The choice of speed of metal laser cutting machine is very important when cutting materials. If the speed is too slow and the effect is good, it will affect the production. If the speed is high but the quality is sacrificed, it will be a bit more than worth the loss. In fact, the control speed of metal laser cutting machine is not so simple. The cutting speed often needs to be tested according to a range provided by the manufacturer’s technology to find the appropriate cutting speed. Because of the different thickness, composition, ductility and thermal conductivity of cutting materials, the cutting speed is also different. General performance:
1. The proper increase of the speed of the laser cutting machine can not only improve the quality of the cutting seam, but also reduce the deformation of the cutting seam.
2. If the cutting speed is too fast, the cutting linear energy will be lower than the required value. If the gas blowing cannot blow the molten material away quickly during the cutting process, a large amount of drag will be formed, which will affect the integrity of the cut, and even may require secondary treatment.
3. If the speed of the laser cutting machine is too low, the cutting point will be exposed to the high temperature of the laser for a long time, which not only causes the cutting seam to become larger, but also may affect the beauty of the cutting seam due to too much heat conduction, and form slag on the back of the metal.
4. When the speed is very low, the cut will melt too much, the cut seam will be wider, and even the arc will be extinguished and the cutting will not be possible.
Therefore, the cutting speed will affect the cutting quality, not just from the cutting speed. I hope you should be careful when operating the metal laser cutting machine.
