​Comparison of cutting material and thickness of fiber laser cutting machine

XT Laser Cutting Machine

A laser cutting machine uses a focused high-power density laser beam to irradiate a workpiece, causing the irradiated material to quickly melt, ablate, or reach the ignition point. At the same time, it uses a high-speed airflow coaxial with the beam to blow away the molten material, thereby achieving the cutting of the workpiece. Laser cutting is one of the thermal cutting methods. The upper limit value for cutting thickness varies with different power laser cutting machines. In theory, it is better to choose a higher power laser cutting machine. However, in practical applications, there are more reasonable choices. For example, using a high-power laser cutting machine to cut metal sheets is clearly not the most economical method. Below, an analysis is conducted on the cutting thickness of different power laser cutting machines, including stainless steel, carbon steel, alloy steel, aluminum plate, silver, copper, etc Titanium and other metal materials.

The cutting thickness of laser cutting machines with different powers for different metal materials is closely related to the cutting materials. How thick can laser cutting machines of various power ranges, such as 500W fiber laser cutting machine, 1000W fiber laser cutting machine, 2000W fiber laser cutting machine, 3000W fiber laser cutting machine, etc., cut?

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 500W fiber laser cutting machine: 6mm for carbon steel; The maximum thickness of stainless steel is 3mm; The maximum thickness of aluminum plate is 2mm; Maximum thickness of copper plate 2mm

2. 1000W fiber laser cutting machine, maximum cutting thickness for different materials: carbon steel, maximum thickness 10mm; The maximum thickness of stainless steel is 5mm; The maximum thickness of aluminum plate is 3mm; Maximum thickness of copper plate 3mm

3. 2000W fiber laser cutting machine, maximum thickness for cutting different materials: carbon steel, maximum thickness 16mm; The maximum thickness of stainless steel is 8mm; The maximum thickness of aluminum plate is 5mm; The maximum thickness of copper plate is 5mm

4. 3000W fiber laser cutting machine, maximum thickness for cutting different materials: 20mm maximum thickness for carbon steel; The maximum thickness of stainless steel is 10mm; The maximum thickness of aluminum plate is 8mm; The maximum thickness of copper plate is 8mm

5. 4500W laser cutting of stainless steel can reach a maximum of 20mm, but the quality of the cutting surface above 12mm is not good, ensuring that cutting below 12mm is definitely a bright surface cutting. A cutting capacity of 6000W 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, the cutting of carbon steel mainly relies on oxygen combustion, while the cutting of stainless steel mainly relies on power. A general 1000W fiber laser cutting machine can cut carbon steel plates of about 10mm, while stainless steel plates are slightly difficult to cut. To increase the cutting thickness, it is necessary to sacrifice edge effect and speed.
