Trumpf 3000 CNC punching pre-coat sheet
CNC punching pre-coat sheet metal
The great thing about using a CNC punch press is it’s ability to process such a great range of material types and finishes. As well as plain mild steel, stainless steels, aluminium alloys, copper, brass etc we can work with pre-painted materials, plastic coated steels, pre-anodised aluminium sheet with peelable protective films to name but a few. Here we have a Trumpf 3000R CNC punch press punching mild steel sheet metal that has a zinc coat on the reverse face and a plastic coat bonded to it’s front face with a peelable plastic protective film on top. The punch press is using a range of cluster tools, some with up to 25 pins, to produce a ventilation area in just seconds.

Here’s a much better view of the cluster punched ventilation grilles shown above on the CNC punch press bed. By using the Trumpfs’ unique presser foot, where the whole punch head presses against the top of the sheet metal at the point of piercing, we are able to maintain a good level of flatness even when punching many thousands of holes in these components.

The Trumpf 200 may be our older CNC punch press but it’s still a great production machine punching out sheet metal profiles in a range of materials and thicknesses. It’s able to handle sheet from 0.4mm to 6mm thick and sizes from small pre-cut blanks right up to 2500mm x 1250mm sheet. In common with all Trumpf CNC punching machines the head can rotate 360 degrees allowing all tools to rotate producing more efficient punch nests and speeding up CNC programming time. We can also cope with punching some aluminium extrusions by using mounting jigs in the Trumpf’s clamps making this machine a very versatile production addition to our CNC punching team.

These aluminum chassis plates are just perfect for producing on a Trumpf 200 CNC punch press. With multi-tools and a range of standard tools that we have built up over many years of production a component like this needed no new special tools which was a bonus for the customer.
You may have a sheet metal job and not sure whether it should be CNC punched or laser cut, let us have a look and we can offer you the best route to a quality part at the right price.
