Choice between Fiber laser or CO2 laser ?
Hello,
We are searching for new Laser machine. Now we are having Trumpf 4KW CO2 laser machine. We are cutting more than 95% mild steel and hardox in thickness range from 0,12in (3mm) to 0,79in (20mm). In future we would like also like to cut 1in (25 mm) on the laser so we are thinking about 6 KW laser machine. Now is very popular fiber technology but we don't know if this technology is also so appropriate for thick mild steel..or we rather stay on CO2 technology ? Does anyone have experience with 6KW fiber lasers ? Does it CO2 technology abandons? How is with the cost comparison between fiber and cO2 laser if someone has some data maybe ? And then also possibility of cutting mild steel with nitrogen in lower thickness range, fiber lasers have high speeds in this case but what is with the gas consumption ? And how is with spare parts with fiber lasers and maintenance is it cheaper than by CO2 lasers and how much ? Maybe has someone experience with these things and can help with some advice or data...and which company you recommend ?

Main features and advantages of fiber laser cutting machine:
1. fiber laser electrical to optical conversion efficiency is high, conversion efficiency of more than 30%, the small power fiber lasers without to be equipped with chiller, air-cooled, greatly reduce the power consumption, save operation cost, achieve the highest production efficiency;
2. the operation of the laser only requires power, no need to generate additional gas laser, with the lowest operating and maintenance costs;
3. fiber laser by semiconductor module and the redundancy design, resonant cavity free optical lens, does not require bootstrap time, with adjustment free, maintenance free, the advantages of high stability, reduce the cost of spare parts and maintenance time, which is unmatched by traditional laser;
4. fiber laser output wavelength of 1.064 microns is 1 / 10 of the CO2 wavelength, the output beam quality, high power density, is very conducive to the absorption of the metal material, has excellent cutting and welding ability, so that the least cost of processing;
5. the whole optical routing optical fiber transmission, does not need the complex mirror and so on the light guiding system, the light path is simple, the structure is stable, the outside light road maintenance free;
6. the cutting head contains a protective lens, the focusing mirror and other precious consumable few consumption;
7. the light through the optical fiber are derived, the design of mechanical system is very simple and very easy to work with the robot or multidimensional integration;
8. after a gate coupled with laser multi machine, light through the optical fiber, divided into multi Taiwan work at the same time, the function is easy to expand, upgrade convenient and simple;
9. fiber laser has the advantages of small size, light weight, position mobile, small area;
Re: Choice between Fiber laser or CO2 laser ?
CO2 lasers, while not as fast as their fiber cousins, are extremely flexible and adaptable for use on the most common types of materials, such as aluminum and steel, and on a range of material thicknesses. Although this may change over time, today’s CO2 lasers will generally perform better than fiber lasers on thicker materials, which is an important consideration for any fabricator who is considering the purchase of a new laser. If their projects doesn’t generally involve more intricate work on thinner metals, then putting the extra capital toward a fiber laser may not make much sense.

Or you can think about import from China , then price will be better and also now the fiber machine is mature in China too
more questions you can ask me

Hello thereC02 technology offers you a greater degree of freedom and hence can be used on a wide range of materials. However, Fiber lasers are cheaper to maintain and more environmental friendly and are more suitable for cutting steel than the CO2 lasers. You can check out https://www.heatsign.com/products/fi...arking-machine for more information on these laser technologies to further help you guide your choice. They have a very informative blog too.
