Simple CNC punching Techniques
Today I thought it would be useful to run over a couple of common CNC punching techniques that are often used here at V and F Sheet Metal. Knowing that none of us want to spend money where we don’t need to we always try our best to use existing tooling to produce new parts.
CNC punched diamond patterns
This ventilation pattern was created by turning a 4.5mm square tool at 45 degrees and repeating a simple column and row pattern. By using a range of different sized tools and pitches a wide range of open area performances can be achieved. This is particularly useful if the order volumes don’t justify bespoke cluster tooling or if you are still prototyping and need to try out different air flows for you design.

CNC punched dimples
A standoff foot is often needed to enable a sheet metal base tray to be lifted off the floor or wall. We have a range of dimple tools that enable us to achieve this for you. If a fixing hole or even keyhole slot are needed again this is easy to produce and we have many tooling options available for you.
CNC punched vents
When it comes to ventilation areas in sheet metal we have a vast range of options. For some it’s simple a CNC punched window which a fan can be screwed to with a separate grill. Others might want a series of ventilation louvres formed into the sheet, which can be achieved with CNC punch press tooling.
A popular alternative is to have an area punched with holes of slots to allow the correct amount of air flow. This can be with special cluster tooling if the volumes are high enough to justify the tooling costs. If the volumes are lower then using one of our many standard CNC punch tools is the cheapest and easiest solution. This pattern of vent slots was produced with one of our standard obround tools. For more information on standard punch press tooling take a look at our tooling pages.
