Laser Machines For Sale

It is sometimes difficult to decide which laser cutter is best for your needs with so many choices in the market today. An industrial laser cutter is simply a machine that uses a laser to perform various cutting applications on metal parts.

However, there are many different variations of these machines that are made for different applications. Here are the 3 different types of laser cutters: CO2, neodymium (Nd), and neodymium yttrium-aluminum-garnet (Nd-YAG).

CO2 lasers are specially designed for boring, cutting, and engraving. This is among the most common laser cutting equipment used in production and fabrication facilities today due to its versatility. Cutting mild steel, titanium, stainless steel, aluminum, paper, wood, plastic, wax, and fabric are some of the common uses of CO2 lasers.
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. 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, What makes this type of machine tool distinct from the others is that it has a much lower repetition speed.

The Nd-YAG on the other hand is specially made for even higher powered boring, engraving, and metal trimming applications. This cutter and the neodymium version are very similar to each other. They are often used to process ceramic and various metals.

A laser micro jet is another type of laser being sold in the market today, it utilizes a combination of water jet and laser 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. 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. 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 is very useful when cutting thin and thick materials with 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.

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.
