The narrow kerf width of laser cutting machine, and the cause of the deformation

Also add in the process of laser cutting machine for cutting and cut material suitable auxiliary gas. Steel cutting when using oxygen as auxiliary gas exothermic chemical reactions and molten metal oxide materials, at the same time help to blow away the slag in the slot. Cutting polypropylene plastic using compressed air, flammable materials such as cotton, paper cutting using inert gas. Auxiliary gas entering the nozzle cooling focusing lens, can prevent dust from entering the lens holder in pollution lens and cause the lens to overheat. Most organic and inorganic materials can use laser cutting machine. In the industrial manufacturing systems possess weight heavy metal processing industry, many metal materials, whether it is what kind of hardness, there can be no deformation of cutting. And, of course, the high reflectivity material, such as gold, silver, copper and aluminum alloy, they are also a good heat conductor, laser cutting is very difficult, therefore, can't even cut. On the other hand, how to adapt the mold design of workpiece size and shape change perspective, laser cutting machine processing can also be giving full play to the advantages of its precision and good repeatability. As a means of cascading priority die & mould manufacturing, because do not need advanced mould production workers, laser cutting operation cost is not high also, so also can significantly lower mould manufacturing cost. Laser cutting die also bring additional benefit is that die trimming produces a shallow hardening layer ( Heat affected zone) To improve the running wear resistance of the die. Out of contact characteristics of laser cutting brings to the circular saw blade for cutting forming stress free edge, due to increases the service life of saw blade. Focused laser beam into a small spot, causes the focus to achieve high power density. Then input heat than light beam were part of material reflection, transmission, or spread, degree of material quickly heated to boil, evaporation form holes. Along with the relative linear beam and mobile, make continuous forming holes cutting seam width is very narrow. Trimming heat effect is very small, almost no distortion.
