Trumpf has developed BrightLine Speed, a new technology for cutting sheet metal faster and more efficiently. The solution is aimed in particular at the three-dimensional cutting of hot-formed components, such as those used in the manufacture of B-pillars or door frames in automotive production.
“With BrightLine Speed, we can increase cutting speed by up to 60 percent for sheets up to four millimeters thick,” says Ralf Kohllöffel, product manager at Trumpf. Another advantage is that BrightLine Speed reduces cutting gas consumption per component by around half compared to conventional laser cutting. In addition, the cutting process can be 15 percent more productive with the same laser power, which is why correspondingly less energy is required per component. “Our new cutting technology results in noticeable leaps in productivity and cost savings for our customers through more speed and less gas consumption,” says Kohllöffel.
Two fibers in one cable
The central component of BrightLine Speed is a Trumpf-patented 2in1 laser light cable (LLK) with an inner and an outer fiber core. A TruDisk disk laser couples laser light into the LLK and distributes the laser power to the inner and outer cores using a so-called wedge switch. This allows the laser’s power and beam profile to be flexibly adapted to the sheet thickness to be processed better than would otherwise be possible.
