Stainless steel laser cutting machine cutting material is what? In the use of stainless steel laser cutting machine, workers will always encounter such and such problems, which encounter the most is to cut the material, so that workers are very anxious. In general, this kind of problem is the pressure of the laser cutting machine is not adjusted, the following xiaobian will take you to know about the stainless steel laser cutting machine! Laser cutting machine in the laser cutting process, the pressure of the auxiliary gas has a great influence on the cutting results. The auxiliary gas must have enough pressure to completely remove the cutting waste. Generally, when cutting a thicker workpiece, the pressure should be reduced a little. The residue stuck to the workpiece will destroy the cutting edge. Increasing the gas pressure can advance the cutting speed, but after reaching a maximum, increasing the gas pressure will cause the cutting speed to decrease. Under high auxiliary gas pressure, the cutting speed of laser cutting machine is reduced not only because of the high airflow velocity and the enhancement of cooling effect of hanging zone, but also because of the interference of intermittent shock wave in airflow to cooling of laser zone. The inhomogeneous pressure and temperature in the flow will cause the change of the density of the flow field. Such a density gradient results in a change in refractive index of the field, thus drying the focus of the beam energy, resulting in refocusing or beam divergence. This interference can affect the melting efficiency and may sometimes change the mode structure, resulting in a reduction in cutting quality if the beam diverges too much. The light spot is too large, and even can not effectively cut the serious consequences. When we use fiber laser cutting machine cutting, want to cut the product and to the most accurate, then we must first understand what will affect the accuracy of cutting, we will give you a brief introduction: < BR /> The laser beam is conical, so the slit cut out is conical, in this case, the thickness of 0.4mm stainless steel will be much smaller than 3MM slit. Therefore, the shape of laser beam depends on one of the factors that affect the cutting accuracy of metal laser cutting machine. In this conical laser beam conditions, the greater the thickness of the workpiece, the lower the accuracy will be, so the greater the slit. The precision of the table, if the table precision uneven or other reasons will also lead to high precision laser cutting effect. When the conical laser beam is gathered together, it will become smaller and smaller, so the precision of the laser cutting is becoming higher and higher, especially the width of the slit is becoming smaller and smaller. At this time the smallest spot can reach 0.01mm. This is also one of the factors that affect the cutting accuracy of laser cutting machine. In this case, the cutting precision of different materials is slightly different. Even if it is the same material, if the composition of the material is different, the precision of cutting will be different. Therefore, the workpiece material also has a certain impact on the laser cutting accuracy. The above is the stainless steel laser cutting machine to cut the material, in the use of stainless steel laser cutting machine to cut things, we must master the pressure, pressure is too large, too small are prone to cutting problems.
