Trumpf boosts 3D cutting speed

“It allows us to increase cutting speed by up to sixty percent for sheets up to four millimeters thick,” says Trumpf product manager Ralf Kohllöffel. But that’s not all: BrightLine Speed also consumes around fifty percent less cutting gas per part than conventional laser cutting. What’s more, it makes the cutting process up to fifteen percent more productive with the same laser power, so each part requires correspondingly less energy to fabricate. “Our new cutting technology is faster and uses less gas – and that translates into tangible cost savings and a real boost in productivity for our customers,” says Kohllöffel.

At the heart of BrightLine Speed is a new, Trumpf patented laser light cable (LLK), a special ‘2-in-1’ innovation with an inner and an outer fiber core. A TruDisk disk laser couples the laser light into the LLK and distributes the laser power to the inner and outer cores using a device known as a wedge switch. This allows users to adapt the laser power and beam profile more precisely and flexibly to the thickness of the sheet currently being processed.
