It enables laser cutting of round tubes, square tubes, rectangular tubes, open profiles, and special profiles—a laser machine designed for maximum productivity during production changeovers. The challenge: a 6kW fiber laser for a wide range of metal processing tasks! Unmatched laser cutting performance High axis speeds and accelerations, paired with a stable mechanical structure, ensure superior cutting performance and accuracy. The tube and profile laser processing machine for your production—compact, space-saving, simply clever! Smart solutions 100% made in Saxony! Tubes and profiles from 15 x 15 up to 160 x 160 mm 3D cutting with efficient fiber laser technology The semi-automatic 6-fold profile tube loading chain system allows for quick job changeovers. With the optional bundle loader, you work independently. The Bevel Cut A feature that changes everything. Our machines can swivel the cutting head on an additional fifth axis up to 50°, which solves one of the greatest challenges in modern profile processing. Iaodpfx Alsrh Iw Tjcjt When the laser beam always strikes the workpiece perpendicular, it results in an elliptical cut edge. With the option to tilt the tube laser cutting head, it is now possible to achieve a perfect bevel cut in combination with the feed axis. Of course, safety is paramount when operating the skyTUBE Laser! The skyTUBE Pro is a Class 1 laser system. There is no risk of exposure to laser emission or reflection during operation. For all our laser systems, absolute safety and compliance with the highest standards and regulations are fundamental.
