How many laser cutting classifications do you know? Sheet metal processing factory to tell you

Professional sheet metal processing plant in the laser vapor cutting using high energy relative density of the laser beam to heat the product workpiece, so that the temperature rises rapidly, in a very short period of time to achieve the melting point of the material, the material gradually vaporized, producing steam. This steam is ejected at a very high rate, and at the same time as the gas is ejected, a wound is created in the material. The heat of vaporization of the material is generally very high, so laser vapor cutting requires a very high output power and power. Laser vapor cutting is mostly used for cutting extra thin metal materials and non-metal materials (such as paper, cloth, wood, plastic and rubber, etc.). Stretch laser melting cutting laser melting cutting, with laser heating to make the metal material material melting, and subsequently according to the laser beam coaxial output nozzle gas generator non-air oxidizing gas (Ar, He, N, etc.), by virtue of the strong working pressure of air to make shape memory alloy discharge, to produce a wound. Laser melting cutting does not need to make the metal material completely vaporized, CNC punching sheet metal processing requires only 1/10 of the kinetic energy of vaporized cutting.

Laser melting cutting is mainly used in some materials that are not easy to air oxidation or vibrant metal cutting, such as stainless steel plate, titanium, aluminum and metal. Telescopic laser O2 cutting laser oxygen cutting basic principle is similar to oxyacetylene cutting. This is done by using laser as the heating pyrogen and vitality vapor such as oxygen as the cutting vapor. The vapor out of the gas generator on the one hand and cutting metal material efficacy, oxidation reaction, release a lot of air oxidation heat; on the other hand, the molten metal oxide and molten material from the reflection area blow out, in the metal material to produce trauma. Because the redox reaction in the cutting situation generates a lot of heat, so the force necessary for laser O2 cutting is only 1/2 of melt cutting, and the cutting rate is far greater than laser vapor cutting and melt cutting. Laser O2 cutting is mainly used in carbon steel, titanium alloy and its heat treatment process steel and other metal materials materials that are easy to air oxidation.

Stretching laser sheet area and manipulation of rupture laser sheet area is the use of high-efficiency energy relative density of the laser in the ductile material on the exterior of the scanner, so that the material volatile heat issued a small groove, and then increase the aviation sheet metal processing parts a certain pressure, the ductile material will crack along the small groove. The lasers used for laser sheet area are generally Q power switch lasers and CO2 lasers. Manipulated rupture is to use the treacherous temperature distribution caused by the laser when carving the groove to form a partial internal stress in the ductile material, which causes the material to break along the small groove.
