KOIKE's Gantry Fiber Laser Cutting Machine that makes full use of the state of the art technique. From the beginning of development of Fiber Laser technology, KOIKE has been the leader in the fiber laser cutting market for thick plate.
Running cost of Fiber Laser Cutting Machine continues surprisingly, and the excellent oscillation efficiency can reduce significantly the electricity consumption, compared with CO2 Laser. Regular maintenance and replacement of expensive parts, such as mirror and turbo blower, is not necessary, as well as the laser gas.
FIBERGRAPH is specialized in cutting of thick and large plates which is not possible in the fixed-length housing type. Material's heat absorption rate is higher compared to CO2 Laser, providing similar cutting efficiency by low output. In addition, due to the extensive experience and following the standard safety features, safety is kept enough even without the shielding wall.


  • Oscillators are available in 2kW, 3kW, 5kW and 6kW.
  • Piercing time is about 1/2 compared to CO2 Laser.
  • Power consumption of Oscillator and Chiller Unit is 1/3 compared to CO2 Laser.
  • Running cost is about 1/2 compared to CO2 Laser.
  • Effective width/Length can be set.
  • Small changes over time and frequent specifications' adjustment is not necessary.
  • Damage of condenser lens is reduced by installing the protective glass.
  • Shielding covered structure to ensure the non-leakage of laser beam. 
  • Maintainability improved due to the flip-up type of front cover.
  • Cutting quality significantly improved by the Gas Control Function.
  • Mist Function suppresses burning of hard cutting material and continuous cutting, improving the stability.
