The impact of cutting speed of fiber laser cutting machine on processing quality

Many friends are not unfamiliar with fiber laser Cutting Machine, fiber laser cutting machine processing not only cutting fine, but also has the characteristics of fast cutting speed. However, the faster the cutting speed is not the better, under certain conditions of laser power, fiber laser cutting machine is the best cutting speed range, too fast or too slow will have a different impact on the quality of the processed surface. The following follow the GOLD MARK laser to see what impact the cutting speed will have on the cutting quality.Cutting speed has a great impact on the quality of stainless steel sheet cutting, the best cutting speed so that the cutting surface is a smoother line, smooth and the lower part of the slag-free production. If the cutting speed is too fast, it will lead to the steel plate can not cut through, causing sparks splash, the lower part of the slag, and even burn the lens, which is because the cutting spseed is too high, the energy obtained per unit area is reduced, the metal failed to completely melt; if the cutting speed is too slow, it is easy to cause the material to over-melt, the slit becomes wider, the heat-affected zone increases, and even cause the workpiece to overburn, which is because the cutting speed is too low, the energy accumulates at the slit This is because the cutting speed is too low, the energy accumulates at the slit, causing the slit to widen, the molten metal can not be discharged in time, it will form a slag on the lower surface of the steel plate.Cutting speed and laser output power together determine the input heat of the processed part. Therefore, the relationship between the change in heat input and processing quality due to the increase or decrease in cutting speed is the same as that of the change in output power. In general, when adjusting the processing conditions, if the purpose is to change the input heat, the output power and cutting speed will not be changed at the same time, only one of them should be fixed and the other one should be changed to adjust the processing quality.Guangdong China cut CNC Machinery Co., Ltd. is a high-tech industry enterprise specialized in researching, manufacturing and selling the machines as follows: Laser Engraver, Fiber Laser Marking Machine, CNC Router.
