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. An industrial laser cutter is simply a machine that uses a laser to perform various cutting applications on metal parts.
Although, there are many different variations of these machines designed for different applications. The three main types of laser cutters include: 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.
They can also be generated using energy created by a radio frequency despite being functioned by a current passed through a mix of carbon dioxide, helium, and nitrogen gasses. The radio frequency method is becoming increasingly popular due to the fact that it causes less electrode erosion compared to other method.
Nd laser cutters are designed mainly for boring functions where it requires high energy. Compared to the other types of laser machinery, this type of machine tool 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 cutter and the neodymium version are very similar to each other. They are often used 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. Using this type of material in a cutting tool benefits the user by providing 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. Some of these processes include: reactive and vaporizing cutting, thermal stress cracking, fusion cutting, and silicon wafer stealth dicing.
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. Because of this, materials that cannot melt such as wood and carbon use this as the most common cutting method.
For brittle materials to form a surface crack, a thermal stress crackling is used, this is then guided by the laser. This is commonly used in glass cutting.
In conclusion, determining the right laser cutter and method will always depend on the material and the requirements of the project.
