At its Intech in-house exhibition from May 17 to 20, 2022, Trumpf will showcase a new laser cutting machine that is particularly suitable for oversize sheet metal.
The TruLaser 3080 fiber effortlessly cuts components out of eight-meter-long metal sheets. The machine is particularly suitable for heavy and large components weighing up to 7,850 kilograms, such as facades or trailers for trucks or cranes. But the TruLaser 3080 fiber also processes small and medium-sized workpieces with ease. Therefore, users can easily utilize them to capacity and significantly increase their manufacturing capacity.
“In the sheet metal processing market, there are only a few companies that can precisely cut oversized components. As a solution provider, this machine gives our customers a competitive edge and the ability to process even more jobs in less time,” says Trumpf Product Manager Patrick Schüle. The line is suitable for various materials from aluminum to mild steel and sheet thicknesses up to 50 mm.

Multi-shift operation without automation
The TruLaser 3080 fiber can also be used in multi-shift operation without additional automation. It has an automatic pallet changer that automatically inserts a second sheet after the first cutting pass. This creates a total processing area of 40 m² of sheet metal. The machine can thus cut components for several hours without an employee having to add raw material.
Less material, more productivity
Due to the sheet size, different component sizes can be nested in the cutting program to save material. This allows users to utilize almost all of the raw material. The machine is also equipped with a universal cutting unit with fully adaptive lens system. The focus diameter of the laser beam can be selected as desired. With this flexibility, the TruLaser 3080 fiber effortlessly produces a wide variety of applications. In addition, it achieves very high productivity and quality in all sheet metal blankets, according to Trumpf.
Flexible to use
The machine processes a wide variety of materials, for example, mild steel, stainless steel, copper and brass. Because the TruLaser 3080 fiber easily cuts all part sizes from the smallest to the oversized, companies can use it for a wide range of applications and expand their offerings. In addition to one oversized sheet, companies can also place several smaller sheets on the pallet in the machine. This gives them even more flexibility in production.
Nanojoints: High safety without wasting materials
The TruLaser 3080 fiber has the new Trumpf “nanojoints” technology, which increases productivity and process reliability in manufacturing because it eliminates the need for ridges when cutting components. These “microjoints” usually ensure that the cut part does not tilt during the cutting of the rest of the sheet. The employee does not break it off by hand until he removes the parts from the machine. Because the fractures have to be smoothed at the cut edge, more rework is required. Component removal also takes longer for workpieces with microjoints, since breaking off does not always succeed without friction. Microjoints are not only time-consuming, but also waste material because users cannot arrange the components directly next to each other on the sheet metal panel.
With the nanojoints, instead of a bar, only tiny “breakpoints” are created. Users can thus arrange the parts directly next to each other on the sheet metal panel and thus save material. It also shortens the machining time because the laser creates the breakpoints while it cuts the contour of the part. Reworking is usually not necessary, as the contour injury is hardly visible. Component removal is also much faster, because the employee has to use less force to release the components from the sheet metal panel.
