FiberCut® STa

Laser Mechanisms’ FiberCUT® STa 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. The head features programmable focus position adjustment which delivers exacting cutting in ­materials with varying thickness and fastest possible piercing. FiberCUT® STa’s ­nozzle also senses the required tip standoff from the workpiece and automatically maintains that standoff through its internal drive system.

  • 3-dimensional cutting with fiber-coupled laser for 16 kg robots
  • Up to 30 mm of programmable focus-to-tip ­adjustment
  • Low moving mass minimizes inertia transfer to robot support arm


  • Complete system consists of cutting head, motorized fiber collimator and linear drive with position
    monitoring
  • All wiring and assist gas lines are internally plumbed – avoiding costly snags and breaks
  • Cam-operated drive system with axial crash protection
  • Upper cover glass to protect fiber/collimator optics
  • Cartridge style drawer provides quick and easy ­access to the lower cover glass
  • Provides error signals in case of collision, over-temperature and exceeding the operating range
  • Sealed beam path
  • Multiple gas jet tip options to optimize cutting quality and speed
  • X-Y beam-to-tip centering adjustment
  • Works with all leading fiber-delivered laser ­systems up to 6 kW with wavelengths of 1030-1080 nm
  • Multiple process monitoring capabilities
  • Multiple water-cooling aperture specifications for varying (NA or BPP) lasers
  • Optional fiber clamp
  • Engineered for the harsh factory floor environment
  • Internal, low-noise height sensing system is ­unaffected by cutting plasma or piercing debris
