锐星激光在各个行业的应用（Application of sharp Star Laser in various industries） 锐星激光在各个行业的应用(Application of sharp Star Laser in various industries) Applications of laser machines in various processes In order to be familiar with and master the engraving machine operation method and process requirements, the processing technology for each industry made a simple summary. A large area engraving machine, the greater the engraving area, the corresponding engraving effect will be a little bit worse. Because the longer the beam of a large engraving machine, the more serious resonance (vibration). Half cut is a more complex process, often used in the industry, fabrics, mobile phones, buttons, reflective materials, and so on. Requirements of the flatness of the bottom board is also very high, the general use of domestic tubes can also meet the flexibility requirements. Specific engraving speed and light intensity, different materials for different users, the parameters are not the same, the general situation is: 1, carton packaging industry (rubber board) The main use of rubber engraving is YM series, generally use 50mm focusing lens, the format adopts PLT and BMP two kinds. PLT is mainly used for hooking. The two formats have their own advantages, and the specific situation is analyzed. When the carving of the word height is more than 10mm or pattern strokes than 1.5mm, you can use crochet, a show of 7mm single common rubber version for example, hook side surface wetting newspaper, with air jet cup, prevent blowing large wet newspaper blown up, so that the hook out of the line more delicate. At this point, the speed of the general adjustment is: 0.5-0.8 M / min. The faster the rate, the greater the sawtooth; light intensity adjustment is: 20%-50%. As the depth varies, if it is deeper, the light intensity is up to 60%-70%. Double layer rubber version is: 4mm double deck rubber version, light intensity of 1.5mm depth, the speed is generally transferred to 0.5 meters / min. the light intensity is 45%, depending on the specific circumstances. If you carved the word height is less than 10mm, this sculpture is generally used, generally at speeds of adjustment: 10-15 M / min; the intensity adjustment for the top depth of 18%-28%, depth of 55%-75%, the slope of 0.8-1.5, the resolution is 500-600dpi, more or less dense text, light intensity also should be relatively small, slope setting the more small. 2, cloth embroidery industry Cloth cutting machine CM or destroyed by high speed TM series, generally used in the 50mm focusing lens, single cutting normal speed is 5 m / min, the intensity is 40%, the pump power size, cellular good flatness, the size of the light intensity will affect the fabric damage effect. The greater the light intensity, the greater the thermal radiation, light and thin will produce a gap. At present, the biggest problem is cutting yellowing phenomenon, the cloth flat on the honeycomb on the floor, open the exhaust fan, time off dust, prevent the dust generated during the cutting and the cloth smoked yellow, open air compressor, air blowing to ensure rural fruit blown away, cutting the impurities in volatiles and soot blowing gas using an inert gas (such as nitrogen is more ideal). (1), cutting fabric (non-woven, silk, dacron, polyester, satin, twill cloth etc.) belongs to the thin material, in order to ensure the effect of incision, we generally use 50mm focusing lens, spot fine, small cutting slot. Turn on the outside of the laser machine (ventilation, blowing), and then spread the cloth evenly on the honeycomb bottom board. Speed: large graphics or external smooth curve part can adopt high speed CM machine as an example, generally 3-10 meters per minute; small graphics or graphics inside the curve or corner much part of the low speed, generally 0.5-3 meters per minute, light intensity is high: the matching principle with large intensity, low speed distribution small light, general adjustment time is 30-60; speed is 18-35%, and the size of light intensity difference, generally about 5-15%, in order to achieve the matching of cutting line and curve acceleration and deceleration when the size of the light intensity. (2) special cutting cloth (cotton cloth, dust-free cloth, cloth and plastic components containing PC etc.) process requirements: white cotton requires cutting non yellowing, discoloration, dust-free cloth after cutting incision is not hard, for these two types of cloth, we want to use the 50mm focus lens is the best imported frequency laser at to ensure the quality and stability of the spot. Turn on the air and blow (cut the air compressor when cutting the white cotton), and conditionally recommend the use of nitrogen. Speed: 1.5-3 M / min, light intensity: 20-30%, due to the implementation of non yellowing and incision constant hard, we must use the appropriate light intensity, medium speed cutting, too fast speed we must increase the intensity, it will cut due to high temperature and strong light burning or discoloration hardened, too slow light stay when in the long incision, can not achieve the desired effect. As far as the equipment and process are concerned, it is difficult to perfect the process. Especially the thicker white cotton, the incision will change color, and the dust-free cloth will appear slightly stiff. (3) the cutting of double layer cloth (adhesive) (the upper layer is cut through and the next layer is not damaged or slightly damaged) This is the electronic industry processing technology, the laser light control accuracy, stability and light intensity speed matching has higher requirements, at present we generally use domestic glass tube proofing, Basically can achieve the effect, but for mass processing, it is recommended to use imported RF laser. Open the air, blow the cloth evenly on the honeycomb, and adjust the flatness of the four corners of the honeycomb panel. The speed of light: set specific parameters depending on the material, both to achieve a better match on the line, generally on a layer in 1.5-6 meters, the intensity is about 18-35; the intensity of speed under a layer of no specific requirements, in the premise to ensure the good quality of the incision can be a bit faster, also has the difference to set the intensity, so as to guarantee the realization of cutting depth in the deceleration time consistent. (some materials do not blow.) (4) cutting the trademark weaving (cloth, woven label, trademark) We are currently the main label cutting by automatic and semi automatic camera manual cutting of two kinds of working mode, the adjustment and the positioning precision depends on the precision of the machine, each label out there are some differences, each completely impossible to cut the border. We used for cutting requirements with the ordinary cloth cutting almost, but due to label in precision and hardness than the cloth is much greater in intensity and speed have great difference. The speed and intensity are determined by the specific workpiece. The reference parameter is speed 1.2-5 M / min. the light intensity is 20-55%. 3 、 cutting and engraving of acrylic There are many kinds of organic glass materials, import and domestic difference is very large, imported plexiglass cut out very smooth, and some domestic impurities too much, will bubble. Acrylic cutting generally adopts low speed machine, because the laser tube power is not very large, and thin material precision requirements are relatively high. General speed is not more than 3 meters / minute, such as CMB series, linear guide produces fine lines, smoothness is good. At present we have five focusing mirrors that focus on focal length (50mm\63.5mm\75mm\100mm), together with a double focus mirror. According to material thickness introduction: Thick material cutting (10-20mm) 10mm above organic glass generally use 75mm focusing mirror, 25mm above organic glass using 100mm focusing mirror, the deepest can cut 32mm plexiglass. 10mm plexiglass cutting: cutting speed is generally 0.08-0.12 meters / min, light intensity 60-70%. At 60% light intensity, the most stable gas leak jet cup regulates the flow of gas and makes the edge smoother. Because of the larger blow, the molten material is blown back to the organic glass at the cutting point to form a smooth surface. Try to wind down. Sometimes, customers need to add paper or film and cutting, the wind can not be too small, otherwise it will fire. When cutting plexiglass, the speed and intensity must match. The slower, the smoothness is not the better. The organic glass with 15mm above is best to use imported high-power laser. Organic glass engraving with air jet cup, don't try to carve too deep, too deep carving is difficult to reach the bottom roughness, more gas will affect the carving edge effect, to carve more fine and clear, not too deep and blow, acrylic engraving note is set if the output resolution, BMP format in general, the resolution to more than 600dpi, the velocity is 8-18 M / min, the light intensity was 20%-30%, when cleaning the bottom blowing off more smoothly. Cutting of thin material (2-10mm) Organic glass below 5 mm by 50mm focusing mirror, cutting speed is generally 0.35-0.8 meters per minute, the light intensity was 45-65%, 5-10mm organic glass commonly used 63.5 mm focusing mirror, cutting speed of 0.15-0.3 M / min, the intensity of 50-75%, a large area of engraving machine, carving out if the resonance is more serious (the vibration will cause), engraving machine precision is reduced, so the organic glass cutting type format as not more than 1 meters, have some white powder and organic glass carving figures in the process of image, and thus feel clearer, if water carving to erase, appear more fuzzy. It depends on what kind of processing it takes as a concrete result. The carving of glass (or mirrors) For some real glass carving, carving out some customers frosted effect on the glass, but a place will be broken, so the speed and intensity are very demanding. The average speed is 10 meters per minute, and the light intensity is 35%. Mirrors are usually engraved with metal marking machine, the bottom is more delicate and smooth. 4 cutting and carving of wood Wood carving is mainly used in the die cutting board, wood veneer parquet, hanger model, sculpture, wooden frames and so on. Plywood materials, plywood, solid wood, MDF, the current application of the most cutting is plywood. General plywood to distinguish 3mm, 5mm, 7mm, these can be cut, the normal 3mm plywood like speed in 1.2 meters / min can cut through, some solid plate can cut 10mm. Specific circumstances depending on the material. 6mm die cutting board, it is best to use 63.5mm focusing mirror, the speed is 0.2-0.4 meters / min. the light intensity is 75-80%, With a large air pump or air compressor, the effect is more satisfactory. Wood model cutting in general thickness of 3 mm below, the general speed is 0.5-1.2 meters / min.. Parquet veneer cutting with double focusing mirror, high requirements of customers, try to use RF tube. Because the radio tube spot is exquisite, the kerf is tiny. Clothes rack carving - when engraving, it is best to use a small area engraving machine. Wood engraving, according to the size of the graphics, the effect required to set the machine speed. Some customers want to carve more black, you can choose to carve away from focus. The size of the pump affects the degree of burning. Cutting and carving drilling drilling template template, all kinds of commonly used materials are: paper cutting, drilling, carving with (MDF) or thin acrylic paper cutting, we generally use the 50mm focusing mirror, open blowing and suction, the cardboard flat adsorbed on the honeycomb, the cutting parameters and machining process is not what special requirements, due to the cutting part pattern is not too large, the average speed is 0.5-3.5 M / min, the light intensity value is generally about 18-40, as much as possible to increase the air, reduce incision edge discoloration. Hot plate engraving speed at 10 meters per minute, the intensity of 35%, over 600 DPI resolution. Depending on the size of hot drilling, drilling the drilling, the thickness of thick, we need more deep carving board 5 、 leather cutting and engraving Leather is mainly used for vamp carving, handbags, leather gloves, bags and so on. Some of the production process of small holes, surface hook line or cutting patterns, process requirements: hook line surface is not yellow, carved material background, leather cutting edge is not black, carving must be clear. The materials are synthetic leather, PU leather, PVC artificial leather, leather wool, semi-finished products, and all kinds of leather fabrics and so on. Engraving speed depends on the size of the graphics, small pattern line speed is relatively slow, the speed is 0.8 meters / minute, big pattern cutting speed is 1.5-3 meters / min. the light intensity is 75%, and the average leather can be cut through. Leather cutting slightly slower speed in 0.4-1.2 M / min, the intensity in 60-75%, leather cutting incision will be black, cut the air, but the incision will form the oxide layer, the dermis requirements such as incision not black, it is difficult to meet the requirements; all must be processed, such as cutting out can use plasticine the edge of the black with go. There are also cut out peculiar smell, so far, there is no way to solve. The use of nitrogen cutting requires the use of high-pressure nitrogen, slow speed, high cost, but cutting oxide free, cutting effect a little better. Different leather materials, the choice of different cutting methods, such as artificial leather marking, you can first wet water before marking, the effect is more satisfactory. Leather cutting surface can be added to the United States and India paper, to prevent the yellow surface, black edges, the need for special treatment. 6 、 double shade engraving and cutting Depending on the color of the material, the same figure of the image is painted in black and white on two pairs of colored plates to produce exactly the opposite effect. Engraving generally use 50mm focusing mirror, usually resolution at 350-500dpi, the speed is generally 8-20 meters / min. the light intensity 20-30%, the size of the air pump affects the degree of engraving burning. Blowing more carving effect increasingly blurred, so it is best not to blow off in the jet cup {not the case will blow the gas mouth by carving. Double color plate cutting will be dissolved, the edge will be black, are subject to the edge of blade scratch processing}. The speed is 1 meters / min. the light intensity is 50-60%. Sometimes it can be added with film cutting. After cutting, the film will be torn off and the edge surface will be better. 7, lighting engraving and cutting Lighting materials: basically PVC, with surface cloth, but also with paper. Manufacturing process for a drilling, carving, cutting flower and so on, some need to defocus painting line, has cut flower shape, depending on the size of the general graphics, cutting speed at 1.5 m / min, the intensity in 45%, the pump or compressor, are not the yellow edge. Engraving in the general 15 meters / min, light intensity of 30%, resolution in the 200dpi have reached the bottom level. 8 marble carving The general use of black marble material, not what noise. Thus, after the image processing, carved characters clear image. Engraving speed is 8 meters / min. the light intensity is 40%, the resolution is 600dpi, and the net line is 45 lines / inches. 9, cutting paper (paper, film, mobile phone card etc.) Paper cutting generally use small models, double focus mirror, because smoked paper is relatively thin, graphics will be relatively fine, the most appropriate pump, radio tube can be more ideal. Mobile phone button film is also more customers, generally used for proofing. Usually small models, equipped with 50mm focusing mirror. The speed is 0.5-1 meters / min. the light intensity is within 35%. The graphics and sizes are basically changed by modifying the drawings. The size of the cutting seam is added. But the flatness of the honeycomb panel is also very high. 10, cutter template cutting The blade of the cutter is mainly 0.45mm and 0.7mm, and the requirements of the knife seam are strict, and the width of the seam is required to be basically the same as the upper and the lower of the two. The material is MDF and a 6mm rubber sheet, these materials are relatively hard and can only be cut with slow speed, so they must be equipped with an air compressor. 0.45 use 63.5 lenses, the speed is generally 0.2 meters to 0.4 meters per minute, 0.7 with 50 lenses, the lines for 0.3mm or so, cut two times, the speed is generally 0.3 to 0.5.
