With the continuous development of the industry, the metal manufacturing industry has put forward new requirements for the accuracy, speed and thickness of sheet metal cutting. The power achieved by fiber laser cutting machines is getting higher and higher. Many customers will ask how to choose the power of the fiber laser cutting machine when purchasing the machine. This article will introduce you how to choose and buy metal laser cutting machines from various aspects.
Influence of processing material and cutting thickness on laser power
The power selection of the fiber laser cutting machine has a great relationship with the actual processing material and the actual cutting thickness. Lasers have different effects on different metal materials, and the laser power varies with metal materials. For example, at the same thickness, the laser power for cutting carbon steel is lower than that for stainless steel, and the laser power for cutting stainless steel is lower than that for brass. In addition to the characteristics of the metal itself, the laser power is also closely related to the thickness of the material. For the same sheet metal, the cutting power of 10mm is lower than 20mm.
Cut thickness also affects the finish of the cut surface of the sheet metal. In addition to material thickness, the auxiliary gas used will also have an impact on the laser cutting surface. To ensure that metal plates below 3mm are cut without burrs, nitrogen is the best gas, followed by oxygen, and air is the worst.
Laser Power Selection
There are many mainstream metal cutting machines on the market, ranging from 1000W to 20000W. Most metal manufacturers have sheet thicknesses between 8mm-12mm. If cutting this thickness for a long time, it is recommended to choose a 4000W-6000W laser cutting machine. If it is brass with high reflection characteristics, it is recommended to use a laser cutting machine with a power of more than 6000W. It is recommended to use a 2000W-4000W laser cutting machine for metal sheets with a thickness of 5mm-8mm. 1000W laser generator cutting machine.
How to choose the right laser cutting machine
Laser cutting machines can be divided into low, medium and high power according to power. For thinner stainless steel and carbon steel plates, low-power fiber laser cutting machines can be used to cut well, while ensuring high cutting speed, which not only ensures work efficiency, but also saves costs.
Therefore, when choosing a laser cutting machine, you must make a reasonable choice according to your own material properties and material thickness, and do not blindly pursue high power. High-power laser cutting machines have higher requirements on hardware. The upgrade of the whole machine will make the price of the machine very expensive. Therefore, when choosing the power of metal cutting equipment, you should consider your own budget.
Of course, if you have thick metal plates to process, and the output is large, it is also a better choice to buy a high-power laser cutting machine within the price range you can afford. Because by adjusting the cutting speed and appropriately changing the auxiliary gas, the high-power laser cutting machine can well improve the cutting quality and work efficiency.
