Curved stainless steel sections created by CNC bending

Curved stainless steel sections created by CNC bending on our Trumpf 7036 CNC press brakes

Curved stainless steel sections created by CNC bending

CNC multi-bending curved sections

When we want to create a curved section in sheet metal we have 3 possible options.

1. Manufacture a form tool that can press the curved shape in one go. This is the quickest way to produce each part but does require what could be an expensive form tool. This is idea for high volume work.

2. If the curved section radius is larger we can always look at rolling the curve. This process is slower than a single form tool but has not set up cost. It’s idea for smaller batches of components.

3. If the volumes are not too high and the customer doesn’t mind some evidence of the production process then multi-bending is an option. This process is illustrated in this photograph. Curved stainless steel sections have been created with a series of programmed bending.

Although you can see the bend lines, and I can count approximately 30 individual bends the process is surprisingly quick, as the gap between each bend and the angle folded up is small the machine can travel quickly. Curved stainless steel sections like these can be formed up in around 1 minute.

If you would like to see our Trumpf 7036 CNC press brakes in action please take a look at our YouTube channel.

If you have a sheet metal design that needs a curved section please call our engineering team. They will be more than happy to investigate the manufacturing options open to you and the best method for your design.
