CNC punch press tooling
The latest component I’ve been asked to make has given me the opportunity to talk about CNC punch press tooling, and more specifically the banana tool. Although the part is simply circular in shape, it still needs some thought on how this shape is created. We could have used the Trumpf fibre laser but in this case we chose to run the job on the Trumpf 3000. If this machine had been busy then we could have swapped to the Trumpf 200. Obviously, we like to offer this flexibility in our work shop and our regular customers appreciate this, as they know their job will not be held up in a queue.
Radan view of component
The first photo is a Radan view of the part. Below the circular part is the CNC punch press tool used to produce it, a banana tool. This tool has a choice of external and internal radii. These could be same or different to each other. In this case the internal radius of the tool was used to produce the external circumference of the component. We have many tools available at V and F Sheet Metal so if one doesn’t suit, we’ll probably find one that will! The tool could be used to create the external radius of the part or the internal radius of a hole in a piece of metal.
Radan nest of parts
The second image shows the Radan nest of parts arranged on a 2m x 1m sheet of 3mm thick aluminium.
Obviously as components are cut out of the sheet they will fall out so there is a chute underneath the machine for collection. All holes in the component are punched out first and the cutting out of each individual component is the last step. The left over “skeleton” sheet and punched slugs are recycled. For the final stage of production the components are sent off for powder coating.
