From 1000W fiber laser cutting machine to 8000W , and then to the 10,000W laser cutting machine that once seemed out of reach, the power of laser cutting machines has exceeded imagination step by step. In the past, the thickness of fiber laser cutting plates was limited to 20mm for carbon steel and 12mm for stainless steel. However, 10,000W laser cutting machines can cut aluminum alloy plates up to 40mm and stainless steel plates up to 50mm.
When cutting stainless steel plates with a thickness of 3~10mm, the cutting speed of a 10kW laser cutting machine is more than twice that of a 6kW laser cutting machine. At the same time, in the cutting application of carbon steel, Wanwa laser cutting machine can achieve fast bright surface cutting of 18-20mm/s, which is twice the ordinary standard cutting speed. Compressed air or nitrogen can also be used to cut carbon steel within 12mm, and the cutting efficiency is 6-7 times that of oxygen cutting carbon steel.
Data shows that in terms of 8mm stainless steel, the speed of 6kW laser cutting machine is nearly 400% higher than that of 3kW laser cutting machine. In terms of 20mm thick stainless steel, the speed of 12kW increased by 114% compared to 10kW.
From the perspective of economic benefits, the price of a 10,000-watt laser cutting equipment is less than 40% higher than the price of a 6kW machine tool, but the output efficiency per unit time is more than twice that of a 6kW equipment, and it saves labor and space. , so it is favored by owners of laser processing companies.
Laser cutting machines are suitable for stainless steel, carbon steel, alloy steel, aluminum plates, silver, copper, titanium and other metal materials. For different metal materials, the cutting thickness of different power laser cutting machines has a great relationship with the cutting material.
For different laser cutting machine powers, the thickness limits for cutting various materials are as follows (for reference only, the actual cutting capacity is also affected by cutting quality, cutting environment, auxiliary gas, cutting speed and other factors):
Maximum thickness of different materials for 500W fiber laser cutting machine:
Carbon steel maximum thickness 6mm
Stainless steel maximum thickness 3mm
Maximum thickness of aluminum plate 2mm
Maximum thickness of copper plate 2mm
Maximum thickness of different materials cut by 1000W fiber laser cutting machine:
Carbon steel maximum thickness 10mm
Stainless steel maximum thickness 5mm
Aluminum plate maximum thickness 3mm
The maximum thickness of copper plate is 3mm
Maximum thickness of different materials cut by 2000W fiber laser cutting machine:
Carbon steel maximum thickness 16mm
Stainless steel maximum thickness 8mm
Aluminum plate maximum thickness 5mm
Maximum thickness of copper plate 5mm
Maximum thickness of different materials cut by 3000W fiber laser cutting machine:
Carbon steel maximum thickness 20mm
Stainless steel maximum thickness 10mm
Aluminum plate maximum thickness 8mm
The maximum thickness of copper plate is 8mm
The maximum thickness of 4500W laser cutting stainless steel is 20mm, but the cutting quality above 12mm is not guaranteed, and the cutting below 12mm is bright surface cutting. The cutting capacity of 6000W will be better, but the price will also be higher.
In practical applications, the cutting ability of fiber laser cutting machines is also affected by many factors such as cutting machine quality, laser type, cutting environment, cutting speed, etc. The use of auxiliary gas can also improve certain cutting capabilities.
Therefore, there is no absolute standard for judging 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.
Generally speaking, a 1000W fiber laser cutting machine can cut carbon steel plates of about 10mm, while stainless steel plates are slightly more difficult to cut. Increased cutting thickness may come at the expense of edge quality and speed.
