CNC Punching Sheet Metal Brackets
Trumpf 200 chute
One of the many useful features of using a Trumpf 200 CNC punch press is the component chute that is built into the bed of the machine. On the Trumpf 200 it can cope with small blanks up to 180mm square. By controlling the order that the CNC punch press tools are used the sheet can be positioned over the chute opening so that the last punch operation can free the blanks from the parent sheet and allow it to fall away from the sheet and straight down the open chute and into a collecting bin below the machine.

The sheet metal brackets are created with a series of standard CNC punch tools working in combination to produce the final component shape. These tools we hold on the shelf and can use them any customers standard work that comes along. If special tools are required we can offer advice and price options direct from the original machine manufacturer to get the best tool options to save money and length of tooling life. At this stage you can see that all the internal holes and slots have been CNC punched and the outside profile has been created with the use of several different tools.

The final hit for each sheet metal blank sends it down the chute and into the bin leaving the hole behind in the sheet. This view shows quite nicely the arrangement of tooling used in the CNC punch marks that are left behind. The advantage of this method of CNC punching is that there are no tags left holding the part in the punched sheet so the de-burring is easier. It is also quicker to collect the parts than having to break or shake them all out of the sheet. This all saves time and as we all know time is money.
