MITSUBISHI ML 3015 eX-F40 4 kW fibre laser

MITSUBISHI ML 3015 eX-F40 4 kW fibre laser built in 2016 in Japan is used in precision machining of various types of sheet metal. The extremely technically advanced machine uses the most advanced technology available on the market, including an energy-efficient and trouble-free laser source with the highest energy output, which feeds the cutting head with a 4 kW fibre optic beam. The magnetically mounted Zoom Head type head additionally optimises cutting parameters automatically according to material thickness and reduces the effects of collisions.

The structure, based on a high-quality casting, is designed for maximum user comfort. The large working area is covered by an all-glass, automatically rising door, while the resonator and all electrical systems are integrated into the machine frame. In addition, in the case of failure in one of the diode modules, a power reserve allows the machine to continue operating at nominal performance.

The MITSUBISHI fibre laser is offered with the necessary systems and equipment to fully automate the machining process. This includes a 1000 KG pillar jib crane with sheet metal vacuum lifter and CAD/CAM software with NESTING function, which arranges 2D parts in such a way as to best save space on a machined workpiece. The MITSUBISHI ML3015 eX-F 40 fibre laser cutting machine weighs 8900 kg.
