Compact 3D scan head for precise and highly dynamic laser material processing

The Fiber Tiger is an extremely compact and robust scan head for robot‑assisted laser processing and other ‘onthefly’ type applications in the mid to high kW range.

The scan head features a highly dynamic Zaxis for ultrafast and precise 3D laser material processing. It has been designed especially for welding and cutting applications and can be employed in a wide variety of industrial sectors, for example automotive, aerospace and machine construction. The Fiber Tiger is suitable for industrial-scale processing of all commonly used materials, such as metals, plastics and ceramics.

The scan head can be operated with all commercially available singlemode or multi-mode fiber lasers.

Crossjet for Fiber Tiger

The innovative ARGES Crossjet design ensures the long service life of the protective window and optics, even in harsh ambient conditions with intense sparking, while consuming only a very small quantity of compressed air. 

The Supersonic Crossjet combines a de Laval nozzle and the practical application of the “air amplifier” principle: The compressed air is first accelerated to a supersonic speed by the annular-shaped de Laval nozzle. The nozzle is arranged in such a way as to create a vacuum at the rear of the Crossjet that causes the ambient air to be drawn in and also accelerated. 

This produces an amplified air stream several times greater than the flow rate employed even with a lower consumption of compressed air.

  • For the industry-standard operating pressure of 6 bar (600 kPa)
  • Homogeneous air stream as a result of the air supply from both sides
  • Efficient design for a strong air stream with low consumption of compressed air
  • High flow velocity over long distances for optimum particle deflection
  • Long service life for the protective window and optics
