Laser cutting is used for various purposes and the most common way it is utilized for cutting metals. Whether it is cutting mild steel, stainless steel, or aluminum, laser cutting in Toronto is highly accurate and produces excellent cut quality. It also has very little kerf width, making it possible to cut even the most intricate metal parts. Now, you might be wondering how exactly can a light amplified by stimulated emission of radiation can cut through a steel and other metal plates or parts? We will be detailing the process below.
The laser created by the machine is actually a very intense beam of light that has a single wavelength and in the case of CO2 laser, it is called the infra-red light that is invisible to the naked eye. This beam of light is about three quarters of an inch in diameter and is highly focused on the plate to be cut through the bore of a nozzle of the laser cutter machine. By focusing this beam into a single spot, its heat density becomes so extreme just like what happens when a magnifying glass is focusing UV light into a paper or a leaf. Doing this results in creating a fire.
In the same manner, think of increasing that energy into 6k Watts or more into a single point in a metal plate. You can imagine those sparks of light produced with a highly dense and powered laser cutting through the plate. The part being cut will first be heated by the beam, melted, and then vaporized, leaving a clean cut. When it comes to cutting aluminum or stainless steel, the laser only melts the material and then uses a high pressure nitrogen to blow away the molten metal plate.
Ultimately, the cut quality of laser cutting in Toronto can be affected by many factors, such as modifying the focal point. But once every parameter is controlled properly, laser cutting is a highly reliable, stable, and accurate method of cutting metals and other materials.
