Fiber Laser Cutting Thickness & Wattage Requirements

The laser cutting machine for mass production and processing can cut the maximum thickness of different material boards as shown in the figure (thickness unit mm):

The laser cutting thickness chart as follows:

As shown in the above list, the thickest boards of various materials that can be cut by fiber laser cutting machines of different powers in mass production are different.

1. 500W fiber laser power

Under the condition of ensuring the stable operation of the machine, considering that the minimum cutting speed should reach about 1 meter, it is recommended to cut the stainless steel plate with a maximum thickness of 2 mm, and the cutting speed can reach 2.7 meters per minute. The maximum thickness of the cutting carbon steel plate is 5mm, and the cutting speed is 1 m/min.

In actual processing, it is generally not recommended that customers choose 500W to cut aluminum alloy plates and copper plates.

2. 1000W laser power

Usually, customers choose to use a stable laser to process and cut workpieces in large quantities. It is recommended to cut stainless steel plates with a maximum cutting thickness of 4mm and a cutting speed of 1 m/min. The maximum thickness of the cutting carbon steel plate is 8mm, and the cutting speed will be 1.1 m/min. For cutting aluminum alloy plates, 1000W fiber laser power can cut the maximum thickness of 3mm, and the cutting speed is 1.5m/min. When cutting copper plates, the maximum plate thickness that can be stably cut with 1000W laser power is 2mm, and the cutting speed is 2m/min.

3. 1500W fiber laser power 

It is recommended that when customers use 1500W laser power to cut the board, the maximum cutting thickness of the stainless steel plate is 5mm, and the cutting speed is 1.5m/min. The maximum thickness of the cutting carbon steel plate is 12mm, and the cutting speed is 0.8 m/min. The maximum thickness of the cutting aluminum alloy plate is 3mm, and the cutting speed is 2.5 m/min. This cutting speed is still relatively fast. When cutting copper plates, the maximum plate thickness that can be stably cut with 1500W fiber laser power is also 3mm, and the cutting speed is 1.8 m/min.

4. 2000W laser power 

When the customer chooses 2000W fiber laser power to cut the board, it is recommended to cut the stainless steel plate with a maximum cutting thickness of 6mm, and the cutting speed is usually 1.5m/min. The maximum thickness of the cutting carbon steel plate is 16mm, and the cutting speed is 0.7 m/min. The maximum thickness of the cutting aluminum alloy plate can be cut to 4mm, and the cutting speed is 1.5m/min. The maximum thickness of the cut copper plate is also 4mm, and the cutting speed is 1.3 m/min.

5. 3000W fiber laser power 

When customers choose 3000W laser power to cut the board, it is recommended to cut the stainless steel plate with a maximum cutting thickness of 8mm and a cutting speed of 1.2 m/min. The maximum thickness of the cutting carbon steel plate is 20mm, and the cutting speed will be 0.55-0.65 m/min. The maximum thickness of the cutting aluminum alloy plate can be cut 6mm with 3000W, and the cutting speed is 2m/min. When cutting copper plates, the maximum plate thickness for stable cutting is also 6mm, and the cutting speed is 1.3 m/min.

6. 4000W laser power

When the customer chooses to cut the board with 4000W laser power, the maximum cutting thickness of the stainless steel plate is 10mm, and the cutting speed is 1.2m/min. The maximum thickness of the cutting carbon steel plate is 22mm, and the cutting speed is 0.6 m/min. The maximum thickness of the cutting aluminum alloy plate can be cut to 8mm, and the cutting speed is 1.3 m/min. The maximum thickness of the cutting copper plate for stable cutting is also 8mm, and the cutting speed is 1 m/min.

7. 6000W fiber laser power 

In the choice of 6000W laser power cutting board, we usually recommend a maximum cutting board thickness of 16mm and a cutting speed of 0.6 m/min. The maximum thickness of the cutting carbon steel plate is 22mm, and the cutting speed is 0.55-0.65 m/min. The maximum thickness of the cutting aluminum alloy plate can be cut 12mm, and the cutting speed is 0.7 m/min. The maximum thickness of the cutting copper plate for stable cutting is 10mm, and the cutting speed is 1 m/min.

The cutting ability of a laser cutting machine is determined by its power. The greater the power, the thicker the thickness of the cut sheet.
