Tools create burr-free parts with punching machine

TRUMPF Inc. has introduced two new tools for producing sheet metal parts that come out of the punching machine burr-free. The new roller deburring tool and the deburring MultiTool eliminate the need for a separate manual deburring stage.

In the case of coated sheets and parts with forming, these tools reduce throughput times, the company says. Both tools displace any burr by chamfering the sharp edges (about 0.004 in.) on the underside of the part.

The roller deburring tool uses a specially formed embossing roll for long edges and contours with a radius of more than 0.8 in.. In connection with the MultiShear tool (a tool for punching outer and inner contours without overlap marks) the deburring tool produces quality edges while maintaining speeds of 1,600 IPM. The 3-way deburring MultiTool is suited to handle smaller radii, intricate geometries, and corners in a single stroke or in nibble mode.

Both tools are suitable for punching sheet thicknesses up to 0.10 in. in steel, stainless stee,l and aluminum. They are controlled by the TruTops Punch programming system. The tools also reduce the risk of injury when handling parts.
