Fiber Lasers
designed and assembled in Poland

Fiber laser cutters are modern machines distinguished by numerous advantages. They are not only an excellent and far more cost-effective alternative to CO2 technology, but also offer many benefits that enable up to 70% higher production capacity and improved quality. FIBER technology allows cutting of sheets and other materials of varying thickness — from ultra-thin to very thick. The wavelength of a FIBER laser is 1.064 µm, resulting in an intensity 100 times greater than that of CO2 lasers of comparable power.

Main advantages of the machine:Fully Enclosed Large-Format Fiber Laser Cutter FIBER LF12025GH / LF10025GH 20000W

  • Maintenance-free fiber source
  • No consumable components
  • Fiber laser source requires 1/3 less installation space
  • High energy efficiency – up to 100,000 working hours
  • Versatile applications (special steels, carbon and stainless steel, copper, brass, aluminum, titanium)

Fiber Laser Technology

  • Increases work efficiency by up to 80%
  • Reduces service costs by 70%
  • Saves up to 80% of energy consumption
  • Minimizes gas usage

Safety and Environmental Protection

  • Fully enclosed laser housing
  • Observation window with certified CE laser protective glass
  • Fumes generated during cutting are filtered inside the enclosure — no environmental contamination




Gantry Structure Made of Aerospace-Grade AluminumFully Enclosed Large-Format Fiber Laser Cutter FIBER LF12025GH / LF10025GH 20000W

The moving gantry is made from heat-treated aerospace-grade aluminum, pressed with a force of 4300 tons, achieving exceptional rigidity. This aluminum alloy provides excellent stiffness (superior to cast iron), low weight, high resistance to corrosion and oxidation, and excellent machinability.

Exchangeable Worktable System

The machine is equipped with a dual worktable system — an upper and a lower platform — both controlled by the CNC software. The exchange cycle of the working platforms takes just 15 seconds, minimizing downtime and ensuring continuous production.




Welded Frame with Honeycomb StructureFully Enclosed Large-Format Fiber Laser Cutter FIBER LF12025GH / LF10025GH 20000W

The welded frame has an internal honeycomb structure made of numerous interconnected rectangular tubes. Inside each tube, reinforcement ribs have been installed to increase the frame’s strength, stiffness, and stability of the guide rail. This design effectively prevents deformation. The high rigidity and tensile strength of the structure ensure up to 20 years of use without distortion.

Raytools Cutting Head

  • Automatic Focusing System – Autofocus. The software automatically adjusts the focusing lens during the cutting process for sheets of different thicknesses. The automatic focusing speed is ten times faster than manual adjustment.
  • Extended Manual Adjustment Range – focus range from -10 mm to +10 mm with 0.01 mm precision, suitable for cutting materials up to 20 mm thick (for laser sources below 1500 W).
  • Extended Service Life. Both collimating and focusing lenses are equipped with a water-cooling system, which reduces the head temperature and prolongs its operational life.

IPG Fiber Laser Source – 20 kW Power

The machine is equipped with a high-power IPG YLS-CUT laser source (20 kW). This industrial-grade fiber laser enables cutting of stainless steel, aluminum, and other metals up to 70 mm thick with outstanding precision and edge quality.

Segmented Smoke Extraction System

The machine is equipped with an advanced segmented fume extraction system. Each section of the bed has a high-pressure fan that captures smoke and dust from all directions. The strong suction efficiently removes fumes, keeps the air clean, and protects the optical lens from contamination.









High-Speed Linear MotorsFully Enclosed Large-Format Fiber Laser Cutter FIBER LF12025GH / LF10025GH 20000W

Equipped with high-performance linear motors, the FIBER laser cutter allows fast and precise cutting of any shape from sheet metal. Extremely high speeds and accelerations, combined with high-resolution feedback systems, provide unmatched performance and accuracy.

A linear motor converts electrical energy directly into mechanical linear motion. The main advantages of linear motor technology include minimized friction, zero backlash, no mechanical transmission losses, and the elimination of positioning errors. The high dynamics of operation are the key to superior efficiency.

Installation of linear drives on all axes guarantees long-term accuracy and consistent performance. These drives require no maintenance and ensure completely wear-free operation.
