There are two different kinds of lasers used for laser cutting. They are known as CO2 lasers and fiber lasers, but the majority of laser cutters available to consumers and small business owners are CO2 lasers. Those who are wondering how a co2 laser cutter works can read on to find out the basics of what makes a CO2 laser run and how they are used to start learning about these products.
How They Work
CO2 lasers are gas lasers that create a column of extremely high-intensity light using a special lens or a curved mirror. This light is often bounced around inside the machine before it reaches the cutting surface, which allows it to become even more focused. The reasoning behind this process is that focusing the beam of light down into a single point will create a heat density so high that it will cut through most organic substances.
How it Cuts
The incredible amount of heat produced by the pinpoint light beam when it gets to the cutting surface is so hot, it is able to melt or even completely vaporize the material being cut. This provides impressive precision cuts and reduces the possibility of damage to other parts of the material being cut.
As noted above, there are two different kinds of lasers used for laser cutting. CO2 lasers are generally more affordable, though, and they are able to process a wide variety of materials. The only reason a consumer would really need a fiber laser is if he or she needed to cut or mark reflective metals, as CO2 is not able to perform this task efficiently.
What to Look For
Although CO2 laser cutters are typically much less expensive than their fiber alternatives, a laser cutter still constitutes a serious investment for most consumers and small business owners so it’s important to keep a few things in mind when choosing a laser cutter. Always buy from a reputable company and make sure that tech support is available in the event that something goes wrong. Consumers should also make a point of clarifying all of their options prior to placing their orders since there are often lots of extras that cost more money but also make the machines easier to use.
