Fiber laser cutter cutting stainless steel

    Laser cutting is to focus the laser into a high-power density laser beam through an optical path system. The laser beam irradiates the surface of the workpiece to make the workpiece reach the melting or boiling point. At the same time, the high-pressure gas coaxially with the laser beam will melt or vaporize the metal. As an indispensable processing method in the modern industrial manufacturing field, laser cutting not only has the characteristics of fast and efficient, but also has a good processing effect. With the relative position of the beam and the movement of the workpiece, the material finally forms a cutting weld, so as to achieve the purpose of cutting.
    At present, the maximum cutting capacity of laser cutting in industrial applications is: carbon steel is 36 mm, steel plate quality is good, and the speed can reach 650 mm/min. If the 36 mm steel plate material is good, the machine is good, the graphics are not complicated, and the cutting quality is still good. In general, the size of the blast hole is related to the plate thickness, and the average diameter of the blast hole is half of the plate thickness. Therefore, the hole diameter of the thick plate blasting hole is relatively large and not round, which is not suitable for parts with high machining accuracy requirements, and can only be used for scrap.
    Stainless steel is 25 mm. When high-pressure nitrogen is used as an auxiliary gas, the speed is relatively slow, about 400 mm/min. However, domestic users generally aim for laser cutting, with low carbon steel below 25 mm and stainless steel below 16 mm. The choice of the laser head nozzle does not match the thickness of the processing board. The laser cutting line speed is too fast. Operation control is required to reduce the line speed. Nozzle induction is not allowed to cause the laser focus position error to be too large. It is necessary to recheck the nozzle sensing data, especially for cutting When aluminum.
    Laser cutting uses an invisible beam instead of a traditional mechanical knife. The mechanical part of the laser cutter head has no contact with the workpiece, and the working surface will not be scratched during the working process. The laser cutting speed is fast, the cut is flat and smooth, and generally does not require subsequent processing. The area affected by the cutting heat is small, the plate deformation is small, and the cutting gap is narrow (0.1mm~0.3mm).
    Generally speaking, 1000 W fiber laser cutter can cut about 10mm carbon steel plate, while stainless steel plate is a bit difficult to cut. In order to increase the cutting thickness, edge effect and speed must be sacrificed. For different metal materials, the cutting thickness of different power metal laser cutters has a great relationship with the cutting material.
    Laser cutting mirror stainless steel, in order to prevent serious burns of steel plate, it is necessary to insert laser film! Although it is protected by film, there will still be slight burns on the edges. At this time, the laser cutting process parameters must be strictly controlled during the processing to maintain the good corrosion resistance of this material.
    Laser cutting has involved all walks of life. Due to the needs of enterprises, some customers may need to cut carbon steel materials by about 8 mm. 8mm thick carbon steel materials can no longer meet the speed requirements of traditional fiber laser cutting machines, and there is a certain gap between the quality of laser cutters. If metal materials below 6mm are used for long-term cutting, use a 500 W fiber laser cutting machine with moderate power, relatively cheap price and fast economic benefits.
    For this thick material, many customers still choose flame cutting or CNC punching, but the processed product has many burrs and slow speed.
    Laser cutter has become a necessary equipment for sheet metal cutting due to its strong cutting ability, fast speed and high processing accuracy. In addition, the fiber laser cutting machine can also cut various complex graphics as required to meet the needs of various industries.

    Which machine is used to cut stainless steel plates? It has the characteristics of beautiful surface, corrosion resistance, high temperature resistance, high strength, easy forming, and excellent welding performance. It is widely used in sheet metal industry. At the same time, the finished product has the characteristics of no surface coating, environmental protection, cleanliness, and low maintenance cost, making it the first choice for the high-end sheet metal industry.
    Feature metal laser cutter:
    The utility model has the characteristics of good quality, small deformation, smooth appearance and beautiful appearance. Fast cutting speed, high efficiency, low cost, safe operation and stable performance.
    Imported servo motor and oriented drive mechanism are adopted, and the cutting precision is high. With professional software, you can design all kinds of graphics or text for real-time processing, which is flexible and easy to operate.
    The laser beam can be easily divided into time and space, and can be processed simultaneously or sequentially.
    Stainless steel sheet laser cutter has a wide range of applications, whether it is metal or non-metal, it can be used for cutting. Under normal circumstances, the carbon dioxide laser cutter can be used to cut non-metallic materials such as cloth and leather; the fiber laser cutter can be used to cut metal materials, and the plate deformation is small.
    Laser cutting makes it easier to cut stainless steel plates. For stainless steel cutting, different processing gases can be selected according to needs. If you choose oxygen, then in a high-temperature cutting environment, the oxygen is easily oxidized, resulting in a slightly uneven cut. However, if nitrogen is used as the processing gas, since nitrogen is not easily oxidized at high temperatures, the blade is very smooth. Of course, if you encounter a very thick steel plate, by coating the surface of the steel plate with an oil film, the perforation effect will be better, and the processing quality will not be impaired.
    Suitable for cutting thin metal materials such as aluminum alloy plate, stainless steel plate, galvanized plate, titanium alloy plate, carbon steel plate, cold rolled plate, brass (purple) copper, etc.
    In the field of sheet metal cutting, the metal laser cutter has a huge market advantage in the field of sheet metal cutting, and it is undoubtedly the best cutting tool. When processing metal sheets within 12 mm, many metal processors choose medium and low-power fiber laser cutters. The processed product has a smooth surface without burrs, and the cutting speed and quality are unmatched by other equipment.
    The laser cutter is not only fast in cutting speed, good in cutting effect, but also very low in cutting cost, which also makes more and more users willing to use laser cutters for processing.
    Stainless steel laser cutting has realized the comprehensive and rapid development of China's economy in the era of steel demand, creating a golden opportunity for the manufacturing industry, especially in recent years, the manufacturing industry's demand for stainless steel products has been increasing.
    Stainless steel products are mainly thin plates, such as doors and windows, kitchen utensils, accessories, etc., used for thin stainless steel products, generally less than 5mm, so laser cutting 5mm stainless steel plates is the best choice.
    The cost of stainless steel laser cutting is higher than that of wire cutting, and the accuracy is not as good as wire cutting, but the speed is twice that of wire cutting. Mass production can be realized. After cutting, non-metallic materials can be processed to realize intelligent processing. One machine replaces multiple stages and becomes processing. The core of the device. It can be seen that laser cutting stainless steel is a fast and effective processing method, but the control of cutting quality is particularly important.
