The usa green laser pointer agreement will be signed next week

Current international evaluation of the quality of laser cutting is not a uniform standard. Affect the quality of laser cutting factors affect the quality of laser cutting many factors, in addition to cutting parameters and characteristics of the workpiece itself, it also with the irradiation power density outside the optical system, the nozzle diameter and distance between the nozzle and the workpiece surface, such as the impact factors. Home and abroad a large number of theoretical studies and experimental analysis, impact the quality of laser cutting of the main factors can be divided into two categories: process performance and light effects; processing of material factors and process parameters. The worker should obey the working table of    green laser pointer    .
Common engineering materials, laser cutting of metal materials, laser cutting low-carbon steel laser cutting laser cutting technology is the most widely used areas. Typically, the thickness of carbon steel in l0mm less oxygen can be carried out to help a good laser cutting. Compared with low-carbon steel, stainless steel cutting required laser power and oxygen pressure are high, and, although the cutting of stainless steel cutting can be achieved more satisfactory results, but it is difficult to obtain completely non-sticky residue of the kerf. As the aluminum on the wavelength of 10.6 um CO2 laser with high reflectivity and thermal conductivity, so very difficult to cut from aluminum alloy. General Manager had a technical discussion meeting to decide the technical program of    green laser pointer      .
The laser cutting requires more than the steel beam to overcome the threshold energy density, the formation of the initial hole cutting process started, once the vaporization cavity formation, it is like steel, like the laser has great absorption rate. According to China has been cutting experience, due to intense chemical reaction and oxidation of titanium, oxygen cutting process can lead to over-burning spray, spray compressed air should be adopted so as to ensure the quality of titanium cutting. Laser Cutting Ti-6Al-4V titanium alloy components, cutting speed, cutting-edge do not need polishing, trimming the bottom of a little sticky residue, it is very easy to remove. Copper alloys and nickel-base alloy of copper and aluminum is similar to the CO2 laser with high reflectivity and high thermal conductivity of copper due to its high reflectivity. The workshop imported an advanced processing machine of    green laser pointer      .
CO2 laser cutting speed is very slow. Brass (copper alloy) to be used when cutting with higher laser power, auxiliary gas using air or oxygen. Nickel-base alloys can be laser cut, with the alloy composition of the different cutting speed is about the same thickness of the cutting speed cutting of stainless steel 0.5-1.0 times. Non-metallic materials, laser cutting. Nonmetallic materials is 10.6 μm wavelength absorption of CO2 laser beam of a good body, because of its small thermal conductivity, heat conduction losses are small, almost all the incident light beam can absorb energy and quickly evaporate the material , in the light spot formed at the initial holes, cutting the process into a virtuous circle. Poor thermal conductivity, and almost no plastic ceramic materials, usually cold, thermal processing is very difficult. The   usa green laser pointer      agreement will be signed next week.
Laser cutting ceramics and metal cutting oxygen to help very different mechanisms, it is controllable fracture orientation. When the laser beam along a predetermined cutting direction when heated in a small area around the points of light caused by direct heating and the resulting gradient generated by high mechanical stress. This high stress that these brittle ceramic materials, the formation of small cracks. As long as the appropriate process parameters and control, cracks along the beam direction of movement will keep strict form, so the material cut. Microelectronic devices such as the use of corundum materials, laser beam with a 250W power can be precisely cut out in the specified parts of the required size, cut-free particles tearing, does not require subsequent treatment. The Production process of    green laser pointer      needs to be under the supervision of the director.
