How to ensure the quality of products, reduce labor intensity, labor costs, and improve the labor environment are the needs of modern production. For example, the boiler products of a company are mainly made of sheet parts, which are different in material and shape. For example, in actual production, the wear plate on the waste heat furnace adopts the form of densely distributed small holes on the stainless steel sheet, and its small holes can only be formed by the use of a metalworking drill. The wear plate of a boiler consumes a box and a half of drill bits, which takes two and a half months to complete. However, the manufacturing cost of the new laser cutting is low because it does not require the consumption of tools and molds. Therefore, it has great advantages not only in the production of small batches of parts with special shapes, but also in batch blanking.
Compared with other thermal cutting methods, laser cutting machines are generally characterized by fast cutting speed and good quality, which can be summarized as follows:
1) Fast cutting speed
Use a 1000W laser cutting machine to cut 2mm thick low carbon steel plate, the cutting speed can reach 6 m/min, and the material does not need to be clamped during laser cutting, which can not only save the fixture, but also save the time of loading and unloading.
2) Good cutting quality
Because the laser spot is small, the energy density is high, and the cutting speed is fast, the laser cutting can obtain better cutting quality. The dimensional accuracy of cutting parts and components can reach ± 0.05mm, and the cutting surface is smooth and beautiful, and the surface roughness is only tens of microns. Even laser cutting can be used as a process without mechanical processing. The parts and components can be directly used. After laser cutting, the width of the heat affected zone is very small, and the performance of the material near the cutting seam is almost unaffected. Besides, the workpiece deformation is small, the cutting accuracy is high, and the geometric shape of the cutting seam is good, The cross section of the slit presents a regular rectangle.
3) High cutting efficiency
The laser cutting machine can generally be equipped with multiple CNC worktables, and the whole cutting process can be fully realized by computer numerical control. The operation is that the NC program can be changed to cut parts of different shapes.
4) Environmental protection
To process parts of different shapes, it is not necessary to change the “tool”, but only to change the output parameters of the laser. The laser cutting process has low noise and low vibration.
5) Compared with the traditional cutting method, laser cutting machine can save materials, improve production efficiency and reduce costs through reasonable nesting and cutting heat effect.
