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.

8Fiber laser cutting technology advantages


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.
