CNC punching circular discs with radius banana tooling

Tuesday, June 11th, 2019

CNC punching circular discs with radius banana tooling is a practical alternative to laser cutting.

If you want to produce a perfect even smooth circle laser cutting is king. If however you want to produce a good circle in sheet metal and your component has features other than holes then perhaps CNC punching is a solution. You may have a circular chassis with tapped threads or ventilation louvres. Perhaps a circular disc with formed dimples is needed and again CNC punching with banana tooling is a perfect method of production.

There is another useful tip we have found and that’s although we would buy a banana tool with a given cutting radius it can be used for a range of circle sizes. Both circles smaller and larger can be cut with acceptable edge finish. If for instance you have a circular gear tray that needs to fit into a plastic moulding, it may be that the gear tray is not seen buy the final user of the product. You can then allow for an edge that is not perfect but still functional. This enables us to produce a wide range of CNC punched circles with a small range of tools. If also means that we can often quote for new work without the need for new tooling costs.

To see a range of our Trumpf CNC punch press banana tooling take a look at this link.

When CNC punching circular discs we can tag them in if needed. They can then simple be broken out at the end of the manufacturing cycle. We can however completely free the component from the sheet and allow it to fall through a chute in the machine. You can see this in action if you view the video show here.

Not sure if this is for you? Call us and we will be able to chat through your project. We can easily take your drawing and run it through our CNC programming software. We can then offer you the best solution and show you the edge profile you would receive.
