Laser cutting machines emit high-energy laser beams to cut or etch specific designs on materials such as steel, plastic or wood. It is often used in industrial manufacturing applications and the beam will burn, evaporate or melt away excess product, leaving an excellent finished design or edge.This article is about the basic knowledge about the laser cutting machine and how it works.
The following knowledge points are listed below:
The history of the laser cutting machine
The structure model of a laser cutting machine
The types of laser cutting machine
The use of Laser cutting machine
In 1965, the first laser cutter drilled a diamond mold. This machine is manufactured by the Western Electric Engineering Research Center. In 1967, the British pioneered the laser-assisted oxygen cutting of metals. In the early 1970s, this technology was put into production for titanium cutting in the aerospace industry. At the same time, carbon dioxide lasers were used to cut non-metals, such as textiles, because the energy of the carbon dioxide laser was not enough to overcome the thermal conductivity of metals.
Laser cutting machines have computer numerical control (CNC) and laser optics equipment. Laser optics equipment controls and directs the intensity of the laser beam to achieve the desired design effect, or the specific cutting required in a manufacturing or design project. The laser beam is generated by a process in which an electrical discharge or a lamp triggers the laser material in a closed container, causing a chemical reaction, thereby generating a high-energy beam. Then use a mirror to reflect the light beam in a monochromatic light. From the mirror, light is guided to the work area by optical fibers or mirrors, the narrowest point cut with a beam or the design is etched into the material.
There are three main types of lasers used in laser cutting. The CO2 laser is suited for cutting, boring, and engraving. The neodymium and neodymium yttrium-aluminium-garnet lasers are identical in style and differ only in application. Nd is used for boring and where high energy but low repetition are required. The Nd:YAG laser is used where very high power is needed and for boring and engraving. Both CO2 and Nd/Nd:YAG lasers can be used for welding.
Three types of laser cutting machine are popular these days, they are:
l The CO2 laser cuttng machine.
It is commonly used in cutting and engraving.
l The Nd laser cutting machine.
Nd is short for neodymium, it is used for situation where high energy and low repetition needed.
l The Nd:YAG lasers.
Nd:YAG is short for neodymium yttrium-aluminium-garnet lasers, it is used for conditions where very high power is needed.
Laser cutting machine is often used for precision cutting of engineering machinery parts. For industrial applications, laser cutting machines are commonly used to cut structural and pipe materials as well as flat materials such as metals. CNC settings can also be changed to etched or carved all types of designs on metal, wood and plastic. Professional CAD (Computer Aided Design) software is used to program the CNC and instruct it to perform the cutting, engraving or etching specifications required for laser cutting projects. The size and capabilities of the laser cutting machine determine whether it can be used for small or large manufacturing projects.
Nowadays the laser cutting machine is not only used for industrial manufacturing applications now but also starting to be used in schools, small businesses and other conditions. It is more widely used in the world now. We also provide Laser Engraving Machine, CNC Wood Working Machine, contact us!
