Application advantages of laser cutting machine in stainless steel cutting

With the continuous development and progress of industrial manufacturing, the application of stainless steel has been very extensive. It is used in household products, electronic appliances, vehicles, building materials, industrial machinery and other fields. Stainless steel is composed of steel with a carbon content of less than 1.2% and chromium with a content of more than 10.5%. It is also famous for its low rust resistance and high corrosion resistance.



At present, the processing of stainless steel is mainly based on laser cutting. The laser cutting technology uses a fiber laser beam to act on the surface of the material on a small scale. The high-density and high-energy laser beam heats the stainless steel plate locally and evaporates the area, thereby realizing the cutting of stainless steel. .

There are many focusing methods for stainless steel laser processing. The commonly used methods are direct focusing with focusing mirror and galvanometer plus flat field mirror. The combination of galvanometer and flat field mirror is widely used for its advantages of fast processing speed and wide application range. This focusing method has no requirements on the laser light source, and can carry lasers of various wavelengths and pulse widths. The types of processing materials are mainly thin plates, such as stainless steel plates, carbon steel plates, aluminum alloys and composite metal plates.



For some manufacturers that use stainless steel as the main component, laser cutting stainless steel is currently a relatively fast and efficient processing method. The good corrosion resistance of such materials can be maintained if the parameters are strictly required during processing. The most important process parameters that affect the quality of stainless steel cutting are cutting speed, cutting accuracy, laser power, air pressure, etc.


But laser cutting machines also have some drawbacks when cutting stainless steel:

1. Under the condition that various process parameters are set to ensure good linear cutting effect, excessive ablation will occur when cutting corners, which will reduce the quality of the corners; especially for small-angle acute-angle cutting, due to overlapping cutting paths, the laser energy will be reduced. Concentration leads to excessive ablation at the corners; in order to ensure the overall cutting quality, different parameters must be set for cutting at different positions, and the parameter modification is relatively cumbersome.

2. When various process parameters are set to ensure a good cutting effect, the phenomenon that the cutting is not penetrated at the beginning of the cutting often occurs, and the surrounding plates are overheated and deformed.
Stainless steel is one of the most common metals in industrial manufacturing. Baiwei Laser G series fiber laser cutting machine can adapt to the cutting of various stainless steel plates. It has good cutting quality, is not easy to cut through, the plate dissipates evenly, is not easy to burn, saves the use of protective gas, effectively reduces cutting costs, is safe and reliable, has low failure rate, high cutting effect, and good precision. The advantages.
