The Principle Of Laser Metal Cutting Machine

The beam input (converted by light) is far more heat than the material is reflected, conducted or diffused, the material is quickly heated to the vaporization temperature, and the pores are formed by evaporation. As the beam and the material relative to the linear movement, so that the formation of the hole is very narrow (such as 0.1mm or so) of the slit. Trimming heat effect is very small, basically no workpiece deformation. An auxiliary gas suitable for the material to be cut is also added during the cutting process. Steel is cut with oxygen as the auxiliary gas and molten metal to produce exothermic chemical reaction oxidation material, while helping to blow the slag within the slag. Cutting polypropylene A class of plastic using compressed air, cotton, paper and other flammable materials cut using inert gas. The auxiliary gas entering the nozzle also cools the focusing lens to prevent dust from entering the lens holder and contaminate the lens and cause the lens to overheat.
