We know that there are many kinds of metal materials that need to be processed in production activities, which have a great relationship with market demand. However, because the materials are different, in order to make the cutting effect satisfactory, it is necessary to add different auxiliary gases to assist the processing when processing different materials.  The laser beam of the metal laser cutting machine is focused into a small spot with its smallest diameter, which enables a high power density at the focal point. At this time, the heat input by the light beam far exceeds the part that is reflected, conducted or diffused by the material, and the material is quickly heated to the vaporization temperature and evaporates to form a hole. As the beam and the material move relatively linearly, the holes continuously form slits with a very narrow width. The heat effect of trimming is very small, and there is basically no deformation of the workpiece.  In the process of metal laser cutting machine, auxiliary gas suitable for the material to be cut is added. When steel is cut, oxygen must be used as an auxiliary gas to produce an exothermic chemical reaction with the molten metal to oxidize the material, and at the same time help blow away the slag in the slit. Compressed air is used to cut polypropylene and other plastics, and inert gas is used to cut flammable materials such as paper. The cotton and the auxiliary gas entering the nozzle can also cool the focusing lens, preventing smoke and dust from entering the lens holder to contaminate the lens and cause the lens to overheat. Most organic and inorganic materials can be laser cut. In the metal processing industry, which accounts for a heavy share of industrial manufacturing, many metal materials, no matter what hardness it has, can be cut without deformation (the most advanced metal laser cutting machine can cut the thickness of industrial steel. Close to 20mm). Of course, for high-reflectivity materials, such as gold, silver, copper and aluminum alloys, they are also good heat transfer conductors, so metal laser cutting machines are difficult or even impossible to cut (some difficult-to-cut materials can be cut with pulsed laser beams) , Due to the extremely high peak power of the pulse wave, the absorption coefficient of the material to the beam will instantly increase rapidly).   Wuhan Gaoneng Laser Equipment Manufacturing Co., Ltd. is a high-tech enterprise integrating Ru0026D, production and sales of professional laser complete sets of equipment. Not only successfully developed laser equipment with advanced technology, but also used self-support import and export rights to promote products to more than 40 global markets including Hong Kong, South Korea, Vietnam, Malaysia, Thailand, Australia, the United States, Japan, Germany, the Netherlands, Jordan, etc. nation.
