Laser beam is focused to a small spot, bringing the focus to very high power density. This time beam input is much more than material reflection, parts of conduction and diffusion, quickly heated to vaporizing the material level, evaporation formed holes. Move with beams and material is relatively linear, continuous holes forming a narrow width of the kerf. Trim heat is very small, almost no deformation of the workpiece.
During the cutting process also adds secondary vapour is fit with the material to be cut. Steel cutting oxygen as the secondary vapour exothermic chemical reactions with the molten metal oxide materials, while helping to blow away slotted in the slag. Polypropylene a plastic cutting with compressed air, cotton, paper and other combustible material cutting the use of inert gas. Into the auxiliary steam nozzle cooling focusing lens, preventing pollution in the soot into the lens the lens and cause the lens to overheat.
Most organic and inorganic materials can be cut with a laser. In industrial manufacturing systems have very heavy metal processing industry, many metallic materials, regardless of it’s hardness, can be cut without deformation. Of course, highly reflective materials, such as gold, silver, copper and aluminum, which are also good conductors of heat transfer, laser cutting is difficult, or even cut. Laser cutting burrs, wrinkle-free, high precision, superior to plasma cutting. On many electromechanical manufacturing industry for, due to computer program of modern laser cutting system can convenient cutting different shape and size of artifacts, it often than rushed cut, and molded process more was priority selection; despite it processing speed also slow Yu die rushed, but it no mold consumption, without repair mold, also save replaced mold time, to save has processing costs, reduced has production cost, so from General Shang consider is more pays of.
