Laser cutting machine is to use the focus of high power density laser beam artifacts, make a place is rapidly melting, evaporation and ablation of materials or reach the ignition point, at the same time and the beam coaxial high-speed airflow blow molten material, thus a thermal cutting method for cutting work pieces. Wavelength of 1070 nm ytterbium doped fiber laser is an ideal light source to laser cutting. What factors influence of laser cutting surface roughness, cutting speed, cutting direction and use for a long time under the condition of different cutting surface roughness consistency and speed consistency? The beam parameter product the BPP is an important index for describing the laser beam quality, BPP value is smaller, on behalf of the beam can be gathered up the smaller, thus the higher power density. yl - The CUT of the fiber core diameter of 50 microns BPP < 2100 microns BPP < 4, good beam quality, the higher cutting speed faster, cutting surface finish, and made it possible to copper aluminum contour reverse material cutting, help customers improve the production efficiency of cutting, the quality and range of application.
