CNC Punching sheet metal with Trumpf CNC punch presses
In this gallery of sheet metal component images we have illustrated below just a small selection of the bespoke sheet metal CNC punching that we produced on one day in our factories in Fareham, Hampshire. The component parts below include CNC punching the sheet metal materials stainless steel, mild steel, Zintec and aluminium alloys in thicknesses from 0.7 to 5.0mm.
“As a UK manufacturer competing in a market where most competitors units are manufactured overseas keen pricing is essential. Coupled with quality and accurate delivery promises Ray and his colleagues at V and F Sheet Metal have all bases covered. I would certainly recommend giving them a try.”
Director …UK product designers and manufacturers in South East England, 10th Jan 2012
You can see examples of sheet metal components that have had special CNC punch tooling to punch out rectangular cutouts in ventilation grilles, banana tools to produce single hit curved obround slots, blank tools for small punched disks, plunged and tapped features and a vast range of standard CNC tools including squares, rectangles, obround slots and of course circular holes. You can see that on some components more complex geometry is achieved in the sheet metal components by CNC punching shapes that are created by overlapping combinations of the standard 2D shapes. Some of the CNC punching would then have been deburred by barrel deburring or edge belt deburring. Some of the sheet metal work that is then powder coated may not have been deburred, this is a judgment that is taken with the customer to decide the best component finish needed in balance with the best component price.

| CNC punching – Electronics enclosure from 1.2mm aluminium alloy sheet metal. This component has been manufactured by CNC punching out the holes and the outer profile on one of our Trumpf punch presses. The single holes are produced by tools that are the exact size and shape required by the design. Any shapes that we do not have an exact single hit CNC tool for can be created by the use of overlapping circles, rectangles and obround tooling. | CNC punching – ventilation grilles from 0.7mm Zintec sheet metal. Sheet metal components like these can be CNC punched out in seconds with dedicated tooling. The advantage for you is a cleanly cut feature enhancing the final component finish and a reduced component price. Tooling costs are cheaper than you might think on a Trumpf CNC punch press. | CNC Punching in Fareham, Hampshire – lighting gear tray from 0.9mm Zintec. Sheet metal components such as these are well suited to CNC punching. The batch size the customer wanted was just 20 off but due to the small amount of time needed to set the CNC tools on a Trumpf punch press the component was still within the customer’s target price. |

| CNC Punching – Electronics fixing bracket from 0.9mm Zintec. Banana CNC tools have been used to produce the curved slots as single hits. Banana tooling can be used as in this example to produce single hit curved slots to provide arcs of adjustment around a central point. They can also be used when overlapped to produce disks or circular cutouts in sheet metal work. They are particularly useful where a single hit would not be possible, therefore over 76mm diameter. | CNC Punching and press work- Light fitting clamping bracket from 5mm mild steel plate. This sheet metal plate was produced much quicker than drilling the holes and cheaper than laser cutting. Again, this component shows the versatility of CNC punching on a Trumpf punch press, 5mm thick mild steel plate was punched out with standard CNC tooling. The component to the right was punched on the same machine on the same day. | CNC Punching – electronics heat sink plates from 0.9mm aluminium alloy. These small parts were simply produced by punching the 2 holes first and then punching with a single hit down a die the correct size for the outer circumference. The final part was collected in a tin below the punch press, the total time to CNC punch each part was under 1.5 seconds. |

| CNC punching – Heater assembly end plate from 1.2mm stainless steel alloy. This stainless steel component has an eliptical profile which has been produced by CNC nibbling with a 12mm square tool. The Radan software takes care of the tool positions we only have to drawn the elipse and allocate a CNC tool, easy when you know how. | CNC punching – Light fitting back plate from 1.5mm aluminium alloy sheet metal. The Trumpf 200 and 3000 punch presses are equally at home CNC punching mild steel, stainless steel or aluminium alloys. Other than separating the waste material for recycling the programming and tooling is the same for all 3 material types. Ideal part for CNC punching in our factories in Fareham, Hampshire, UK. | CNC punching – Electronics chassis from 0.9mm mild steel. Again, a typcial CNC punched part, the tabs in the middle of this component are bent out on a CNC press brake but they may sometimes be folded out by hand if a line of holes have be CNC punched in place. This technique of folding alone the dotted line is quite popular when trying to save money by reducing manufacturing time. |

| CNC Punching – Electronics sheet metal earth tag from Zintec. In the past, small sheet metal parts like these would have been produced by cutting on a guillotine, corner notching and using a fly press to pierce a single hole but not today. The whole component is CNC punched out from a sheet of Zintec in under 3 seconds and with consistancy of size throughout the batch and from batch to batch. | CNC Punching – Electronics connector blanking plate from mild steel. Again the flexibility of a CNC punch press is shown in this small component, radiused ends with plunged and tapped M3 threads all produced on the Trumpf 3000 CNC punch press. The thread is formed rather than cut so there is no swarf to remove from the part before being processed further or shipped to the customer. | CNC Punching – Speaker cabinet back panel sheet metal work from 1.2mm mild steel. This sheet metal fabrication was manufactured as part of a set of parts on one sheet of mild steel. The Radan software enables us to experiment with mixing different parts together across several sheets to produce the best material utilization when maufacturing, keeping the costs to a minimum. |

| CNC Punching – Light fitting body sheet metal work from 0.9mm Zintec. Sheet metal parts like these are typical of the work that we manufacture everyday of the week here in Fareham, Hampshire. Having 2 multitool stations each with 10 tools in and another 16 separate tool stations there is never s shortage of tooling options on our Trumpf 3000 punch press. | CNC Punching – Flood Light cowl fixing bracket from 0.9mm stainless steel alloy. Simple sheet metal work component produced in small numbers often from offcuts of material from other larger parts. The Trumpf punch presses are very adaptable in being able to run large standard sheets and special cut blanks down to small offcuts that might otherwise be scrapped. | CNC punching – Speaker cabinet front frame sheet metal work from 1.2mm mild steel. Larger components like this mild steel frame with windows in them can sometimes be used to produce other parts that maybe part of the set from the scrap sheet metal inside the window. When we can do this we will use this technique to help save you money on material. |
