What is a Metal Laser Cutting Machine?
A laser cutting machine for metal is one of the tools which helps cut, carve, or engrave onto metal sheets using a laser beam with pinpoint accuracy. Its operation involves aiming the laser to melt the material in the designated region with clean and precise cuts. These types of machines are frequent in automotive, aerospace, and construction industries due to their speed and ability to work with even the most intricate designs on different types of metals.
Understanding the Basics of Laser Technology
Laser is an acronym that stands for “Light Amplification by Stimulated Emission of Radiation.” This is the basis of the precision and effectiveness of metal laser cutting machines. The technology functions by using a broad medium such as gas, liquid, or solid-state crystals, and stimulating the atoms within to emit photons in a focused coherent beam. Coherent light is essential in industrial works due to its intensity, focus width, and its ability to move over a long distance without losing its shape.
Laser cutting machines use three types of lasers, which include CO2 lasers, fiber lasers, and Nd:YAG (neodymium-doped yttrium aluminum garnet) lasers. Among them, fiber lasers are favored more as they are more cost effective, last longer, and can be used with various types of metals. More recent studies show that fiber lasers have power output capabilities between 500 watts, to more than 20,000 watts, allowing for extremely fast and precise cutting of stainless steel, aluminum, and brass.
Industrial sources also suggest that fiber laser equipment can achieve laser cutting speeds up to 20 meters per minute, based on the material type and thickness. The materials thickness that can be processed range from 0.5 mm to more than 50 mm in some instances, again, relating to the power of the laser. Also, the newly developed control software for the lasers have reduced the amount of unused material cut, improved accuracy to a fraction of a millimeter, and overall productivity boosted. Some systems utilize over 85% unclaimed resources during production.
