Laser Mechanisms' FiberCut Right Angle (RA) laser processing head is specifically designed for demanding industrial applications in extremely harsh environments. Engineered for 3-dimensional robotic cutting with a fiber-coupled laser, FiberCut RA is a compact, low moving mass head that minimizes inertia transfer to the robot support arm. All connections to the head enter at a right angle, including the fiber, providing tight access to parts, easy cable routing and stress reduction on the input fiber. The FiberCut RA system consists of the cutting head, fiber collimator, linear drive with position measuring and an internal, low-noise height sense system that is insensitive to cutting plasma or piercing debris. With rugged and effective simplicity, FiberCut RA is easy to maintain and operate in factory floor conditions. FiberCut RA laser processing heads have also demonstrated considerable success in retrofit situations where they have replaced existing laser cutting heads that were costly and difficult to operate.
