Forming: Punching in the Third Dimension

Your punching machine can do more than just punch. Fitted with an intelligent punching head and the right tool, your machine will also demonstrate its talent for forming. This allows you to fully process a great diversity of sophisticated components on one machine—and even burr-free if required. It is also efficient for small quantities as tool costs are low and setup times are short. 

The ability to produce burr-free sheet-metal parts directly on punching or punch laser machines saves you the time-consuming process of retrospectively removing the punching burr. This considerably reduces the throughput time, in particular for coated sheet metal and formed parts. Furthermore, the improved edge quality lowers the risk of injury when further processing the parts. 

Roller Deburring Tool

The roller deburring tool is mainly used for simple, large-surface contours. The punched edges are thus perfectly rounded off, which is a decisive advantage for visible edges in particular. A high-quality result is obtained with all of the sheet thickness ranges by adapting the roller contour to the modified burr and to the width of the separation gap.

Ball Deburring Tool

You can get an even better edge quality if you use the MultiShear slitting tool in addition. For shapes with contour radii of less than 20 mm, the deburring MultiTool is to be used. The ball deburring tool is suitable for smaller contours, holes and workpiece corners. Specially hardened balls press the punching burr into the base metal. In doing so, a chamfer is produced on the upper side of the part.  Thanks to the tapered punch head, deburring near formed areas is also possible.

Deburring MultiTool

TRUMPF’s deburring MultiTool, with its three embossing inserts in the die, excels on radii of less than 0.8 in in particular. The tool presses burrs flat in a single stroke or in nibbling mode, even in corners and small contours.

The MultiTool makes your machine more productive by integrating up to 10 different punches and dies into one tool. The strengths of the MultiTool are particularly notable in processing sheet metal parts with small punches of different sizes.

Benefits

  • Shorter production times through complete processing on one machine
  • Lower risk of injury
  • Deburring of all geometries, whether simple, complex, small or large.
  • Also for coated sheets and for parts with formed areas
