CNC punching circles couldn't be easier with banana tools
We all know that CNC punch presses are very good at CNC punching holes very quickly in any sheet metal material. If you are looking for sheet metal components with circular holes or square and rectangular cut-outs created by CNC punching several overlapping tools then you can't do better. And, again if you have a component that has straight sides to its outer profile you can't go wrong with CNC punching. I often have customers say to me that they have to have a sheet metal component laser cut because it has a larger circular hole in it or it has a curved outer profile which is simple not true. Here at V and F Sheet Metal can produce sheet metal components with large circular holes and part curves with very few hits using CNC banana tools. The banana tools can be made to the exact radius needed or often we have similar sized banana tools from previous projects that can approximate the radius needed. By indexing the CNC banana tool as it is punching in our Trumpf CNC punch presses we can create a continual smooth curve. It's always worth asking when you are designing a new component with internal or external curves to see whether we can CNC punch it for you.
