Familiar with in order to grasp the operation of laser engraving machine and process requirements of the processing industry made easy summary. Large-scale carving machine, sculpture size that corresponds to the greater effect will be almost the sculpture. Since large-scale engraving machine beams longer appear more serious resonance (vibration). Hemisection are a more complicated process, industry has always used cloth, mobile phone keys, reflective materials and so on. Floor flatness requirements are very high, generally made laser tube can be adapted to meet the requirements. Concrete engraving speed and light intensity, the material on the different users of different combinations of the parameters are not the same, more or less the situation are:

 

1, carton packaging industry (rubber plate)

The main use of rubber version of carving YM series models are generally selected focus 50mm lens, the use of PLT and BMP format two. main application PLT. Two formats have the advantages of a concrete analysis of specific situations. When the carving of the word high is greater than 10mm or greater than 1.5mm line pattern of strokes, you can way one show 7mm rubber version of the ordinary single-layer as an example, when the surface of wet newspaper with leak jet Cup, to prevent blowing gas had blown up a lot of wet newspaper, so that hook up to make a more delicate line. At this point the general speed :0.5-adjust to 0.8 meters / min, faster, bigger serrated; adjust for light intensity: 20% -50%. With the depth to adjust the different, if you want some more light intensity up to 60% -70%. Double rubber version are: 4mm double-rubber version of light to reach 1.5mm depth, the speed of 0.5 meters in general want to / min, light intensity of 45%, as the case may be. If you carved the words, when a high degree of less than 10mm, when the general use of sculpture, this time to adjust the speed of the general :10-15 m / min; adjust light intensity for the top 18% -28% deep, depth 55% -75% , the gradient between 0.8-1.5, the resolution is generally 500-600dpi, or the smaller the language the more dense, light intensity should be set too low, and the gradient is relatively more in small settings.

2, cloth embroidery industry

The general fabric cutting machine high-speed crash victims CM or TM series, the general choice of focus 50mm lens, single-cutting at the normal speed is 5 m / min, light intensity of 40% the size of air power, cellular, and mixed bottom roughness , light intensity will affect the size of the crash victims of the effect of fabric. The greater light intensity, the greater the heat radiation, light will have gaps. At present, the biggest problem is that cutting hair is yellow, the cloth flat on the floor on cellular, open the exhaust fan, take away the smoke and dust in time to prevent the dust generated by cutting the cloth yellow smoke, open the air compressor to ensure that the inflatable fruit areas, get rid of impurities within slotted volatiles and dust, blowing the use of inert gas (such as nitrogen) better. (1), the general fabric of the cutting (non-woven, polyester, Dacron, silk, satin, twill, etc.) belong to thin fabric material, in order to ensure the effect of incision, we generally selected focus 50mm lens, small spot, cut a small slit. Open the laser machine external equipment (ventilation, inflatable) to fabric formation and adsorption on the cell floor, inflatable first air compressor pump power. Speed: great graphics or graphics part of the external smooth curve can be used with higher speed, to CM machine as an example, generally at 3-10 m / min; small graphics or graphic curve or corner of the internal part of the use of many low-speed, generally at 0.5 - 3 m / min, light intensity: light intensity of the matching principle is the largest high-speed distribution of light intensity, low-Xiao Guang match, and generally adjust the clock for the 30-60 strong; low at 18-35%, light intensity and the size must be bad value, generally around 5-15% in order to achieve a straight line and curve cutting speed of light intensity when the size of the match. (2) a special cutting fabric (white cotton cloth, clean cloth, and plastic components including PC cloth, etc.) Process requirements: white cotton does not require cutting hair yellow, dust-free cloth after cutting did not change color, hair cut is not hard, for The two fabrics, we have to choose focus 50mm lens, preferably imported radio frequency laser, in order to ensure the quality and stability of spot. Open ventilation, hair (cutting open the air compressor when white cotton), the proposed conditional use of nitrogen. Speed :1.5-3 m / min, light intensity :20-30%, because do not want to achieve, and incision yellow hair is not the purpose of hardening, we have to match the speed of light intensity due to cutting, the speed is too fast we must to improve the light intensity, so that large incision because of the high-temperature light intensity and color burned or hardened, light is too slow at times to stay too long incision, we can not obtain the desired results. The current equipment and processes, in order to achieve the perfection of this process must have difficult requests, in particular, thick white cotton face, incision, there will be discoloration, clean cloth will have a slight appearance of hard hair.

(3) double-layer fabric (stickers) cut (top cut down through a layer of no injury or minor injury)

This is the electronics industry processing technology, optical control of laser precision, stability, and match the speed of light have higher requirements, we generally use the domestic glass proofing, basic to achieve the desired effect, but for high-volume processing in terms of recommended RF Laser imports. Open exhaust blowing, fabric will be formed on adsorption at the cellular and cellular to adjust the flatness of bottom four corners. Set the speed of light: in accordance with the specific parameters of the material, the two are able to achieve a better match on the line, generally on a layer of rice at around 1.5-6, light intensity at around 18-35; under a layer of light speed is not specific requirements to ensure a better quality of incision can be opened quickly as possible that another set of light intensity at the time there is also the margin, so that acceleration and deceleration at the time to ensure implementation of the depth of cutting in line. (Some of this material should not inflatable)

(4) Mark the cutting trademark weaving (fabrics, woven marks, trademarks)

Trademark cutting our use of automatic camera is mainly manual and semi-automatic cutting two working mode depends mainly on the accuracy of the testing machine and positioning precision, each texture are some differences mark out, cut the edges of each completely impossible. Requirements for cutting methods used in our fabrics and cutting almost ordinary, but because of Mark texture and hardness of a trademark on the accuracy is much greater than the cloth, at the speed of light intensity and also have a greater difference. Speed and light intensity depending on the specific processing of the case, reference parameters: the speed of 1.2-5 m / min, 20-55% of light intensity.

3, the cutting and engraving acrylic

PMMA has a variety of materials, the difference between imports and domestically produced a lot of imports from a very smooth cut plexiglass, and some made too many impurities will blister. Acrylic generally use low-speed cutting machines, laser power is not because a lot of thin material and relatively high accuracy. The general rate of not more than 3 m / min, such as CMB series, linear guide lines have detailed, or smoothness. At present we have five focusing mirror to the focal length of focusing mirror is divided into (50mm \ 63.5mm \ 75mm \ 100mm), coupled with double-focusing mirror.

According to material thickness and introduction:

Cutting thick materials (10-20mm)

10mm above the general use of perspex 75mm Focus Lens, 25mm more than the use of perspex 100mm Focus Lens, the most able to cut 32mm plexiglass. 10mm plexiglass cutting: cutting speed is generally 0.08-0.12 m / min, 60-70% of light intensity. 60% of light intensity at the most stable time, air-conditioning leakage jet flow cup size, so that a more smooth edge. Since the greater the cutting hair melting objects were assisted to return to high-pressure gas blowing on plexiglass smooth surface does not form. Transfer of small lookout try. Sometimes, customers need to add together with the film or paper cutting, when the wind is not too small, or else they will fire. Cutting plexiglass light intensity at a certain speed and with better, more slowly, is not a better smoothness. 15mm plexiglass over the best use of imported high-power lasers. PMMA leakage jet when carving cups, try not to carve too deeply carved at the bottom of the formation is very difficult to achieve, the more gas carving the edge of the impact of the effect of the General Assembly, to be more precise carving and clear, and should not blow too small, sub - Chris sculpture should be noted that the resolution settings, if the output BMP format, at 600dpi resolution or more generally, when the speed of 8-18 m / min, light intensity of 20% -30%, turn off blowing when cleaning so that the bottom is more smooth.

Cutting thin material (2-10mm)

Plexiglass 5 mm below the focusing mirror using 50mm, cutting speed is generally 0.35-0.8 m / min, light intensity was 45-65% ,5-10mm plexiglass generally focusing mirror 63.5 mm, cutting speed of 0.15-0.3 m / min, light intensity was 50-75%, large-scale engraving machine for engraving more serious when it appeared the resonance (vibration), may also result in large precision engraving machine lower cutting plexiglass so try not to format models more than one meters, people have plexiglass image the process of carving some white powder in order to feel more clearly, if the water want to erase carved end, it is more ambiguous. Look like and what the specific effects of processing.

Glass (or mirror) of the sculpture

For some real glass sculpture, glass, some customers on the effect of carving out, but will taper place of fragmentation, speed and therefore require high light intensity. The general rate of 10 m / min, light intensity at 35%. Generally mirror carved with metal marking machine, at the bottom of a smooth and delicate.

4 wood cutting and engraving

Application of wood carving at the main cutting boards, wood model, wood parquet, hanger sculpture, wooden photo frame and so on. Materials wood splint has, solid wood, medium density fiberboard, the current application of the most cutting boards are. Distinction between general plywood 3mm, 5mm, 7mm, these are all cut, the normal speed of 3mm plywood-like at 1.2 m / min can be pierced, and some solid-core board can be cut 10mm. The specific situation of the Materials. 6mm cutting board when cutting the best use of 63.5mm focusing mirror, the speed at 0.2-0.4 m / min, light intensity was 75-80%, with large air pump or air compressor, the effect better. General model of wood cutting thickness 3 mm below the general speed is 0.5-1.2 m / min. General with parquet veneer cutting double-focusing mirror, demanding customers, as far as possible selection of radio control. Delicate spot because RF tube, cut a small slit. Hanger sculpture - the best choice for carving small when engraving machine. Wood carving based on the size of graphics, effects and requirements set speed. Some customers want more black birds with the option of carving defocus. Air pump the size of the degree of impact on charred.

Hot cutting and drilling template for carving, drilling template hot there is a variety commonly used materials, cutting with: hot paper drilling, engraving by (MDF) or thin acrylic, paper cutting hot drilling generally focus 50mm lens, open blowing and suction wind, will be formed of cardboard honeycomb on the Absorption of cutting process parameters and no special requirements, as part of graphics will not cut too much, speed is generally 0.5-3.5 m / min, light intensity is generally about 18-40 as much as possible to increase insufflation to reduce the incision edge of the situation change. Hot plate engraving speed drill at 10 m / min, light intensity, 35% at 600 dpi resolution and above. Drilling hot depending on the size of the larger drilling hot, hot drilling thickness thick, hot plate carving have to drill deeper

5, leather cutting and engraving

The main application of the leather uppers carvings, handbags, leather gloves, bags and so on. Some of the production process to fight small, hook line or cutting the surface pattern, process requirements: hook-line yellow hair surface, carving out the background materials, cutting edge non-black leather, sculpture may be clear. Materials have synthetic leather, PU leather, PVC artificial leather, wool leather, semi-finished products, fabrics and all kinds of leather and so on. Engraving speed depending on the size of the graphics, line draw relatively small patterns that slow the speed at 0.8 meters / min, the cutting speed patterns at 1.5-3 m / min, light intensity at 75% of the general wearing leather can be cut . Leather cutting a little slower that the rate of 0.4-1.2 m / min, light intensity at 60-75%, leather cutting incision will be black, air cutting, but the incision will be the formation of oxide layer, the dermis, such as requirements that are not black incision and very difficult to achieve the requirements; will be subject to processing, such as rubber can be cut over the edge of black mud of the James will be going. Smell have also cut out, so far, there is no solution. Nitrogen required for the use of cutting consumption of high-pressure nitrogen, slow and costly, but no oxide layer cutting, cutting a little better results. Paper is not the same as expected, the selection of different cutting methods, such as leather marking can play first wet water standard, the effect better. Cutting the surface can add leather textured paper, to prevent the surface of yellow hair; edge black require special treatment.

6, two-color plate engraving and cutting

According to the material to make different color maps, a character image in the same black-and-white color on the board carved out of two completely opposite effect. Sculpture generally focus 50mm lens, the resolution is usually at 350-500dpi, at the general rate of 8-20 m / min, 20-30% of light intensity, air pump the size of impact on the extent of carving charred. Blowing the greater the results will be fuzzy carving, so best not to breath, but also had to put (jet Cup is not blowing in the case of the sculpture will block the gas nozzles. Color cutting board will be dissolved a little edge, the edge will be black, blade the edge of the scratch are to go through processing). Speed of 1 m / min, light intensity 50-60%, sometimes together with the film cutting, after cutting the tear film, the edge of the surface is even more ideal.

7, carving and cutting Lighting

Lighting Materials: basically PVC, has the surface with cloth, but also with paper. The production process there is drilling, carving, cutting and so on flower-shaped, and some need to draw lines defocus, there is also cutting the flower-shaped, depending on the size of graphics, the general cutting speed at 1.5 m / min, light intensity at 45%, large selection of air or air compressor, the edge will not yellow hair. Carving is generally at 15 m / min, 30% light intensity, resolution up to 200dpi at the bottom of the formation.

8, marble carving

The general use of black marble carving material, no noise. After such image processing on carving out a clear image of characters. Sculpture at the speed of 8 m / min, light intensity at 40%, resolution is 600dpi, Net line is 45 lines / inch.

9, paper cutting (paper-cutting, thin-film cell phone keys, cards and so on)

Models generally use the small paper-cut, double-focusing mirror, because relatively thin smoked paper, graphics will be relatively fine, small air pump most suitable control can be better RF. Thin-film cell phone keys are also compare the use of many customers, the general for proofing. Usually small models with 50mm lens focused. At the speed of 0.5-1 m / min, light intensity at 35% less than the size graphics for essentially all customers through the change to revise the implementation plan, put together with the size to cut joints. However, cellular floor flatness requirements is also very high.

10, knife cutting template

Knife knife mold seam is mainly two types of 0.45mm and 0.7mm on sewing knife more stringent requirements, but also basically the same up and down. Materials are MDF and a 6mm of plastic, these materials are relatively hard, can only slow cutting, so must be equipped with air compressor. 0.45 with 63.5 of the lens, the speed is usually 0.2 meters to 0.4 meters per minute, with 50 of the 0.7 lens, to put bold 0.3mm line cut about twice the speed is generally 0.3 to 0.5.
