Laser Processing Compact 3D laser machine cuts filigree single components

Redakteur: Kathrin Schäfer

At a recent in-house trade show, Trumpf presented its new TruLaser Cell 3000 5-axis laser-processing system, a compact 3D machine designed for the fine cutting of filigree single medical device components and rapid processing of larger series in 2D or 3D.

The machine operates with the user’s choice of Trumpf TruFiber, TruDisk, TruDiode or TruPulse fixed-body lasers offering power to 8 kW. It can cut and perform other processing tasks efficiently and with high precision thanks to sophisticated controls. The system’s capacity for variable beam formation means that the focal point and focus diameter can be adjusted just as easily as autofocus and aperture on a digital camera. Thus, the point of focus automatically adjusts to the thickness of the sheet metal to be processed, and the beam diameter can be expanded to four times the fibre diameter of the light-conducting cable. This affords advantages for welding particularly, and considerably reduces the periods of nonproductive operation. With only a single focal distance of 150 mm on the optic, a switch from a spot of 100 µm for cutting to a spot of 400 mm for welding can be performed without manual retrofitting.

The laser beam automatically adjusts to material type and thickness on the basis of technology tables. Using the integrated ControlLine distance-sensor technology, the system’s focusing optic operates at the correct working height even on uneven sheets. Two beam sources for different applications can be attached via one beam switch. Control of the various lasers is performed at the touch of a button; it is not necessary to change the beam-delivery cable for this. Additional flexibility is ensured by the modular workpiece chamber, which can be adjusted to suit different components with little effort.

Processing on the TruLaser Cell 3000 does not require moving the workpiece: instead, the optic “flies” around the workpiece. For 3D processing, the pivoting axis achieves an entering angle up to 135°. The axes are moved via linear direct drives. And, instead of a ball spindle drive, a magnetic field adjusts the axes without contact and with little wear. This trick results in the 3D processing space to be twice the size of that in the predecessor model, and it makes automation easier.
