Laser cutting machine cutting speed and cutting seam width of the inverse relationship

by：Transon 2020-10-28

Processing, laser cutting machine cutting speed has a considerable effect on the quality of the cutting material, the ideal cutting speed will make the cut surface presents more smooth lines, and the lower part of material will not appear slag. When auxiliary gas pressure and laser power, cutting speed and cutting seam width presents a nonlinear inverse relationship, when cutting speed is slow, the laser energy in the role of the kerf width prolonged, leading to the kerf width increases, when the speed is too slow, laser beam effect time is too long, the artifacts on kerf width and incised seam will be a big difference, the quality of the cutting down, production efficiency will be greatly reduced. With the increase of cutting speed, the effect of laser energy on the work piece shorter time, thus making smaller thermal diffusion and heat conduction effect, thereby cutting seam width correspondingly smaller. When the speed is too fast, by cutting the workpiece material is caused by a lack of cutting heat input can't cut through case, this kind of phenomenon belongs to incomplete cutting, and the molten material is not blown off in time, the molten material will make cutting seam welding again.
