Laser Machines For Sale
With so many options for laser cutters being sold in the market, it can be hard to decide which would best meet your needs. The function of an industrial laser cutter is to perform various cutting applications on metals parts
Although, there are different types of these machines that are specially designed for different applications. The three main types of laser cutters are CO2, neodymium (Nd), and neodymium yttrium-aluminum-garnet (Nd-YAG).
The functions of CO2 lasers include boring, cutting and engraving. This is among the most common laser cutting equipment used in production and fabrication facilities today due to its versatility. They are often used to cut titanium, stainless steel, aluminum, mild steel, wood, paper, plastic, was, and fabric.
Even though they function mainly because if a current being passed through a mix of carbon dioxide, helium, and nitrogen gasses, they can also be generated using energy created by a radio frequency. Because the radio frequency method causes less electrode erosion compared to other method this is becoming increasingly popular.
For boring functions where high energy is required, it is best to use Nd laser cutters. What makes this type of machine tool distinct from the others is that it has a much lower repetition speed.
Nd-YAG is specially designed for even higher powered boring, engraving, and metal trimming applications.If are in need for a higher powered boring, engraving, and metal trimming, it is best to use the Nd-YAG. This type of cutter is very similar to the neodymium version.This type of cutter has similar qualities with the neodymium version. Their main functions are to process ceramic and various metals.
Another type of laser cutter being sold out there is the laser micro jet, this laser utilizes a combination of water jet and laser to cut material. The functions of a water jet is not only limited to guiding the laser as it cuts, it is also used to remove debris and to cool the workplace during the cutting process. There are a lot of advantages by using this type of material in a cutting tool, some of which are increased cutting speed, cleaner cuts, and improved fracture strength of cut materials.
In addition to the different types of machines, there are also a lot of laser cutting processes used in the industry. Reactive and vaporizing cutting, thermal stress cracking, fusion cutting, and silicon wafer stealth dicing.are some examples of these processes.
Reactive cutting basically uses a laser beam to cut similarly to that of an oxygen torch. This process can be used to cut thin and thick materials with pretty low amounts of energy.
Vaporizing cutting on the other hand uses a focused beam of energy essential to heat the surface of the workshop to a melting point.Another process that uses a focused laser beam of energy to heat the surface if the workplace to a melting point is vaporizing cutting. For this reason, materials that cannot melt such as wood and carbon commonly use this cutting method.
Thermal stress crackling is used on brittle materials to form a surface crack, this is later on guided by the laser. Glass cutting is the most common use of this method.
In conclusion, determining the right laser cutter and method will always depend on the material and the requirements of the project.
