Fiber versus CO2 laser cutting

Introduction

As a producer of CO2 fiber laser cutting machines with yield control from 2.2 to 6 kW and genuine fiber laser machines going from 2 to 4 kW, Bystronic UK Limited, Coventry, UK, is regularly gotten some information about the advantages of each kind of machine and which is better for explicit applications. As there is frequently some perplexity in the commercial center, David Larcombe, overseeing chief of Bystronic UK, diagrams underneath the advantages and disadvantages of the two innovations.

Fiber lasers

Quickly, fiber laser light is made by banks of diodes. The light is directed and enhanced through fiber optic link like that utilized for information move. The enhanced light, on leaving the fiber link, is collimated or fixed and after that engaged by a focal point onto the material to be cut. Formation of the light is 200% more productive than by means of a customary CO2 laser, and conveyance is far more straightforward, with no costly optical mirrors. The centering focal point, not at all like on a customary CO2 laser machine, is fixed in the cutting head and along these lines, not a consumable thing. Bystronic first propelled its fiber laser in the UK in 2010 as a 2 kW machine, which was quickly trailed by a 3 kW and afterward a 4 kW machine. Strikingly, the 3 kW model stays most well-known, with 60% of UK machines conveyed being of this power.

On the off chance that one looks at the cost to-execution proportion of the various models, the primary cutting velocity advantage of the higher-control 4 kW laser is in mid-extend materials from 6 to 8 mm thick. There are likewise little benefits in thickness limit when cutting non-ferrous materials, ordinarily an expansion of one measure of material. This helps just clients who cut a ton of material in the 6 to 8 mm range or who wish to cover all projections, as it is their solitary laser cutting machine.

The advantages of a genuine fiber laser source include:

No moving parts or mirrors in the light-producing source, in contrast to an ordinary CO2 resonator or circle laser. This has an unmistakable preferred position as far as diminishing upkeep necessities and working expenses. A lot higher electrical proficiency, coming about in significantly lower running expenses. A 3 kW fiber machine utilizes 33% of the intensity of a 4 kW CO2 machine of normal no matter how you look at its execution. Higher paces when cutting slight material. Contrasted and a similar 4 kW CO2 machine, the fiber laser is multiple times snappier in a straight line cutting of 1 mm mellow, aroused, or tempered steel and twice as quick when cutting 2 mm.

CO2 laser

The weaknesses of fiber contrasted with CO2 principally relate with the cutting velocity when preparing thicker materials, commonly over 5 mm, where the CO2 machine is quicker in a straight line and furthermore has a lot quicker penetrating occasions toward the beginning of the cut. There is additionally the benefit of a smoother surface completion with the CO2 machine when cutting thicker materials. Accordingly, what can be derived from the measurements and encounters of our UK clients that have purchased fiber and once in a while additionally CO2 laser profilers from Bystronic? Over 70% of fiber laser clients are subcontractors, the rest of unique hardware makers (OEMs).

Conclusion

This discussion is so frequently on clients’ psyches, said Larcombethat CO2 and fiber laser cutting examinations, introductions, and live tests have been made key subjects in introductions at Bystronic’s last two open houses in the UK, which made enthusiastic discussion.
