FiberCUT® RAc

Laser Mechanisms’ FiberCUT® Right Angle, Compact (RAc) laser processing head collimates and focuses a fiber-delivered laser beam and directs it along with cutting gas through its nozzle for optimal metal cutting. FiberCUT® RAc’s nozzle also senses the required tip standoff from the workpiece and automatically maintains that distance through its internal z-axis drive system. The head’s cover glass protects the cutting lens from process debris.

  • 3-dimensional cutting with fiber-coupled laser for 16 kg robots
  • Low moving mass minimizes inertia transfer to robot support arm
  • Right angle entry of all connections, including fiber, provides tight access to parts, easy cable routing and stress reduction on input fiber
  • Nearly 30 percent smaller and lighter than the original FiberCUT® RA
