The testing center of green laser pointer has the advanced inspecting instrument. Application from the current domestic situation analysis, CO2 laser cutting is widely used 12mm thick carbon steel plate; 6mm thick stainless steel plate and; 20mm thick non-metallic materials. For the three-dimensional space curve cutting in the automotive, aviation industry is also beginning to receive the application. Muqian suitable for CO2 laser cutting of products in general can be summarized into three categories: the first category: technical and economic point of view should not be made from a metal sheet metal dies, especially profile shape of the complex, small-volume, general thickness; 12mm low-carbon steel,; 6mm thick stainless steel, in order to save manufacturing costs and cycle the mold. Has been used in typical products: structural parts of escalators, elevator panels, machine tools and food processing machinery housings, all kinds of electrical cabinets, switchgear, textile machinery parts, construction machinery structural parts, such as large electrical silicon steel. The engineer should describe the result of the appearance inspection of green laser pointer .
The second category: decoration, advertising, service industry with the stainless steel (general thickness of 3mm) or non-metallic materials (general thickness of 20mm) patterns, marks, font and so on. Companies, organizations, hotels, shopping malls mark, stations, terminals, public places in English fonts. The third category: uniform kerf requires special parts. The most widely used packaging and printing industry is a typical part of the die used, it requires the template in 20mm thick wood cut out on the slot width of 0.7 ~ 0.8mm slot, and then embedded in the blade slot. Fashion in the cutting machine to use, good cut of the printed graphics box. China in recent years, a new area of application of oil sieve slit tube. In order to block the sediment into the pump, the wall thickness of the steel pipe 6 ~ 9mm on uniform cut 0.3mm kerf width, cut from the perforation hole diameter not greater than 0.3mm, cutting technical difficulties, has not small production units. Foreign addition to the above applications, is also expanding its applications. Three-dimensional laser cutting system or configuration of industrial robots, cutting space curve, the development of three-dimensional cutting software, to speed up the parts from the drawing to the cutting process. The new production line of green laser pointer will be completed in two days.
In order to improve production efficiency, research and development of a variety of special cutting systems, material handling system, linear motor drive system, at present, the cutting speed cutting system has more than 100m/min. For the expansion of construction machinery, shipbuilding and other industrial applications, cutting mild steel thickness over 30mm, with particular attention to the study of low carbon steel with nitrogen cutting technology to improve the quality of cutting plate incision. Therefore, in China’s expanding CO2 laser cutting of industrial applications, new applications to solve some technical problems in engineering and technical personnel is still an important issue. CO2 laser cutting several key technologies is optical, mechanical and electrical integration, integrated technology. Laser beam parameters, and numerical control machine system performance and accuracy have a direct impact on the efficiency and quality of laser cutting. Especially for high precision cutting of parts or thick, you must understand and address the following key technologies: the focus position control technology: One of the advantages of laser cutting beam of high energy density, the general 10W/cm2. The testing center of laser pointer pen contains four departments.
As the energy density and 4/πd2 proportional to the focal spot diameter as small as possible in order to produce a narrow kerf; the same time and the lens focal spot diameter is also proportional to the depth of focus. The smaller the focusing lens depth of focus, the focus spot diameter smaller. But cutting a splash, too close to the lens away from the workpiece lens is easy to damage, so it is high-power CO2 laser cutting is widely used in industrial applications 5 〃 ~ 7.5 〃 “(127 ~ 190mm) focal length. The actual focus spot diameter of 0.1 ~ 0.4mm between the quality of the cutting, the effective depth of focus and the lens diameter and was also cut material for such a lens with a 5 〃 cutting carbon steel, depth of focus as the focal length of the 2% range, that is about 5mm, so the focus of control relative to the cut surface of the material is very important. to take into consideration the quality of cut, cutting speed and other factors, in principle, 6mm metal materials, the focus is on the surface; 6mm carbon steel, the focus above the surface; 6mm stainless steel, the focus in under the surface. the specific size determined by experiment in industrial production in an easy way to determine the focus position, there are three: Print method: the cutting head from the top down movement, the laser beam in the plastic sheet printing, print the minimum diameter at the focus . The customer visited the new production line of green laser pointer yesterday.
