Sheet metal plates produced on a CNC punch press
Sheet metal plates
CNC punched plates
These sheet metal plates have been CNC punched from Zintec coated mild steel, they are typical of the complex sheet metal plates that can be manufactured on Trumpf CNC punch presses. We have used a combination of rectangles, circle and corner radius tooling to produce the inner shapes and outer profile on these plates. You can see that the parts have been nested together to reduce the amount of material usage and increase the component yield from each sheet. Each plate is held in position on one corner of each arm by a 0.1mm piece of metal, which is defined in the CNC program. The part can easily be broken out of the nest and the small tag de-burred off along with the outer profile.
Sheet metal fixing plates
These simple sheet metal plates have been manufactured in our sheet metal facility in Fareham, Hampshire with the use of our Trumpf CNC punching machines. We have CNC punched out the basic outer profile and inner holes using a range on rectangular and circular CNC tooling. The parts at the production stage shown in this photograph are waiting to have an M10 threaded zinc plated steel bush inserted into the large hole in the middle of the plate. The bush will be inserted on one of our 4 hydraulic powered fly presses finishing the component off and making it ready to be sent to our customer. These simple little fixing plates are used as anchor points in wooden speaker cabinets to help reinforce the flying points and wall mounting points.

Here’s a good view of a sheet metal plate blank that has been CNC punched in a full sheet of Zintec coated mild steel. You can see that the components have been nested front to front and back to back. This technique allows us to adopt “common line” cutting where a slit tool produce the left hand side of one part and the right hand side of it’s neighbour with the same punching operation. Common line cutting helps to reduce material usage and tooling hits, helping to reduce component costs.
