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 that fiber laser cutting machine can reach is getting higher and higher. Many users will ask how to choose the power of the fiber laser cutting machine when buying the machine. This post will introduce you how to buy a metal laser cutting machine from many aspects.

 

The 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. The laser has different effects on different metal materials, and the laser power varies with the metal material.

For example, under the same thickness, the laser power for cutting carbon steel is lower than that of stainless steel, and the laser power for cutting stainless steel is lower than that of 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. The cutting thickness also affects the smoothness of the cut surface of the sheet metal.

 

Selection of core components of laser cutting machine

Lasers generally have the German IPG brand and China Raycus. Different brands have their own advantages. When you choose a fiber laser cutting machine, you can understand the difference between the two with the staff before making a choice. The laser cutting head has auto focus and manual focus, you can buy it according to your work needs. At the same time, pay attention to other parts of laser cutting, such as whether the motor is imported servo motor, the performance of the guide rail, the weight of the bed, etc., which affect the cutting accuracy of the machine to a certain extent.

 

Laser power selection

There are many mainstream metal cutting machines on the market, ranging from 1000W to 20000W. Most metal manufacturers' sheet thicknesses are between 8mm-12mm. If cutting this thickness for a long time, it is recommended to choose 4000W-6000W laser cutting machine. If it is high-reflective brass, it is recommended to use a laser cutting machine with a power above 6000W. It is recommended to use a 2000W-4000W laser cutting machine for metal sheets with a thickness of 5mm-8mm. A 1000W laser generator is usually sufficient for cutting sheets of lower thickness.

 

How to choose the right laser cutting machine

Laser cutting machines can be divided into low, medium and high power according to the power. For thinner stainless steel and carbon steel plates, a low-power fiber laser cutting machine can be used to cut well, while ensuring a higher cutting speed, which not only ensures work efficiency, but also saves costs.

Of course, if you have thick metal plates to be processed 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.

 

Fiber laser cutting machine has become the mainstream machine in the metal manufacturing industry. Choosing a suitable metal cutting equipment will bring higher output to your workshop.
