The quality of green laser pointer

The classification of laser cutting laser cutting can be divided into the laser vaporization, laser melting, cutting, laser oxygen cutting and laser scribing and control fracture in four categories [5]. Laser vaporization of high energy density laser beam to heat the workpiece, the temperature rose rapidly to reach the boiling point of the material in a very short period of time, the material begins to vaporize, forming steam. Spray speed of the steam, steam emitted from the material on the formation of the incision. Heat of vaporization of the material in general, so requires a lot of power and power density of laser vaporization. Laser vaporization are used for cutting thin metal material and non-metallic materials (such as paper, cloth, wood, plastic and rubber, etc.). Green ray green laser pointer is the most popular product in the national market.
Laser melt cutting laser melt cutting, the metal material melted by laser heating, and then through a beam coaxial nozzle injection of non-oxidizing gases (Ar, He, N, etc.) rely on the strong pressure of the gases in the liquid metal discharge, the formation of incision. Laser melt cutting does not require the metal completely vaporized, the energy required for vaporization cutting 1/10 only. Laser melt cutting is mainly used for the easy oxidation of the material or activity of metal cutting, such as stainless steel, titanium, aluminum and its alloys. Laser oxygen cutting principle is similar to oxyacetylene cutting. It is as a warm-up heat source with a laser as a cutting gas, oxygen and other reactive gases. Blowing out of gas on the one hand and cutting metal effect, the occurrence of the oxidation reaction and emit a large number of oxidation heat. The quality ofgreen laser pointershould be enhanced more.
The other molten oxides and melt blowing from the reaction zone in the metal in the formation of the incision. Generated a lot of heat due to the cutting of the oxidation process, the laser oxygen cutting the energy required to melt just cutting 1/2, while the cutting speed is much larger than the laser vaporization and melting cutting. Laser oxygen cutting is mainly used for carbon steel, titanium steel and heat-treated steel, easily oxidized metallic materials. 4) laser scribing and Control of breakage laser scribing the use of high energy density laser to scan the surface of brittle materials, the material to heat the evaporation of a small slot, and then apply some pressure, brittle materials will be split along the small groove . The laser scribing laser is generally Q-switched lasers and CO2 lasers. It is the performance characteristics of green laser pointer.
Control fracture using laser groove produced by the steep temperature distribution caused by the thermal gradient in the region, local thermal stresses in brittle materials, leading to severe mechanical deformation of the material and the formation of cracks along the small groove in the disconnect. Laser cutting features laser cutting compared with other thermal cutting methods, the general characteristics of the cutting speed and high quality. Specific summarized as the following. Good cutting quality due to the small laser spot, high energy density, fast cutting, laser cutting can achieve good cutting quality. Laser cutting incisions were thin kerf on both sides of the parallel and perpendicular to the surface, cutting part of dimensional accuracy up to ± 0.05mm. green laser pointer will be your best partner.
Cutting smooth surface appearance, surface roughness of only tens of microns, and even laser cutting can be used as the final steps, without machining, the parts can be used directly. Material laser cutting, the width of the heat-affected zone is very small, and kerf material properties in the vicinity are also almost unaffected, and the deformation of the workpiece is small, high precision cutting kerf geometry, kerf shape of the cross-section showing more rules rectangle. The cutting efficiency is high due to the transmission characteristics of the laser, laser cutting machine, generally equipped with multiple sets of CNC table, the entire cutting process to achieve full CNC. Operation, simply by changing the NC program, you can apply to the cutting of different shape parts, both two-dimensional cutting, but also three-dimensional cutting. green laser pointer can also help stargazers find the targeted star that you want to observe.
