In fact, there are a lot of skills to use a laser cutting machine. If you do not use it in the normal way during the application process, it is basically difficult to guarantee its stable operation. If you want to get its work efficiency If you want to improve, you need to apply a lot of skills in the process of use, as follows:



The kerf width of the arc cutting of the laser cutting machine is 1.5~2 times wider than that of the oxygen-acetylene cutting. As the plate thickness increases, the kerf width also increases. For stainless steel or aluminum with a plate thickness of 25mm or less, low-current plasma arc cutting can be used. The flatness of the incision is very high. Especially for the plate with a thickness of 8mm or less, small edges and corners can be cut, even without processing. Weld directly, which is difficult to obtain with high current plasma arc cutting. This provides convenience for cutting irregular curves and cutting irregular holes in thin plates.



The flatness of the cutting surface refers to the distance between the highest point and the lowest point on the cutting surface of the measured part, and the distance between two parallel lines in the direction of the inclination of the cutting surface. When the CNC cutting machine uses high-energy ion arc cutting, in order to ensure the consistency of its cut width, it is necessary to comprehensively analyze and consider various parameters. This involves the material of the cutting material, the content ratio of various metals, and the grasp of the height of the cutting torch during the cutting process. Under normal circumstances, there is a molten layer about 0.25~3.80mm thick on the surface of the plasma arc incision, but the chemical composition of the incision surface has not changed.



Laser cutting machine uses the plasma arc to penetrate the material surface to achieve the cutting effect. The plasma arc often cuts more metal from the upper part of the incision and the lower part, so that the end face of the incision is slightly inclined. The upper edge is generally square, but sometimes slightly rounded. shape. It may result in the distance between the two cutting surfaces on the upper edge of the incision caused by the cutting beam. When the upper edge of the incision is melted, the distance between the two cutting surfaces immediately below the melted layer is abnormal.



For example, when cutting aluminum alloy containing Mg5%, although there is a 0.25mm thick molten layer, the composition has not changed and no oxides appear. If the cut surface is used for welding directly, a dense weld can also be obtained. When cutting stainless steel, because the heated zone quickly passes the critical temperature of 649°C, chromium carbide will not precipitate along the grain boundaries. Therefore, cutting stainless steel with plasma arc will not affect its corrosion resistance.



According to the above method, the laser cutting machine can be used well. Generally, there is no need to worry about the unevenness of the processed surface afterwards.

Users who have used a laser cutting machine should know that its cutting effect is very good, and it can automatically deburr after cutting, so you don't have to worry about its processing surface is very rough. But generally, if you want to get a good cutting effect, you need to take some measures to ensure it.



Each drawing of mechanical parts used for machining has technical requirements for deburring. In the deburring process, technologists are often unable to compile process documents. They usually use files, cloth wheels, emery cloth, belts, etc. to remove burrs. With the progress of science and technology and the development of production, manual deburring can no longer meet the requirements of product quality and production methods in the modern market. Laser cutting machine finishing technology has gradually replaced the traditional deburring process, and more and more People pay attention to it. At present, the finishing and finishing of mechanical parts in some advanced enterprises have been incorporated into the technical requirements of the drawings by technicians, and a standard process has been formed.



Laser cutting machine processing, in terms of process, is only the primary processing step of the material. For most mechanical processing, the flatness and smoothness of the cutting parts can meet the requirements of secondary processing. Of course, for some sheet metal For fine processing such as metal processing, there are still some gaps in the accuracy of CNC cutting. With the rapid development of laser cutting machine application technology in recent years, the surface finish of the cutting material has also been significantly improved. The following will mainly focus on this aspect. User communication.







The laser cutting machine processing technology has been widely used in the finishing of auto parts: intake and exhaust pipes, intake valves, booster chambers, fuel injectors, fuel injection nozzles, cylinder heads, turbine housings and blades, Splines, gears, brakes, etc. For example, rough cylinder head castings can be produced on a special two-station abrasive flow production line, and the output can reach 30 pieces per hour. The roughness can reach Ra0.4μm from Ra4μm or Ra5μm, which can reduce exhaust gas emissions by 7%. Power increased by 6% and mileage increased by 5%.



The recently developed micro-hole abrasive particle flow technology for laser cutting machines is unique in processing fuel injection nozzles. According to the relationship between extrusion pressure, abrasive temperature and viscosity, it performs complex program calculations. In the process of processing, when the set flow rate of the fuel injection nozzle is reached, the processing will stop automatically. The processing time is about 10 seconds, and the flow dispersion can be controlled within ±1%. The flow tester and high-pressure cleaning equipment are matched with this processing equipment. These equipments can be provided with single station or multiple stations according to user needs. It can also be a complete system with manipulator connection, including processing, measurement, and cleaning.



The above is the relevant knowledge of the use of laser cutting machine, I wonder if you have any unclear points after reading this content?
