What is a Laser Cutting Machine and How Does it Work?

Before we get into the nitty-gritty of how laser cutting improves your business, let’s first understand how the technology works. A laser cutting machine uses a high-powered laser beam to melt, burn, or vaporize material. Unlike traditional cutting methods, which rely on physical force or abrasive material, lasers provide a cleaner and more efficient way of cutting metal.

Laser cutting machines typically use either a fiber or CO2 laser. Fiber lasers are more efficient, providing faster cutting speeds and higher precision, while CO2 lasers are better for thicker materials. When you combine high power with advanced software, you get precision cuts that can be as small as a few microns!

Main Components of a Laser Cutting Machine
