NF PRO 620 Fiber Laser Cutting Description

Fiber laser technology opened a new page in the sheet metal processing industry.

Nukon Fiber Laser is manufactured to meet the expectations of a fast pace changing production sphere.

This machine is constructed according to the versatile design of Nukon’s engineers.

  •  The machine can be produced in the following working sheet size options:  78″ x 236″, 78″ x 315″
  • The fiber laser resonator has a module structure (For example, after a certain time in which you have been using a 1kW resonator you can decide to change it to 2kW and you just have to add new modules.)
  • The laser beam is transmitted to the cutting head via a fiber optic cable, without losses. By this means, you can get an excellent cutting quality and accuracy.
  • Easy to use, operator-friendly cutting head control.
  • It’s unique characteristics make it user and environmentally-friendly because of it’s low power energy consumption. Total consumption for 2kW laser is only 20kW.
  • Mechanically robust and rigid main body
  • Conveyor system for discharging slags and materials
  • Auto dual pallet exchange hydraulic shuttle table system
  • System to illuminate the work area is part of the standard equipment

Cutting head

The  cutting head achieves best results in 2D cutting. It is a cutting head especially developed for fiber lasers. It provides cutting edges with defined quality.

For operators of cutting machines, productivity is an important factor for success. The  cutting head fulfills this requirement completely since it can cut metal sheets of different thickness without manual intervention. This is made possible by the special optics of the  cutting head which allows automatic control of focus position and focus diameter (from .002″ up to .005″) by the CNC control unit. In combination with quick focus movements on the work piece, this enables efficient flat-bed cutting and a maximum of productivity. The cutting head is provided with 2 protective glasses, one in front of the cutting lens and one in front of the collimator lens.

Thanks to this structure, the protective glass is brought to a higher position (6.4″) so that the lifespan is significantly extended (up to 3 times). Furthermore, the  cutting head ensures a high cutting quality. The optics have been designed so that the laser induced focus shift is minimized and the reproduction quality is diffraction-limited

The nozzle can be easily adjusted manually in X and Y direction using lockable precision screws

Larger internal gas flow channels ensure a more stable vertical gas flow and thus a higher cutting speed and cutting quality.

Thanks to its modular design, can be ordered different configuration according to specific needs and requirements.

  • Manual focus adjustment
  • Automatic focus adjustment through “Z – collimator module”
  • Automatic adjustment of the focus and depth of the laser beam by “MZ – collimator module”
  • Sensor contamination of lens
  • Focus adjustment position


Fiber laser – the big innovation of today’s technology, with exceptional reliability and high beam quality, has many advantages:

  • High output power
  • High quality of laser beam
  • Less focus larger working distance
  • Over  30% coefficient of efficiency
  • Modular design  „connect and start“
  • Compact, solid and easy to install
  • Low operation costs
  • Flexible and durable fiber optic cable
  • High electrical efficiency
  • Lifespan of the diodes over 100,000 hours
  • Low requirements for cooling

CAD/CAM programming system options

Nukon Fiber Laser using software Radprofile Cut Cad / Cam with its own post processor.
For ease of cutting has many features like auto nesting and machining, calculating the time, micro-joint, total cut and more.
All data for cutting installed in the technological Radan charts. This program is designed for nesting and machining and is installed directly on the CNC, without any adjustment of the cutting parameters.
Radan has some additional features, if it is unable to cut a hole smaller than
(0.019″ by the thickness of the material), it will be marked automatically.
Radan is a fast, modern programming application designed to assist in transferring data from CAD to NC code.

Nukon Fiber Laser uses Lantek Expert Cut CAD/CAM with it’s own post processor.

For ease of cutting it has many features like auto nesting and machining, calculating the time, micro-joint, total-cut and more.

All data for cutting is installed in the technological Lantek charts. This program is designed for nesting and machining and is installed directly on the CNC, without any adjustment of the cutting parameters.

Lantek has some additional features – if it’s unable to cut a hole smaller than 0.019″ by the thickness of the material – it will be marked automatically.
