CNC punching stainless steel sheet metal panels in Hampshire
CNC punching stainless steel panels
A Trumpf 3000 is the perfect machine for CNC punching small to large batches of sheet metal panels. CNC punching at its simplest is a machine that can move a sheet of metal in a x and y direction and stop at a defined position and pierce a hole. The hole is pierced with a punch that is punched through the sheet and into a die to produce a slug of metal that falls into a waste bin below. There are various methods of achieving this with different tooling systems depending on the manufacturer of the CNC punch press but they all achieve the same result, a hole in a sheet of metal. As well as single holes tooling can be used to combine several holes together to produce more complex geometries and even forms in the sheet such as ventilation louvres, spacing dimples and plunged screw thread positions can be achieved with the correct tooling.
The component shown here is a large stainless steel panel being CNC punched out with a protective plastic coat left in place ready to protect the stainless surface in production whilst being bent up.
CNC punching mild steel sheet metal panels in Hampshire
CNC punched mild steel panels
In contrast to the large stainless steel panels above here we have CNC punched much smaller mild steel panels. When hundreds of small panels are wanted together they can be nested with common lines to save material and speed up the CNC punching cycle with less punching. These panels have been held within the sheet by a 0.1mm corner tag which is enough to stop them falling out but not too much so that they can be broken out leaving very little witness which can easily be deburred off after punching.
If you have a sheet metal panel and think it could be produced by CNC punching please just let us know and we will be happy to investigate for you, sort out different price breaks and even send you an image of what tooling we would use and how this would look on the final panel.
