The difficulties of laser cutting machine for cutting thick plate
1. Kerf width is too narrow, the increase of heat loss. Lower cutting speed increase cutting area of the heat loss. Heat loss is the main form of heat conduction, the greater the thickness, the greater the heat conduction losses, the lower the cutting speed also. Incision at the bottom of the material removal becomes inconsistent, although laser penetrates the thick plate, a large amount of slag bonding at the bottom. Hang slag formation is caused by low average incision at the bottom of the cutting temperature, the temperature is low because of big energy loss, this kind of circumstance of the incision quality usually is not high.
2. Optical fiber laser spot diameter smaller, focal depth is limited. Optical fiber laser cutting metal medium thickness plate, although the ability to maintain cutting depth with higher laser power density, but because of the beam diameter smaller, kerf width is fine, is not conducive to cutting slag discharge. This model of optical fiber laser and light beam collimation plastic range and puts forward the higher request, also for thick plate in the optical fiber laser cutting metal craft quality brings great difficulty.
3. The role and influence of auxiliary gas quality and pressure. In the case of oxygen; In the optical fiber laser cutting carbon steel thick plate oxygen up if it is important. Laser incident to the workpiece surface holes, when the laser beam moving in the direction of the cutting holes and surrounded by oxide melt kerf width. The purity of oxygen and pressure has great influence on laser cutting, with impurity, inappropriate pressure oxygen cannot provide enough energy to the melting of the incision at the bottom of the form of high liquidity, and thus reduce the cutting quality and cutting speed. By measuring the mass of the gas cutting seam location aided and pressure, and found that the more narrow kerf width, auxiliary gas effect is poorer, cutting quality of the more difficult it is to maintain, thus ensure the quality of suitable cutting seam width, auxiliary gas and air pressure control, to the effect of cutting quality is very heavy.
4. The geometry of the difference makes the cutting quality of the inflection point decline. Laser cutting plate, the melt front Angle becomes highlighted, which will lead to a drop in material on the laser absorption coefficient, and by increasing the cutting power, lower cutting speed to ensure the cutting quality.
