4Fiber Laser Cutting Technology
Pump diode modules pumps the light radiation
into the active fiber
Optical active fiber with doped core (ytterbium)
and couble cladding, where the pumped light excites the core
Transport optical fiber bringing out the power

5Comparison between fiber laser
cutting machine and CO2 laserPower: 3kW CO2 Fiber Laser
Laser SystemLaser based on a gas mixture in which light is amplified by carbon dioxide molecules. Diode Pumped Laser with a doped fiber as gain medium where most
of the laser module is made of fiber.
Reflectivity
CO2 lasers are less effective for cutting highly reflective materials, since much of the beam is reflected back towards the source and not absorbed by the substrate. As a result, higher power levels are required for cutting as compared to fiber lasers.
Much less power is required for cutting reflective materials like aluminum or copper since more of the laser energy is absorbed by the substrate. This allows for intricate high quality cutting at higher efficiencies than comparable laser cutting systems.

Light Source: cable from laser diodes with low energy consumption
Active medium: doped ytterbium ions
Active fiber: double coated fiber cable with fiber Bragg grating (FBG)
Wave legnth: 1,0nm (Near-infrared)
Speed: extreme speed in thin sheets cutting
Optical path: the laser beam is delivered through cable, no mirrors
Energy efficiency: 35%
Low operating costs
Low-cost maintenance in the long run
Optimum absorption rate of the beam
Seamless cutting of non-ferrous metals and alloys
Simplified structure
Environmental conditions do not affect the workflow (humidity, dust, vibrations)
Guiding of the laser beam is not necessary
Extended working hours of laser diodes : 100 000 часа
Extra space and an option for laser power upgrade
9Motors and drives in fiber laser
Servo motors
+ rack and pinionLinear drives
Acceleration Speed (G) 1,5G 3G
Axis Speed 120m/min 200m/min
Additional Energy Consumption 0kW/h +20kW/h
Positioning Speed ±0,05mm ±0,01mm
Repeatability ±0,02mm ±0,01mm
Linear drives disadvantages:
› Non-continuous process – they go back to home position every time› High technological but with no adequate after-sales service› Magnetizes and attracts metal dust› High energy consumption› Require an additional chiller
Why does NUKON use rack and pinion driven by servo motors?
› Continuous process of work› Precise and well-tested› After reaching it’s peak the speed is reduced, but it does not affect the
cutting speed at all› Energy consumption optimization

Fiber cable input Protective Glass Collimation module Protective Glass Cartidge
Cutting assembly: Nozzle and adaptor
Designed by NUKON duo consumables for additional protection of the cutting head. Consumables are a subject of amortization and usually they can be changed separately.In rare occasions as a result of heat and other external influences, consumables maystick to each other as welded and they have to be changed together.
The ceramic cover of the adaptor protects the cutting head from damages.
20Cutting head movements
Right choice of a cutting method:› Optimizes the work flow› Guarantees high quality results› Depends on the material type and thickness
Fly cutting:1) Rectangle2) Frog Jump3) Fast Cut
Application:- Serial cutting of details with same shape and dimensions- Details with advanced contours
Movements: linear or parallel
First all the contours from same side are cut than the cutting head moves to the other side and
when finished all contours cut the cutting head makes a frog jump and makes the outline.
When moving from one contour to another the cutting head doesn’t move on the z-axis, but it
moves with a turned off light.
