Punching machine virtually eliminates scratches

The latest generation of TRUMPF’s TruPunch 5000 provides greater flexibility due to the machine’s increased speed and the new active die option, which virtually eliminates scratches during processing.
With the active die, each time the sheet is positioned, the die is lowered slightly so that it does not contact the sheet. The moveable die also expands the forming possibilities of the machine since the total distance between the table and punch can be used. In addition, the active forming stroke from below the sheet increases the machine’s flexibility because larger tools may now be used; even marking from underneath is now possible. In addition, the new generation of the TruPunch 5000 operates about 10% faster than its predecessor, with 1,400 strokes per minute for medium format and 1,200 strokes per minute for large format. This means 200 more strokes without using more energy. The TruPunch 5000 can process a maximum sheet thickness of 0.3 in.
