1, laser cutting machine cut surface is smooth, no stripes, no burr, no 2, cut the size of aperture of brittle fracture, the perpendicularity of the kerf width is good, small heat affected zone 4, there is no material burning, not melt layer to form, no big slag 5, laser cutting machine for cutting the material heat affected 6, incision rough surface plating, surface roughness is key to measure the surface quality of laser cutting the size of the laser cutting machine laser cutting surface roughness is mainly look at the following three aspects: (1) can be adjusted in the process of laser cutting machine for cutting process parameters, such as power size, cutting speed, auxiliary gas type and pressure etc.
(2) the intrinsic parameters of the cutting system, such as speckle pattern, focal length, etc. ;
(3) physical parameters of laser cutting machine processing material, such as the laser absorption, melting point, viscosity coefficient of molten metal oxide, metal oxide surface tension, etc.
