Laser cutting machine auxiliary gas role
(Click 286 )Laser cutting machine is a high-precision, high-efficiency processing equipment, widely used in sheet metal processing, aerospace, auto parts manufacturing, communication equipment and other manufacturing processing industry, cutting processing materials are mainly metal, plastic and other materials cutting processing. In order to make the workpiece processing effect is good, auxiliary gas is an important link to adjust the cutting process, according to the different material and thickness of the cutting workpiece, combined with the power of the laser cutting machine, choose different cutting process, the use of auxiliary gas requirements are also different.
Common auxiliary gases include oxygen, air, nitrogen, and so on. Compressed air is more readily available than oxygen and nitrogen, the price is very cheap compared to oxygen and nitrogen, and the use of compressed air as an auxiliary gas cutting is very common. The role and characteristics of each auxiliary gas in the laser cutting process are also different.
Why do laser cutters need to rely on auxiliary gas for cutting? ① Because the use of auxiliary gas can blow away the slag of the cutting gap, prevent the surface of the cutting workpiece from hanging slag, to achieve a good cutting effect; The auxiliary gas can effectively cool the workpiece and reduce the heat affected zone; ③ The auxiliary gas can effectively prevent smoke from entering the lens and polluting the lens, protect the lens and extend its service life; The auxiliary gas matched with the cutting material can react with the workpiece, play a combusting effect, and speed up the cutting speed.
Considering material properties and process requirements is also one of the factors that must be taken into account in the selection of auxiliary gases. When laser cutting machine processes different materials, the choice of auxiliary gases has a great impact, such as metal needs to use inert or active protective waste to prevent it from being burnt; Plastic requires the use of inert waste to avoid toxic substances.
