Fiber versus CO2 laser cutting

As a maker of CO2 laser cutting machines with yield control from 2.2 to 6 kW and genuine fiber laser machines going from 2 to 4 kW, is regularly gotten some information about the advantages of each kind of machine and which is better for explicit applications. Diagrams beneath the advantages and disadvantages of the two advancements.

Amid this time, more than 35 fiber laser cutting machines have been sold by the organization in the UK alone.

Fiber Lasers

Quickly, fiber laser light is made by banks of diodes. The light is diverted and intensified through fiber optic link like that utilized for information exchange. The enhanced light, on leaving the fiber link, is collimated or rectified and afterward centered by a focal point onto the material to be cut.

Production of the light is 200% more proficient than through a customaryCO2 laser, and conveyance is far less difficult, 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 in this way,not a consumable thing.

The advantages of a genuine fiber laser source include:

  • No moving parts or mirrors in the light-producing source, in contrast to a customary CO2 resonator or circle laser. This has an unmistakable favorable position as far as decreasing upkeep necessities and working expenses.
  • A lot higher electrical effectiveness, bringing about impressively bring down 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 it execution.
  • Higher velocities when cutting dainty material. Contrasted and a similar 4 kW CO2 machine, the fiber laser is multiple times speedier in a straight line cutting of 1 mm gentle, excited, or treated steel and twice as quick when cutting 2 mm.
  • A capacity to cut intelligent materials without dread of back reflections harming the machine. This permits copper, metal, and aluminum to be cut without issues.
  • half longer adjusting interims and half lower overhauling costs.

CO2 laser

The impediments of fiber contrasted with CO2 primarily relate with the cutting rate when preparing thicker materials, commonly over 5 mm, where the CO2 machine is quicker in a straight line and furthermore has a lot of quicker penetrating occasions toward the beginning of the cut. There is likewise the upside of a smoother surface complete with the laser machine when cutting thicker materials.

In this manner, what can be found from the measurements and encounters of our UK clients that have purchased fiber and once in a while likewise CO2laser profilers.

  • Over 70% of fiber laser clients are subcontractors, the rest of unique gear makers (OEMs).
  • Of the subcontractors, just 31% had a solitary laser profiler in the wake of obtaining the fiber machine, though 69% were various laser clients and could choose which machine to put work onto, CO2 or fiber.
  • The primary explanation behind buying a fiber machine was the speed of cutting dainty (1 to 2 mm and up to 3 mm) materials.
  • An imperative optional reason was the lower running expense and the lower control utilization utilizing fiber innovation, which was especially critical in organizations at the best end of the electrical supply limit in their workshops. Read more.

Conclusion: CO2 versus fiber

What are the ends to be drawn from this assessment? In rundown, Bystronic UK’s experience so far is that the organizations well on the way to embrace the new fiber innovation are subcontractors, either those that represent considerable authority in cutting slender metal, for example, for purpose of-offer sheet metal work and white merchandise, or firms utilizing a fiber machine’s qualities to supplement CO2 laser machines cutting thicker evaluations of plate.
