Comparison between fiber laser 5 

cutting machine and CO2 laser 

Power: 3kW CO 2 Fiber Laser 

Laser System 

Reflectivity 

Laser based on a gas mixture in which light is amplified by carbon dioxide molecules. 

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. 

Diode Pumped Laser with a doped fiber as gain medium where most 

of the laser module is made of fiber. 

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.

Motors and drives in fiber laser 9 

Servo motors 

+ rack and pinion 

Linear drives 

Acceleration Speed (G) 1,5G 3G 

Axis Speed 7086”/min 7874”/min 

Additional Energy Consumption 0kW/h +20kW/h 

Positioning Speed ±0.002” ±0.0004 

Repeatability ±0.0007 ±0.00043 

Linear drives disadvantages: 

› Non-continuous process – they go back to home position every time 

› High technology with a high amount of 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? 

› Best system for uninterrupted operations/very little service 

› 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

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 may 

stick to each other as welded and they have to be changed together. 

The ceramic cover of the adaptor protects the cutting head from damages.

Cutting head movements 20 

Right choice of a cutting method: 

› Optimizes the work flow 

› Guarantees high quality results 

› Depends on the material type and thickness 

Fly cutting: 

1) Rectangle 

2) Frog Jump 

3) 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. 

Fast Cut Frog Jump Rectangle 

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.
