the CNC controlled bending head, CNC feeding mechanism, and the headstock, which are managed by a computer program called CNC code. Our engineers develop a 3D CAD model of the specified project and export the design into the CNC code. The machine then uses that code to dynamically reposition the head and feed the tubing through the desired process at shifting speeds, bending the raw material with variable radii and variable axis along the tube’s length.

Want to explore the potential of a CNC tube bending design for your product? Ready to move forward with your large batch? Our sales and engineering team is ready to walk you through the process of CNC tube bending, so your next manufacturing run is seamless, accurate, and cost effective.
