There are several types of lasers available for cutting materials. You may have heard of CO2 lasers, Fiber lasers, or Pulsed lasers. Read on to learn about each type. There are many advantages to each type of laser. If you aren't sure which is right for your needs, consider getting a laser cutting software program to get started. After reading this article, you should be able to make the most informed decision when it comes to choosing the right laser cutter for your needs.
Moving material lasers
Different types of material require different speeds and powers. For example, if you need to cut a metal surface, you should use a higher power but a lower speed. Conversely, if you are cutting a thin material, you can use a lower power and higher speed. The reason is that lasers use different wavelengths and speeds, and the same power and speed does not work on all materials. Here are some advantages of moving material lasers:
CO2 lasers
CO2 lasers are excellent for marking and engraving on metal surfaces. CO2 lasers have a low power and can engrave most metal surfaces. However, high-power CO2 lasers will not provide satisfactory results because they will produce an uneven engraving with a bad surface finish. A fiber laser marking system is best suited for marking metal surfaces, but cannot be used for engraving on non-metallic materials. Fiber lasers will produce very fine striations in the metal surface.
Fiber lasers
High-powered fiber lasers for laser cutting have many advantages over other cutting technologies. They produce higher production, are cost-effective, and are flexible. This type of laser is effective on a wide range of materials and can be combined with automation for even more versatility. Fabricators can use fewer cutting machines to create a higher volume of finished work. And because of their flexibility, they can easily adjust them to fit their particular needs.
Pulsed lasers
The use of pulsed lasers in laser cutting has several advantages over continuous-wave lasers. While the continuous-wave laser stays on during the cutting process, the pulsed laser turns on and off rapidly. The short pulses release high-energy energy. The pulsing action of the laser gives it most of its benefits. Its lack of a zone of localized heat allows for a cleaner cut and improved edge quality.
Exothermic reaction between metal and oxygen
Oxygen assists the process of laser cutting, causing an exothermic reaction between metal and oxygen. In a laser cutting operation, oxygen impinges on a focused spot and heats the metal, causing it to become molten. The molten metal then exits the area through which the laser beam impinged. Therefore, laser cutting is a high-speed process.
Stealth dicing
One way to create precision cutouts in high-performance semiconductors is to use a laser cutting process for stealth dicing. This technique creates rows of perforations in a thin layer of the SD. This cutting method is extremely gentle on the environment, as the process is dry, reducing water consumption by 622 tons a year. To learn more about this process, read on. Here are some advantages and disadvantages of stealth dicing.
