Reviewing the development of construction machinery in the past 10 years, we can see that the construction machinery industry is developing in the direction of information, intelligence, integration and so on. As one of the barometers of national economic development, the sales data of construction machinery industry are rising, and the number of updates is also rising year by year. Let's take a look at the application of laser cutting machine in mechanical industry. 

While the number of updates is increasing year by year, the support of another partner, laser cutting machine, can not be ignored in the past 10 years. Laser cutting machine began to be widely used in construction machinery industry 10 years ago, mainly used in concrete, crane, road machine, loader, port machinery, excavator, fire fighting machinery, sanitation machinery and other products.

In recent years, many plate laser cutting machine, pipe laser cutting machine used in a wide range of industries. Take bulldozer as an example: organic cover, floor wing plate, bottom guard plate, platform frame, main frame, cab, bucket, moving arm, bucket rod, etc., all need laser cutting machine to process. As for why we chose to use laser cutting machine, because laser cutting in the machining process is contactless machining, there will be no machine pressure deformation, and the processing speed is fast, the precision is high, the application is extensive, and the flexibility is also strong.

Advantages of laser cutting machine

　The main advantages of laser cutting machine are fast, smooth and smooth, and generally do not need subsequent machining. The cutting heat affected zone is small, the plate deformation is small, the slit is narrow. There is no mechanical stress and no shear burr in the incision. High machining accuracy, good repeatability, no damage to material surface. It can process arbitrary plan, can cut the whole board with large format, do not need to open mold, economical and time-saving, and so on.

　　With the development of the research and the integration of the "Internet +", the "Big Data" and other elements, the laser cutting machine will continuously develop the high-precision and high-intelligent direction, solve many problems in the engineering mechanical processing, and also apply more widely in the engineering machinery industry

　　Application of Laser cutting Machine in slender workpiece. Because of the concentrated heat produced by the laser cutting machine, the thermal shadow response area of the workpiece is small. The thermal deformation of the workpiece can be effectively controlled by using the laser cutting machine in the construction machinery industry, especially for the slender workpiece which requires straightness. When the length of the work piece reaches above 5500 mm, the straightness of the workpiece can be effectively controlled by the "microconnection" function of the cutting machine itself. 

　　Application of Laser cutting Machine in Plate parts with more holes. In the construction machinery industry, when the laser cutting round hole is faced with a specific plate thickness, as long as the diameter size of the workpiece round hole is required to be greater than or equal to the corresponding minimum diameter value, and the roughness and diameter size requirements can be used to directly drop the material within the guaranteed capacity of the cutting machine, which saves the drilling process and improves the labor production efficiency. For some workpieces with more holes, the position of holes is determined by using the punching function of laser, which saves the time of positioning holes and the cost of drilling formwork, which not only improves the production efficiency, but also improves the accuracy of the products.
