Fiber Laser Cutting Machines: How to Choose the Power?

Guide: Fiber laser cutting machines with different power ratings exhibit varying cutting capabilities and thickness ranges. So, how should one select the appropriate power when choosing a fiber laser cutting machine?

Fiber laser cutting machines offer distinct advantages in sheet metal blanking. They utilize the high temperatures generated by lasers to melt the surface of sheet metal components, achieving cutting through CNC-controlled displacement. The primary advantages of laser processing include minimal deformation, high flexibility, narrow kerf width, smooth burr-free edges, and the ability to cut arbitrarily complex shapes. For different sheet thicknesses, power significantly influences kerf quality and cutting speed.

Taking carbon steel as an example: - For carbon steel below 2mm thickness, the maximum cutting speed with a 500W machine is approximately 6.6 meters per minute, while a 1000W machine achieves about 8 meters per minute. For 6mm carbon steel, the maximum cutting speed with a 500W machine is approximately 0.8 meters per minute, while a 1000W machine achieves about 1.6 meters per minute. Similar trends apply to other thicknesses.

Next, using stainless steel as an example, as shown in the figure, the maximum cutting speed for stainless steel under 2mm using a 500W machine is approximately 8 meters per minute, while the maximum speed using a 1000W machine reaches about 17 meters per minute; For stainless steel around 3mm thick, the maximum cutting speed with a 500W machine is approximately 0.4 meters per minute, while a 1000W machine achieves about 1.4 meters per minute—a significant difference.

Therefore, when comparing 500W and 1000W fiber laser cutting machines, the 1000W fiber laser cutting machine is clearly the wiser choice.
