How to choose laser power for fiber laser cutting machine?

Fiber laser cutting machine has outstanding advantages in sheet metal cutting. It relies on the high temperature melting generated by laser to irradiate the surface of metal sheet and achieves the purpose of cutting through numerical control displacement. The advantages of laser cutting are no deformation, high flexibility, small cutting seam, smooth cross section, no burrs, and can cut any complex graphic work piece. For different sheet thicknesses, power plays an important role in cutting quality and speed.

Fiber laser cutting machines of different powers have different cutting capabilities and thickness ranges. Therefore, when choosing a suitable fiber laser cutting machine, the corresponding configuration of the fiber laser cutting machine is usually selected according to the material to be processed and cut.

The materials cut by fiber laser cutting machines are metals, mainly stainless steel, carbon steel, aluminum, brass, etc. The achievable cutting thickness increases with the increase of laser power.

The power of a fiber laser cutting machine mainly depends on the laser source. In the market, 4000W and above are generally called high power.

2000W-4000W are called medium power, and 2000W and below are called low power. From the current demand, the market demand for 2000W fiber laser cutting machines is relatively large, which can meet most cutting needs.

The cutting speed above 4000W may be faster, but it is also more expensive. Laser power is one of the main factors that directly affect the price of laser cutting machines.

Let's take carbon steel as an example. A 1000W machine can cut carbon steel below 8mm, and a 1500W machine can cut carbon steel below 12mm. Next, let's take stainless steel as an example. A 1000W machine can cut stainless steel below 4mm, and a 1500W machine can reach about 6mm. It can be seen that when faced with a 1000W and 1500W fiber laser cutting machine, a 1500W fiber laser cutting machine is a wiser choice.
