Small UV laser cutting machine _ Qingdao Tianrun High Frequency (certified) _ UV laser cutting machine provided by Qingdao Tianrun High Frequency Electric Co. Qingdao Tianrun High Frequency Electric Co., Ltd. (www.gaozhoubo.com.cn) is specialized in the "high-frequency induction heating equipment, ultrasonic plastic welding machine, welding machine, laser cutting machine" of the enterprise, the company of "honesty, hard service "concept, to provide you with the highest quality products and services. Welcome to inquire! Contact: Yan Lidong. Generally UV laser cutting machine manufacturers, laser cutting quality can be measured by the following six criteria. 1. Cut the surface roughness Rz 2. dross incision size 3. Trimming squareness and inclination u 4. After cutting edge fillet size r 5. striped volume drag n 6. flatness F laser is a light, and Nature other luminous body, is made of atoms (molecules or ions) transitions generated, and is caused by spontaneous emission. Although the laser light, but it is obviously different from ordinary light in the first laser only a very short time depends on the spontaneous emission of ultraviolet laser cutting machine, after which the process is entirely determined by the stimulated emission of radiation, so the laser has a very pure color, almost No divergence directivity, high luminous intensity. Laser also has a high coherence, high intensity, high directivity, laser light after passing through the laser generated by the mirror and impinges on the mirror by aggregating the processing items, so that the processing object (surface) exposed to strong heat and rapid temperature increases, so at this point due to high temperature and rapid melting or vaporization with the laser head running track to achieve the purpose of processing. Laser processing technology in the advertising industry can be divided into: laser cutting, laser engraving work two UV laser cutting machine supply, for each work, we have a few different places in the operating process. Several key technology of laser cutting machine is light, mechanical, electrical integration of the integrated technology. Laser cutting machine parameters, performance and precision CNC machines and laser beam systems have a direct impact on the efficiency and quality of laser cutting. Especially for high precision cutting or greater thickness of the part, must understand and resolve the following key technologies: a focus position control technology: One of the advantages of laser cutting is a high energy density beam, usually 10W / cm2. Since the energy density of 4 / πd2 proportional, so focus spot diameter as small as possible, so as to produce a narrow kerf; while the depth of focus is proportional to the focal spot diameter and also the lens. The smaller the depth of focus of the focusing lens, the smaller the focal spot diameter. But there is splashing cutting lens from the workpiece too easy to damage the lens, it is generally high-power CO2 laser cutting machine is widely used in industrial applications 5〃 ~ 7.5〃 "(127 ~ 190mm) focal length. The actual focal spot diameter of 0.1 to 0.4 between mm. For high-quality cutting, the effective depth of focus has been cut and the lens diameter and material related to, for example by cutting carbon 5〃 lens, the focal depth of the focal length range within + 2%, ie about 5mm. Therefore control focus position is very important with respect to the surface of the cut material is to take into consideration the quality of cutting, the cutting speed and other factors ultraviolet laser cutting machine, in principle, the metal material of 6mm, the focus on the surface;. Steel 6mm, the focus on the surface; 6mm stainless steel, the focus of specific dimensions is determined by the experiments below the surface.
