The modular concept opens possibilities Swisstec has anticipated this trend and develops and produces very compact and at the same time modular systems. As a result customers gain high flexibility regarding applications and implementation. The integration of different beam sources such as fibre, femto- and picosecond lasers enable various processing tasks including cutting, drilling, welding or marking. Combining those tasks on a single system is possible by applying appropriate axes, optics and laser heads.


Integrating mechanical processes This concept does not only show potential due to the combination of different laser sources. Also the additional integration of mechanical processing steps like grinding and forming is demanded frequently. The implementation of this modular approach can best be demonstrated with the help of a specific application requested by a customer. A medical instrument needs to be manufactured out of steel tubes with outside diameters varying between 0.27 mm and 0.8 mm (figure 1). Required processing steps are laser cutting, laser welding, grinding and forming of the metal tubes. Besides the two standard axes (X: lateral and A: rotation) this system integrates two axes to position the laser spot in Y and Z direction to work outside the middle of the tube and to compensate the tube’s radius.
