Trumpf has introduced the TruLaser 7040, a machine that enables two cutting heads powered by a 6kW laser with beam splitting to process two parts simultaneously. Particularly suited to thin sheet processing, it is also ideal for lights out operation and for applications that require high contour precision. Typical examples are the production of seals, saw blades and metal furniture.
The machine is equipped with the TruDisk 6001 laser that offers highly cost efficient ratio of energy consumption per metre cut. When it is not cutting the laser automatically switches to standby mode, in which it uses virtually no power.
The laser delivers 3kW of laser power per head, but that doesn’t mean cutting speed is halved. It is reduced only slightly with thin sheet and virtually not at all with mild steel. As 3kW is sufficient for the process, the cost share of the laser, per metre cut, falls by 50 per cent with the dual heads. As an alternative the full 6kW can also be concentrated on a single head enabling sheets up to 25mm thick to be processed. = In either case the beam is guided by fibre optic cable from the resonator to the cutting head.
Another feature is the use of carbon fibre components. The materials used are proven in the racing car and aerospace industries and have allowed Trumpf to develop a cross beam that is both lightweight and rigid. This improves the machine's dynamics, increasing acceleration up to 25m/s2 and a maximum simultaneous axis speed of 304m/min.
