How to choose the power of fiber laser cutting machine

by:VENTECH     2021-12-22


Different power fiber laser cutting machines have different cutting capabilities and cutting thickness ranges. So, when choosing the right fiber laser cutting machine, how to choose its power? Let's take everyone to understand.



Fiber laser cutting machine has a relatively prominent advantage in sheet metal blanking. It relies on the high temperature generated by the laser to melt the surface of the sheet metal part and achieve the purpose of cutting through numerical control of the displacement. The advantages of laser processing are mainly reflected in the fact that there is no deformation, high flexibility, small slitting, smooth section without burrs, and it can cut arbitrarily complex graphics workpieces. Then, for different plate thicknesses, power plays an important determinant of the quality and speed of the slit.



Let’s take the common 500W-1000W as an example, and give you an analysis:





The comparison chart of cutting process parameters of 500W and 1000W fiber laser cutting machines. Take the carbon steel material as an example. As shown in the figure, the maximum speed for cutting carbon steel below 2mm with a 500W machine is about 6.6 meters per minute, and the maximum speed for cutting with a 1000W machine is about 8 meters per minute; 6mm carbon steel is used The maximum speed of 500W machine cutting is about 0.8 meters per minute, the maximum speed of using 1000W machine cutting is about 1.6 meters per minute, and so on.



Next, take stainless steel as an example. As shown in the figure, the maximum speed of stainless steel under 2mm using a 500W machine is about 8 meters per minute, while the maximum speed of using a 1000W machine can reach 17 meters per minute. About; the maximum speed of stainless steel about 3mm using a 500W machine is about 0.4 meters per minute, and the maximum speed of using a 1000W machine is about 1.4 meters per minute, the difference is very obvious. It can be seen that when facing the 500W and 1000W fiber laser cutting machines, the 1000W fiber laser cutting machine is obviously a more sensible choice.



Most of the metal plates/tubes processed by laser cutting machines on the market are below 16mm, and a few will exceed this thickness.



1) It is recommended to choose 4000W-6000W if the thickness is more than 12mm for frequent processing;



2) Thickness 8-10mm, 1500W-3000W optional;



3) Thickness 5-8mm, 1000-2000W optional.



4) Small thickness can be 500-1000W. This type of power range is often cost-effective



It is strongly recommended to bring your own materials to the manufacturer for proofing and cutting before making a decision.
