What Kind Of Laser Cutting Machine We Should Choose? CO2 Or Fiber Laser Cutting Machine?

CO2 laser cutting machine,is a type of laser cutting machine ,espically used for cutting industry like textile cutting ,fabric cutting,wood cutting,metal cutting ,acrylic cutting and etc.Meanwhile,fiber laser cutting machine become more and more popular nowdays in cutting industry .So what kind of laser cutting machine we should choose ?

applications of laser cutter

It depends on the type and thickness of the material you are cutting.Due to the rate at which the material absorbs the laser. You need to choose the right laser for your application.

Different laser cutter for different applications

CO2 Laser

1,Quality – Quality is consistent throughout all thicknesses of material.

2,Flexibility – high, suitable for all material thicknesses.

3,Safety – CO2 laser light (10µm) is better absorbed by the machine frame, which lowers the risk of irreparable damage to the retina. Personnel should not look directly at the cutting process through the acrylic pane in the door as the bright plasma also presents a risk to sight over a period of time. (Similar to looking at the sun.)

4,Beam guidance – mirror optics.

5,Cutting with Oxygen (flame cutting) – there is no difference in quality or speed shown between the two types of lasers.

Fiber Laser

1,Speed – Faster than CO2 lasers in thin materials as the laser can be absorbed quickly with a slight lead in speed when cutting with Nitrogen (fusion cutting).

2,Cost per part – less than the CO2 laser depending on sheet thickness.

Safety – Strict safety precautions must be taken (machine is completely enclosed) as the laser light (1µm) can pass through very narrow openings in the machine’s frame causing irreparable damage to the eye’s retina.

3,Beam guidance – fiber optics.

So from above all, do you know which types laser cutting machine we should choose ? I think you get it ,and what is more,if you need know more or buy laser cutting machine ,please free contract with me !

“Laser” is an acronym for “light amplification by stimulated emission of radiation” and it’s an early example of a “quantum” electronic device. Co-created by several research teams in the late ‘50’s, in their original form, lasers were resonant cavities formed from ruby crystals and gas tubes with mirrored ends. When “pumped” by a high intensity light source or electric current, they amplified light as beams bounce back and forth through the cavity’s “gain medium”, until some of the light escaped through the partially silvered mirror at one end of the cavity. What made the laser useful was not just the power of the emitted light, but its unusual properties, namely high coherence and very narrow spectrum, make it valuable for industry. The coherence keeps the beam from diverging, allowing a lot of energy to be concentrated in a small spot, ideal for cutting and welding, while the narrow frequency has a major effect on cutting performance in some (typically highly reflective) materials.

how CO2 laser cutting machine work

The “gain medium” essential to laser operation can be solid, liquid or gas, and is a major determinant of the laser light frequency. CO2 lasers have two unique properties.They make them ideal for industrial cutting: the first is the wavelength of light, emitting at 10.6um, near infrared, ideal for heating. The second useful property is high efficiency, over 30 percent, exceptional for gas lasers. The combination allows high power and good heating efficiency.

The resonators are housed in a stand alone cabinet with their associated gas handling, optical pumping and cooling equipment, transferring the laser beam through lenses and mirrors to deliver the energy to a single spot for clean cutting or welding. Typically, a movable table translates in two axes under the beam, defining the cut or weld in a material sheet. Metals are ideal candidates for CO2 laser processing because of speed and fast, clean, nearly slag free cuts possible in thinner materials. 6kW power is possible with CO2 technology, although power is not the only important consideration in laser cutting.
