Laser Machines For Sale
With so many laser cutters for sale in the market today, it can be difficult to decide which is best for 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 include: CO2, neodymium (Nd), and neodymium yttrium-aluminum-garnet (Nd-YAG).
Boring, cutting, and engraving are some of the functions of a CO2 laser. This is considered to be the most common laser cutting equipment used in production and fabrication facilities today because of its versatility. They are most commonly used to cut mild steel, titanium, stainless steel, aluminum, paper, wood, plastic, wax, and fabric.
They function mainly by a current being passed through a mix of carbon dioxide, helium, and nitrogen gasses, but can also be generated using energy created by a radio frequency. The radio frequency is becoming well-known due to the fact that it causes less electrode erosion than the other method.
Nd laser cutters are specially designed for boring functions requiring high energy, This type of machine tool also has a much lower repetition speed compared to the other types of laser machinery.
The Nd-YAG on the other hand is specially made for even higher powered boring, engraving, and metal trimming applications. 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 that is for sale in the market today is the laser micro jet which uses a combination of laser and water jet to cut material. The water jet is used to guide the laser as it cuts, but at the same time it also eliminates debris and cools the workplace during the cutting process. This type of material cutting tool has several advantages over other laser cutting machinery including increased cutting speed, cleaner cuts, and improved fracture strength of cut materials.
Besides the different variety if machines, there are also different types of laser cutting processes that are being used in the industry today. Here are some examples of these processes: reactive and vaporizing cutting, thermal stress cracking, fusion cutting, and silicon wafer stealth dicing.
Reactive cutting 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. The most common use of this method is in glass cutting.
In conclusion, determining the right laser cutter and method will always depend on the material and the requirements of the project.[post-views]
