In summary we can say that laser cutting is a process that uses a beam of light of high power to melt the material of a piece allowing cutting and engraving. That is exactly what a laser cutter machine does, in summary.
The laser cutter is the abbreviation in English of Light Amplification by Stimulated Emission of Radiation, for simplicity, we can make a comparison with something that many people have tried at home or at school, which is the joke of generating fire with a magnifying glass, the concept is the same, is to amplify the energy of light to the point of heating the material in a certain region, as well as the joke of the magnifying glass, which amplifies the light of the sun at a specific point.
This beam of light is so dense that it melts and causes the material to evaporate, enabling not only the complex cutting of parts from various materials but also the recording through the regulation of energy and depth. That is the same idea applied to the fiber laser cutting machine. Despite the time of use and maintenance the lasers are still considered low maintenance equipment.
The different types of laser cutter machine
You must be wondering now, are these machines and lasers all the same? The answer is no, with the advancement of technology the trend is to increasingly arise machines with lasers, currently the market offers three main types of laser cutting and engraving check out the below:
Laser gas orco2 laser cutter
This is the type of laser most used, it is used for cutting various materials among them are acrylic, plastic, wood, glass, paper, textiles, plates and films, leather and even stone. The gas laser is a mixture of carbon dioxide with other gases such as nitrogen and helium, which is stimulated electrically, its wavelength is 10.6 micrometers, which allows the work with non-metallic materials. The co2 laser cutter is quite affordable as well. Check here.
Crystal laser or nd: yag, nd: yvo
It is also a solid-state laser, of which the most common lasers are Nd: YAG (Neodymium doped aluminum yttrium) and Nd: YVO (doped with ortho-vanadate yttrium neodymium), its wavelength is 1,064 micrometers, The same length of fiber laser, the difference is the maintenance cost, these types of lasers are more expensive and their time of hours for maintenance ranges from 8 to 15 thousand hours while the fiber laser is 25 thousand hours for the maintenance or replacement of parts.
Fiber laser cutting machine
The fiber laser cutting machine is a more complex machine, belonging to the solid state laser group, where a laser beam is generated or as it is known laser seed, amplified with special glass fibers, the wavelength is of 1,064 micrometers, its intensity is 100 times more than the co2 laser cutter, which allows much more precision in cutting, this laser due to its power is indicated for cutting metals, but also can cut other non-metallic materials.
