Economical High Precision Bending

Simple to operate, accurate, and reliable are the characteristics that define the TruBend Series 3000 press brake from TRUMPF Inc. (Farmington, CT). The machine’s closed-frame design provides high overall rigidity for higher precision than the previous generation. The backgauges can move across the entire length of the machine bed, enabling unrestricted use when bending at the ends of the machine. Automatic CNC crowning makes for constant angles. As the fastest press brake in its class, the TruBend 3100 also features a press force of 110 tons and 118 in of bending length in a space-saving design. The machine comes standard with a two-axis backgauge, with the option to expand to a four- or five-axis backgauge, making it possible to bend parts accurately, even when complex part geometries are involved.

The simple and intuitive operation of this press brake is ideal for entry into precision bending. The operator can draw and program parts graphically with modern multi-touch control. The exact bending parameters are calculated automatically based on data derived from decades of experience in precision bending. 3D visualization further simplifies the work and checks the program for potential collisions. Preexisting programs are easily imported either via a USB interface or a network connection. Upgrading bending capabilities to the TruBend Series 3000 is simple since even third-party tools can be used without an adapter. Simply select from a number of different tool clamping concepts. Manual clamping comes standard, with the upper and lower tools secured with Allen screws. The quick clamp option facilitates rapid clamping of the upper tools with a lever, reducing set-up times. The fastest option for set-up is automatic hydraulic clamping. Each option automatically centers the tools, which are inserted vertically.

A variety of components ensures that this press brake is safe and ergonomic. BendGuard uses a laser light field to monitor the area beneath the upper tool. If there is a break in the barrier – a hand interrupting the light field, for example – the machine will stop, protecting the operator from injury. This technology enables the operator to confidently run the machine at full speed for maximum productivity. The BendGuard is positioned at the sides of the machine, next to the ends of the ram. In preparation for inserting tools from the side, the BendGuard can simply be moved so that it does not interfere. The position of the BendGuard is also easily and incrementally adjusted to accommodate upper tools of differing heights. The machine’s compact design features a small footprint, the interior space for the machinery is readily accessible, and it is quickly installed because it is delivered completely assembled. The foot switch used to start the bending stroke is also easily repositioned. LED lights in front of and inside the machine also keep the workpiece well lit.
