Laser metal cutting machines have completely transformed the landscape of the manufacturing and fabrication industries. By harnessing the power of focused laser beams, these cutting-edge machines can make incredibly precise cuts through a wide variety of metals, providing unmatched accuracy and efficiency compared to traditional cutting methods. As technology continues to advance, these machines are continually evolving and improving, solidifying their status as indispensable tools in modern production processes.
The Science Behind Laser Metal Cutting
At the core of laser metal cutting lies the principle of using high-intensity light beams. By focusing a laser beam to a small spot, immense heat is generated. This heat is then used to melt, burn, or vaporise the metal, resulting in clean and precise cuts. The process typically involves a laser generator, a cutting head, and a motion system that guides the laser across the metal surface.
Types of Laser Cutting Machines
There are several types of lasers used in metal cutting, each with its own distinct advantages:
-
CO2 Lasers: These are well known for their versatility and ability to cut through thick metals and non-metals. They work by producing a beam of infrared light that is absorbed by the metal.
-
Fibre Lasers: Fibre lasers generate the laser beam using a solid-state medium. They boast high efficiency, high beam quality, and the ability to cut MS , SS, AL, GI as well as reflective metals like brass and copper.
-
YAG Lasers: YAG (Yttrium Aluminum Garnet) lasers are another type of solid-state laser. They are effective for cutting metals with moderate thickness and are frequently utilised in industrial applications.
