FALCON S4020 6 kW fiber laser

FALCON S4020 6 kW fiber laser was built in 2025 in China by FFG CHINA CO., LTD. The machine was launched in March 2026 and has been in operation for a small number of hours. It is covered by a valid warranty until February 2031.

This fibre laser belongs to the FALCON S Masterline series, developed for users seeking high performance while keeping operating costs low. The machine is designed for the precise cutting of large sheets of metal with a maximum thickness of 30 mm. Cutting is performed using a fiber optic beam generated by a high-performance ULTRON 6 kW laser source. The narrow focal spot, combined with high energy density, ensures precise material machining with minimal thermal deformation. The fibre laser technology also offers greater energy efficiency and performance compared with other cutting methods.

The FALCON S4020 features a BOCHU 3D cutting head with a range of useful functions. The autofocus automatically adjusts the focal position to the thickness of the material being machined, which is essential for achieving high cutting precision. The anti-collision system reduces the risk of the cutting head colliding with the workpiece. All this is complemented by an automatic nozzle changer, which replaces, calibrates and cleans the nozzles, streamlining the machine’s preparation for operation.

To increase production efficiency and minimise downtime, the FALCON laser cutting machine is equipped with a mechanical pallet exchange system. The system enables simultaneous loading and unloading of material during machine operation, reducing the time required to prepare the next workpiece. Cutting parameters are programmed using software with a nesting function, which optimises material utilisation by appropriately arranging shapes on the sheet metal surface. This solution helps to reduce waste and improve material efficiency. The total weight of the machine is 13 tonnes.
