As with any kind of technology or process, laser cutting has developed as time goes by not only as another alternative process to some conventional types of cutting, but also to include different techniques and types itself.
Before you understand various laser cutting techniques, it’s essential to look at different kinds of laser cutting. There are 3 main types and these include:
Gas Laser Cutting
More often than not, gas laser cutting is also called CO2 laser cutting, which is done with the use of CO2 mixed laser. This is made as a viable laser through stimulating electrically the said mixture of carbon dioxide. When the gas laser cutting was invented first in the year 1964, it was not powerful enough for cutting metals. Since then technology has evolved and it could cut metals as well, even if it’s still better suited for non-metals. It has 10.6-micrometer wavelength and used in numerous industrial and medical settings. Gas laser cutting uses nitrogen that works well with the metals including aluminum and steel, even if care should be taken to make sure that there’s pure nitrogen. Failure in doing this may cause the metals that you’re working with to be oxidized.
Crystal Laser Cutting
It’s a process that utilizes lasers that are made from YAG and YVO. Such crystals are part of solid state group and crystals enable high powered laser cutting. It may also be used with both non-metals and metals. Crystal laser cutting has also roots dating back to the year 1964, which is created in the same laboratories like gas lasers. The biggest disadvantage of crystal laser cutting is that it’s a costly kit that’s made up from pricey pump diodes. This kind of laser cutting has also shorter life expectancy than some laser cutting machines in the market.
Fiber Laser Cutting
Another kind of laser cutting is the fiber laser cutting, which is the process that some companies use. It has some similarities to the process of crystal laser cutting, in the fact, which optical fibers also belongs to solid state group and it has a 1.064-micrometer wavelength. Seed laser or also referred to as foundation laser gives a laser beam that’s amplified by glass fibers and pump diodes, which result in more stable and stronger laser beam. It may work well with both non-metals and metals and around hundred times stronger than gas laser machines.
The main advantage that fiber lasers provide is that this has longer service life compared to previous 2 laser cutting kinds, which comes in around twenty-thousand hours. It requires little maintenance and requires replacement parts they’re very cheap.
Aside from the different kinds of laser cutting, there are also several types of laser cutting techniques. Every technique may depend on the materials used and the CNC laser cutters you have. So, if you want to know the best laser cutting technique and type to consider, know first about the requirements of your applications to get the best results.
