Generally speaking, the thickness limit values for cutting various materials with different laser cutting machine powers are as follows:

(For reference only, the actual cutting ability is also related to various factors such as cutting machine quality, cutting environment, auxiliary gas, cutting speed, etc.)

1. The maximum cutting thickness of different materials for a 2000W fiber laser cutting machine: carbon steel, with a maximum thickness of 16mm; The maximum thickness of stainless steel is 6mm; The maximum thickness of aluminum plate is 4mm; The maximum thickness of copper plate is 4mm;

2. 3000W fiber laser cutting machine, maximum thickness for cutting different materials: carbon steel, maximum thickness 22mm; The maximum thickness of stainless steel is 12mm; The maximum thickness of aluminum plate is 8mm; The maximum thickness of copper plate is 8mm;

3. 4000W fiber laser cutting machine, maximum cutting thickness for different materials: carbon steel, maximum thickness 25mm; The maximum thickness of stainless steel is 12mm; The maximum thickness of aluminum plate is 10mm; The maximum thickness of copper plate is 10mm;

4. 6000W fiber laser cutting machine, maximum cutting thickness for different materials: carbon steel, maximum thickness 25mm; The maximum thickness of stainless steel is 20mm; The maximum thickness of aluminum plate is 16mm; The maximum thickness of copper plate is 12mm;

12000W laser cutting of stainless steel can reach a maximum of 40mm, but the quality of the cutting surface above 25mm is not guaranteed. Cutting below 25mm is definitely a bright surface cutting. A cutting capacity of 15000W would be better, but the price is also higher.

In the practical application process, the cutting ability of fiber laser cutting machines is also related to various factors such as cutting machine quality, laser type, cutting environment, cutting speed, etc. The use of auxiliary gas can also improve a certain cutting ability, so there is no absolute standard to determine its cutting thickness. For example, 1. The cutting of carbon steel mainly relies on oxygen combustion, 2. The cutting of stainless steel mainly relies on power. The general 3000W fiber laser cutting machine can cut carbon steel plates of around 22mm, while stainless steel plates are slightly difficult to cut. To increase the cutting thickness, it is necessary to sacrifice edge effect and speed.
