In determining which after a long lens focal focal point and the relative position of the workpiece surface is particularly important to ensure the quality of cutting.
Distance between nozzle and workpiece surface usually is 1.
About 5 mm.
the other through practice shows that when the auxiliary gas for oxygen, the purity of it has a significant effect on cutting quality.
but customers in the use of laser cutting machine, occasionally flush cutting result is bad, in this case, ruled out the cause of the fault with the device itself, then we in the topic of how to solve the cutting effect is not good? Reality, cutting effect is related to technology, mainly including cutting speed, focus position and auxiliary gas these three process parameters, the high energy laser is to teach people to solve the 'laser cutting machine cutting result is bad to do,' the title of the!
the effects of cutting speed on cutting quality
for the given laser power density and material, cutting speed corresponds to an empirical formula, as long as the above access threshold, material cutting speed is proportional to the laser power density, the cutting speed increase power density can be progress. In addition, the beam is focused on the characteristics of the system, namely after focusing spot size also has great influence on laser cutting.
auxiliary gas pressure influence on cutting quality
in general, the material you need to use auxiliary gas cutting, subject mainly involves the type of auxiliary gas and pressure. Sometimes, cutting speed slow can also cause discharge hot melt material ablation surface, the plane is very coarse. Because of the high focus in power density, in most cases, the focus position just in cutting the workpiece surface, or slightly below the surface.
special for metal materials, in the case of other process variables constant, laser cutting speed can have a relatively adjusting range remained more satisfy the cutting quality, and the adjusting range when cutting thin metal is a slightly wider than thick.
to use the reactive gas most metal laser cutting, forming and hot metal oxidation exothermic reaction, the department added heat 1/3 ~ 1/2 the cutting speed can be progress. When high-speed cutting thin materials, high gas pressure are needed to prevent the burrs on the incision on the back of the hang slag, when the thickness of the material increase or the cutting speed is slower when the gas pressure should be appropriately reduced. The oxygen purity 2% reduction can reduce 50% of the cutting speed, and led to the significant variation of the quality of the incision. For metallic materials, non-metallic materials and departments use compressed air or inert gases, dealing with melting and evaporation materials, bay cutting area is excessive burning at the same time. Sometimes, lens work because of poor cooling and heat causing focal length change, it's need to adjust the focus position.
the cutting speed and laser cutting machine is cutting material density ( The proportion of) And is inversely proportional to the thickness. Because long telephoto lens has a wide depth of focus, as long as have the enough power density, suitable for cutting thick artifacts. Here refers to not only related to the laser output power, power density and related to the model of beam quality. After focusing the laser beam spot size is directly proportional to the lens JiaoChangCheng, after short focal length lens to focus the light beam spot size is small, the focus in high power density, the material cutting is strong; But its drawback is that the depth is very short, adjust the margin is small, is generally used in high speed cutting thin materials. In the whole cutting process, to ensure focus and workpiece position relatively constant is the important premise of cutting quality to obtain not disorderly.
the focus position adjustment's influence on the cutting quality
as a great influence on cutting speed and laser power density lens focal length selection is an important topic.
laser cutting machine applied in most cases, the light beam focus to just under the nozzle. Usually, auxiliary gas and laser beam coaxial jet, protect the lens from pollution and blow away the cutting area at the bottom of the slag.
laser cutting machine under the condition of ensure the auxiliary gas, gas pressure is a very important factor. When the other parameters remain unchanged, cutting speed factor is: progressive power ( In a certain range, such as 500 ~ 2000 w) ； To improve the beam pattern ( Such as from neglected to the low order modes until TEM00) ； Reduce the focus spot size, such as using a short focal length lens focusing.
when focus is in a better position, laser cutting machine cutting small, high efficiency, better cutting speed can be obtained better cutting results.
