What is the maximum thickness laser can cut?

HF-A metal cutting laser machine

With the rapid development of laser sheet cutting machine technology and the gradual intensification of competition, more and more high-power cnc metal sheet cutting machine have been developed. The available laser power can reach 30000w or higher, and it is possible to cut sheets with a thickness of 1 mm or even 100 mm thick. In this post, we will walk through the maximum thickness that the most often used fiber cutting machine with different laser wattage can cut.

● Compared with the CO2 laser cutting machine, this fiber laser has a shorter wavelength, so it has better absorption characteristics, and the focused beam of the laser cutting machine has a higher power density at the focal point.
● The fiber laser cutting machine uses nitrogen as auxiliary gas, which can speed up the melting and expelling of materials, thereby increasing the feeding speed.

The maximum cutting thickness of different materials for 12kw fiber laser cutting machine: stainless steel maximum thickness 35mm; aluminum material maximum thickness 35mm; carbon steel maximum thickness 40mm.

For stainless steel, the cutting speed of the 120000w fiber laser cutting machine ranges from 0.1m/min to 50m/min. For aluminum, the cutting speed ranges from 0.1m/min to 50m/min.  For carbon steel, the cutting speed ranges from 0.1m/min to 10m/min.

Reminder:
① If the graphics are simple and do not require high accuracy, then you can cut the plates in batches.
② If you have good operator adjustments and machine conditions, you can get the laser cutting thickness limit of cutting speed and accuracy.

 

Conclusion

To obtain high-precision and high-speed cutting, in addition to the fiber laser machine itself, the operator also needs to adjust the parameters properly, such as laser power, gas pressure, feed rate, the working distance of the nozzle and focus position, etc. Different operations will lead to different cutting results, but it is certain that whether you need to process copper/brass, aluminum, stainless steel and carbon steel of different thicknesses, fiber laser cnc machine from the Hymson sheet metal cutting machine manufacturers must be your economical choice.
