Laser cutting machine is widely used in metallic and nonmetallic material processing, greatly reduced the processing time, reduced processing cost and improved the quality. With the traditional method than the material processing, laser cutting its high cutting quality (incision narrow width, heat affected zone small incision, bright and clean), high cutting speed, high flexible (optional cut any shape), and extensive adaptability of materials, etc.

 Laser beam can be focused into very small points of light to its smallest diameter can be less than 0.1 mm, make focus place reach high power density can be more than 106 W/cm2. Then beam input (by light conversion) is far more than the quantity of heat of reflection, transmission or diffusion material part, and material quickly heated to a humidity vaporization, evaporation form hole. Along with the beam and material relative linear movement, make the hole is so narrow width continuous form (such as 0.1 mm or so) cut seam. Trimming hot effect is small, basic no distortion.

 During the cutting also add and cut materials for auxiliary gas phase. Steel cutting as the assistant to the gas and oxygen dissolved melt metal produce exothermic chemical reaction oxide materials, laser marking processing also help blow in the cut seam slag. Cutting polypropylene plastic use compressed air, flammable materials such as cotton, paper cutting use inert gases. Enter the nozzle of the auxiliary gas can still cooling lens, prevent dust into the lens in the lens and led to a pollution lens overheating.

 Most of the organic and inorganic can use laser cutting. In the industrial manufacture occupies component heavy metal processing industry, many metal materials, no matter it is what kind of hardness, can be into shape without distortion cutting (currently use the most advanced laser cutting system can be cut in the thickness of the steel industry already be close to 20 mm). Of course, to high reflectivity materials, such as gold, silver, copper and aluminum alloy, they are also good heat transfer conductor, therefore laser cutting is difficult, can't even cutting (some difficult to cut materials can use pulse wave laser cutting, the extremely pulse wave value power, can make the material of light absorption coefficient instant soared).

 Laser cutting without burr, ruffled, high precision, is better than plasma cutting. For many mechanical and electrical manufacturing industry as a whole, because the microcomputer program modern laser cutting system can cut convenient different size and shape of the work piece (work piece drawings can be modified also), it often than cutting and molding process more be preferred choose;Although it processing speed slow to die down, but it did not die consumption, need not repair mold, also save mould replacement time, which save processing cost, reduce the production cost, so generally speaking in the economy on a more economical.
