Precautions for bright surface cutting by fiber laser cutting machine

Fiber laser Cutting Machine is widely used in industrial production, sometimes we will find that some metal cutting surface is very smooth, such as a mirror, in fact, in the laser cutting process technology, the cutting surface of carbon steel can be cut very smooth, like a mirror-like effect, commonly known as “bright surface cutting”. Bright surface cutting is mainly used for medium thickness carbon steel, the steel plate is too thin or too thick can not achieve bright surface cutting. So what should we pay attention to when we carry out bright cutting? Here follow GOLD MARK to understand.1, to control the cutting speed. Too fast a cutting speed will lead to incomplete material burning, the workpiece can not be cut through, while too slow a speed will lead to excessive burning, so that the workpiece melting deformation. Under the premise of ensuring that the workpiece will be, the cutting speed should be increased as much as possible.2, adjust the nozzle height. Nozzle height will affect the beam quality, oxygen purity and gas flow, when the lower the nozzle, the better the beam quality, the higher the oxygen purity, the smaller the gas flow, so the bright surface cutting should try to adjust the height of the lower.3, adjust the cutting air pressure. In the oxygen cutting of carbon steel, the combustion of the material will give off a lot of heat, so the oxygen air pressure should not be too large. Generally speaking, the lower the air pressure in the cuttable range, the brighter the cut section, but in order to ensure cutting stability, usually increase a certain percentage on the basis of the cut-off air pressure.4, adjust the cutting power. For different thickness of the plate, the greater the thickness, the higher the power required.5, adjust the size of the cutting focus. Fiber laser by the nozzle ejected beam is a certain diameter, in bright surface cutting, usually use the nozzle is smaller. If the focal point is too large, it will lead to nozzle hot, affecting the quality and stability of cutting, and in serious cases can even directly lead to nozzle damage. Therefore need to find out the size of the nozzle can withstand the focus value, and then adjust.6, choose the size of the nozzle. Half of the nozzle is smaller, the brighter the cut section, the better the effect.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.
