Trumpf TruLaser Cell 7040

The Trumpf TruLaser Cell 7040 is a 5-axis TruFiber laser cell with 4,000 mm (157 in) of X travel and a laser of 3,000 to 6,000 W, listed for four processes: 2D cutting, 3D cutting, laser welding and laser metal deposition. Y travel is 1,500 or 2,000 mm (59 or 79 in) and Z travel is 750 or 1,000 mm (29.5 or 39.4 in), depending on the version.

The process list is the reason to look at this cell. A shop with mixed work can run cutting jobs and welding jobs through one machine in turn, where a cell that only cuts would wait between cutting jobs. The table does not say what optics or equipment each process needs, so ask what a change from cutting to welding or to deposition involves, how long it takes and which parts of it are in the base machine.

Two values are given for Y and two for Z without a note on how they pair up. Confirm with Trumpf which combinations of the 1,500 or 2,000 mm Y and the 750 or 1,000 mm Z are built. No maximum workpiece size is listed either. On the smaller TruLaser Cell 8030 the workpiece limit is well inside the travel, 2,540 mm of part length on 3,000 mm of X, so do not assume that a part as long as the travel will fit here.

Each linear axis moves at up to 100 m/min, and 173 m/min with the axes combined. Acceleration is 9 m/s² in X and 10 m/s² in Y and Z. B swivels ±135° and C rotates continuously, both at 90 1/min, with 200 rad/s² on B and 100 rad/s² on C. For fine contours Trumpf lists dynamic cutting optics with ±9 mm of travel at 40 m/s², a fast stroke at the head that spares the large axes from reversing on every small feature. Positioning accuracy is 0.08 mm on the linear axes and 0.015° on the rotary axes.
