Laser-friendly clamping is an important precondition for process-optimized joining of sheet-metal components. Here the KS FlexRoller exploits its particular strengths to the full: it ensures that thin sheets are clamped without a gap and that the focal length is kept constant.
Process-optimized clamping is particularly important in the case of thin sheets. For this special application, we have developed the KS FlexRoller, which ensures that the sheets are positioned next to each other without a gap. In this way, the required quality and strength of the weld are achieved. A sophisticated pneumatic system enables the pressing force of the KS FlexRoller to be freely programmed within a range from zero to 1,000 newtons. Integration of the welding optics into the pressure element means that the focal length, which is so important for laser welding, is kept constant. In addition to the basic version, KUKA also offers many configured solutions that can be used with laser technology.

The KS FlexRoller was designed in such a way that the metal sheets are pressed together without a gap in the area to be welded. At the same time, the focal length is kept constant.
The alloy makes the KS FlexRoller particularly resistant to wear and heat. It also ensures that weld spatter sticks less than conventional materials.
The pressing force is generated by special pneumatic cylinders. The pressing motion, or compensation motion, thus has little lasting effect.
If particular sensitivity is required, a servomotor-driven pressure module generates the correspondingly low pressing force.
