Aluminium sheet metal sections after CNC bending
CNC bending aluminium sections in CNC press brakes
Sheet metal aluminium sections such as these shown here are often manufactured here at V and F Sheet Metal using CNC punching and CNC bending techniques. A component like this can be programmed for CNC bending in 5-10 minutes on our Trumpf 7036 CNC press brakes. When we are bending sheet metal work like this even though we can create the whole program off line if we want to or at the shop floor controller on the press brake we still have to manufacture 1 and test it first. The material gauge can change from batch to batch within its tolerance, the hardness of the material and the grain direction all go to create a variance in the bending even with the same bending CNC program. We cope with this by using program corrections, we bend 1 component and inspect the result to drawing and then make corrections to the CNC program. We only have to tell the CNC press brake how far it’s out and the software automatically adjusts the bend angles and then normally that’s it we are ready to bend all the parts the same size as the drawing.
If you have a sheet metal work projects which needs CNC bending and you are not sure what can be achieved please give us a call on 01489 577786 or check out our bending tooling tables for more information.
