There are a growing number of engineers deciding that CNC tube bending is a better option for their production systems versus fitting together or fusing stainless steel tubes or other metals. That’s why we updated our most-popular resource: 

Time and Cost Savings with Precision Tube Bending

The free download is now packed with even more tube bending solutions for project managers. Updates include:

  • The most frequently asked questions about CNC tube bending
  • A CNC tube bending radius chart for the most-requested bends
  • The four attributes of CNC tube bending that will make your production systems last longer

You’re probably well aware that production systems for transporting gases, liquids and chemical compounds must be free of leaks, wrinkles, fissures and a variety of other faults. Any one of those faults may cause flow restrictions that can trap elements moving through your system. When flow restrictions occur, you’re looking at a slow down of production, potentially costly repairs on that section of your delivery system – or even a crash of your entire system.

Machined tube bending using a computer numeric controlled (CNC) tube bender is the ideal solution when accuracy and repeatability are critical – and when time and money are a factor (and when aren’t they a factor?).

​Precision tube bending company, Axenics’ technicians have touted the benefits of CNC tube bending for years, and many of our longtime customers have switched from manual tube bending, fittings and weldments to seamless, repeatable CNC tube bending for their production systems.

Benefits of CNC tube bending include:

  • Power
  • Speed
  • Accuracy

We program our in-house CNC tube bender to perform some of the tightest tolerances available, as multiple industries require intricate tubing systems to accommodate growing production on a shop floor that stays the same size.

We retire worn tooling and maintain smooth clamps on the CNC bender to ensure your steel tubes arrive:

  • Identical
  • Wrinkle free
  • With a handsome cosmetic finish

We included a radius chart in our tube bending resource as we receive a lot of questions related to our radius capabilities, such as:

If the OD of the tube we plan to use is not a standard size, what are your flexibilities with the design?

Our experts will look at your design requirements to see if there’s a solution to bend a standard size tube into a shape or angles that will fit into your space requirements, with minimal fittings to ensure consistent performance without degradation.

The four attributes of tube bending that will make your systems last longer include the machine, material, tooling and lubrication used for the job. Our updated resource goes in-depth on these attributes, such as the benefits of using a mandrel in CNC tube bending. With mandrel bending, a steel rod inserts into the tube while it is bent to give the tube additional support to reduce wrinkling and damaging the tube during the bending process.

Mandrel tube bending elicits highly accurate, repeatable results for jobs with tight or large radius bends. The firmness of a mandrel is very important, depending on the firmness of the tube. For extremely durable tubing, a soft mandrel is used, and a hard mandrel is used on softer tubing. This prevents the mandrel from sticking to the inside of the tube, which can damage the tube.

One other thing to remember about CNC tube bending is the bending happens “cold,” meaning the temperature of the raw stainless steel or other metal tubing does not change during the bending process. Therefore, the chemical makeup of the metal does not change, maintaining the durability of the metal tube.
