Fiber laser cutting machine, as a high-precision and high-efficiency processing equipment, is widely used in the field of metal sheet cutting. However, in practical operation, the relationship between the power of the laser cutting machine and the thickness of the sheet is a key element that the operator must master. This article will explore the intrinsic connection between the two, in order to provide reference for technical personnel in related fields.

The power of a fiber laser cutting machine directly determines its cutting ability. Generally speaking, the higher the power, the stronger the energy of the laser beam, and the thicker the cut sheet. For example, a 1000 watt fiber laser cutting machine can cut carbon steel plates with a maximum thickness of about 10 millimeters, while the cutting thickness of stainless steel plates is slightly lower, about 5 millimeters. When the power is increased to 20 million, the cutting thickness of carbon steel plate can be increased to 16 millimeters, and stainless steel plate can also reach 8 millimeters.

However, the relationship between power and sheet thickness is not simply a linear increase. As the thickness of the sheet increases, the difficulty of laser cutting also increases. On the one hand, thick sheets require higher energy density to be effectively cut, which requires laser cutting machines to have higher power output. On the other hand, during the cutting process of thick plates, the penetration depth and focusing effect of the laser beam may be affected to some extent, which may lead to a decrease in cutting quality.

In addition, the power requirements for laser cutting machines vary depending on the material of the sheet. For example, materials with good thermal conductivity such as aluminum alloy and copper require higher laser power to ensure cutting quality. For materials with poor thermal conductivity such as stainless steel and carbon steel, although the cutting power can be relatively low, it still needs to be adjusted appropriately according to the thickness of the plate.

In practical operation, the operator should choose the power of the laser cutting machine reasonably according to the material and thickness of the board. Low power may result in slow cutting speed, while high power may cause overheating, deformation, or even damage to the sheet metal. Therefore, when selecting the power of a laser cutting machine, full consideration should be given to the cutting requirements and quality requirements of the sheet metal.

In summary, there is a close relationship between the power of fiber laser cutting machines and the thickness of the sheet metal. The operator should choose the power of the laser cutting machine reasonably based on actual needs and the characteristics of the board to ensure cutting quality and production efficiency. Meanwhile, with the continuous advancement of technology and the upgrading of equipment, the cutting capability and application scope of fiber laser cutting machines will also continue to expand.
