VR3 customers have always been impressed by the accuracy, fit and efficiency of our CNC notched tube welding kits. Adding CNC tube bending to our services gives designers and engineers even greater latitude and flexibility for tube frame prototyping and production.
Combining CNC notching with CNC bending provides even greater value and productivity for welded tube structures.
VR3 has developed a process to “straighten” complex bent tube geometry and preserve the orientation of the end notches.
These “pre-notched” tubes are cut with our proprietary CNC notching process prior to bending, reducing efforts to fit and grind at weld assembly.
More specifically, the straight, notched tubes are loaded into our CNC tube bending machines – with the same 3D CAD data and orientation so the bends bring the cut ends around to their precise points of intersection to fit with the other tubes.
We use either semi-auto rotary draw or CNC mandrel tube bending, depending on the bend geometry, quantity, scheduling and cost.
Replace traditional manual skilled labour intensive process with our CNC controlled technology.
Whether they’re out in plain sight or hidden within a structure, the seamless strength and beauty of ready-to-weld tubes, creates new possibilities, especially for performance racing and custom projects.
For further technical details, consult our bending guidelines for Manual Bending and CNC Bending.
You can also see our CNC Bend Tooling list for an inventory of our current tooling.
There are many variables, constraints and combinations of features that affect the feasibility of tube bending. Each formed tube must be reviewed by VR3 Engineering anyway, so include us in your design process early – it will help us help you, and could save you a lot of time and expense.
