Metal laser cutting starts by scanning the data surface with a high power density laser beam, heating the data to thousands to tens of degrees Celsius in a very short time, melting or vaporizing the data, and then melting or vaporizing the material with high pressure gas. Blow away from the slit and reach the intent to cut the data. The laser is cut, so the traditional mechanical knife is replaced by the invisible beam. The mechanical part of the laser head and the operation have no touch, and the work surface will not be scratched during the operation; the laser cutting speed is fast, and the lubrication is flat. Usually no subsequent processing is needed; the heat affected zone is small, the plate deformation is small, the slit is narrow (0.1mm~0.3mm); the cutting has no mechanical stress, no shear burr; the processing precision is high, the repeatability is good, and the data appearance is not damaged; CNC programming, which can process the floor plan, can cut the whole board with a large format, without opening the mold, saving economy and time.
　 Several advantages of metal laser cutting:
1. Active identification: The program actively recognizes the application of the system. For all kinds of colored graphics on the metal sheet, the active edge-cutting can be completed according to the requirements.
2, intelligent typesetting: can be arranged in a different scale of the appropriate pattern, the data utilization rate to the extreme, can also provide active edge cutting function, saving energy, forward power. In addition, it can also use the copy board system to re-type the remaining materials of the corners, saving data costs, saving labor and materials.
3, fine cutting: can be cut once, accurate, no burr. The metal pipe can also be finely punched, slotted, cut, and the like. It can also be cut through the intelligent positioning of the follow-up focusing system to cut different thickness data and shaped plates. Especially when the data is uneven or the corners are lifted, the manual cutting can be completed without manual focusing.
4, rapid copy board: After the CCD identification system, the software can actively complete the general identification of multiple metal objects, and generate the files used by the computer, and then complete the active typesetting and cutting of the required graphics and objects, convenient and fast, and save Lost all the plate making links.
Generally speaking, it is recommended to use carbon steel plates within 20mm, stainless steel plates within 10mm, and non-metal materials such as acrylic and wood boards. Laser cutting start without cutting force, no deformation in processing: no tool wear, good data adaptability: whether it is simple or messy parts, it can be cut with a laser at a fine speed: its slit is narrow and the cutting quality is good. High degree of initiative, simple operation, low labor intensity, no pollution: can complete the active layout, nesting, advancement of data utilization rate, low production cost and good economic returns.
There are many factors to be considered in laser cutting and selecting. In addition to thinking about the maximum scale of the current workpiece, the raw material, the maximum thickness of the demand cut, and the size of the original data, more needs are considered in the future development direction. The size of the largest workpiece to be processed after the modification of the skill of the product, and the format of the supply information of the steel business site are aimed at the most material of the product, the loading and unloading time, and the like.
Laser cutting and starting is a technological revolution of sheet metal processing, and it is the “machining center†in sheet metal processing; laser cutting has high degree of flexibility, high cutting speed, high production power, short product production cycle, and wins for customers. A wide range of shopping malls, the useful life of this skill is long, most of the foreign countries beyond the thickness of 2 mm plate selection laser cutting, many foreign experts believe that the next 30-40 years is the golden period of laser processing skills development.
　　 Metal laser cutting machine application scale summary
Laser cutting and booting are used in various occupations such as light industry and heavy industry. Currently, there are traditional cutting start, plasma cutting start, flame cutting start, and laser cutting start. In the metal cutting and booting, there are currently traditional cutting tools for cutting and laser cutting. The single adoption of laser cutting and starting is mainly metal sheet metal processing, metal cutting, metal cutting, casing, chassis cutting processing, sanitary ware, kitchen utensils, instrument panel, elevator panel and so on.
At present, laser cutting is divided into medium and small power and high power cutting. The small and medium power cut start alone is below 1000W, and the price is sure to be sold. The thickness of the cut metal will not exceed 10 thick. The high-power laser cutting starts at 1000W or even several kilowatts. The thickness of the cut is thick, and the cost is relatively high. As long as the processing of a large manufacturer such as an automobile part is applicable.
A single medium and small power metal cutting can be cut:
1. Cut the carbon steel plate. The modern laser cutting system can cut the maximum thickness of the carbon steel plate to nearly 20mm, and the slit of the thin plate can be narrowed to about 0.1mm. The laser-cut low-carbon steel has a very small heat-affected zone and is smooth, smooth and straight. For high carbon steel, the quality of laser cutting and trimming is better than that of low carbon steel, but its heat affected zone is larger. Wuhan Jiaming laser metal series laser machine has a maximum cutting depth of 10mm.
2, stainless steel cut. Laser cutting makes it easier to cut stainless steel sheets. High-power YAG laser cutting system cuts the maximum thickness of stainless steel up to 4mm. We developed a low-power YAG laser cutting system to cut stainless steel up to 4mm thick.
3. The alloy steel plate is cut. Most alloy steels can be cut with a laser and the quality of the trimming is excellent. However, tool steels and hot-mould steels with high tungsten content will have corrosion and slag when laser cutting.
4. Cut aluminum and alloy sheets. The aluminum cut is attributed to the ablation cut, and the auxiliary gas is blown away to melt the melt in the cut zone, so that a good cut surface quality can be obtained. The maximum thickness of the currently cut aluminum sheet is 1.5 mm.
5, other metal materials cut. Copper is not suitable for laser cutting, cutting is very thin. Most of titanium and titanium alloys and nickel alloys can be cut by laser. Non-metallic materials. Wuhan Jiaming laser CO2 laser cutting start CO2 marking engraving machine series can be used to cut wood, paper, rubber, leather, acrylic, plastic, fabric fiber composite materials, carved horns, two-color plates, lacquered copper plates. The minimum slit is 0.1mm, and the single metal cutting starter is to add gas when cutting over 4 thick. At present, the metal cutting of Wuhan Jiaming laser can reach 8 thick by adopting the thickness of air cutting. Carbon steel cut thickness is about 8mm, less slag, the thickest can reach 10mm cut, in YAG, the small power professional industry cuts the thickest. Cut stainless steel within 6mm, carbon steel within 8mm can use air cutting to save useful cost, laser cutting and cutting results are also very good.
