Classification and application of laser cutting machine

Co2 Laser cutting machine the use of higdensity of the focused laser beam the workpiece in the irradiated material rapidly melting, vaporization, ablation or achieve ignition, while the high-speed air stream coaxial with the beam by means of blowing molten material, enabling the workpiece cut open. Laser cutter is one of the thermal cutting methods. Laser engraving machine for sale can be divided into laser vaporization, laser melting cutting, laser cutting oxygen, laser scribing and breaking four types of control.


⑴ laser vaporization.
Laser vaporization is the use of high energy density laser beam heats the workpiece, the temperature rose rapidly, within a very short time to reach the boiling point of the material, the material begins to vaporize, forming a vapor. These vapor discharge rate is large, the vapor ejected while forming a cut in the material. Laser vaporization used for cutting thin metal materials and non-metallic materials.

 


⑵ laser melting cutting.
When cutting laser melting, the metal material is heated by laser to melt, and then by blowing a non-oxidizing gas (Ar, He, N2, etc.) of the nozzle coaxial with the beam, so that rely on a strong pressure of the gas discharged liquid metal, forming a cut. Laser cutting does not require metal melting completely vaporized, vaporization energy required only 1/10. Laser cutting is mainly used to melt some of the cut material or activity is not easily oxidized metal, such as stainless steel, titanium, aluminum and its alloys.

 

⑶ Laser oxygen cutting.
Laser oxygen cutting principle is similar to oxyacetylene cutting. It is used as a preheating laser source, with oxygen and other reactive gas as cutting gas. Blowing out gas on the one hand and cutting metal, the occurrence of the oxidation reaction and emit a lot of heat of oxidation; on the other hand the molten oxide and melt blown out from the reaction zone, a cut in the metal. Because of the cutting process of oxidation reaction generated a lot of heat, so the oxygen cutting laser energy required to melt just cut 1/2 to cut much faster than the laser vaporization cutting and melt cutting. Laser oxygen cutting is mainly used in steel, titanium steel and heat treatment of steel and other metals easily oxidized materials.

 


⑷ laser scribing and control fracture.
Laser scribing is the use of high energy density laser scans the surface of a brittle material, and the material is heated to evaporate a small groove, then apply some pressure, brittle material will split along the small groove at.

Read the above description, I believe we all know the application of laser cutting technology it, if there do not understand, you can consult fully automatic laser cutter machine of professional and technical personnel, will be able to solve your problem. I hope this information can help to everyone.
