In the world market, laser cutting machines are developing towards high-power, large format, and thick sheet metal. With the advancement of major projects such as railway construction, highway construction, water conservancy construction, hydropower construction, energy, mining construction, and construction industry in China, large format thick sheet metal laser cutting machines will be widely used in the construction machinery industry. However, towards industrial applications, ultra-high power laser cutting machines still need to overcome four major technical challenges:

One is the light source technology, which not only generates a stable output of 10000 watts of laser, but also couples this high laser power into an optical fiber with a diameter of 0.1mm.

The second is laser cutting head technology, in which the internal conductive lens must withstand high energy penetration and require good airtightness and special high-pressure nozzles.

The third is the high dynamic performance and thermal management technology of the machine tool. The design of the high dynamic machine tool and the development of the latest control software SM4.0 make it meet the above requirements. At the same time, measures should be taken to manage the heat absorption, heat conduction, and heat penetration of the machine tool, maintain the stability of the machine tool accuracy and service life.

The fourth is the study of process parameters for laser cutting, which requires selecting the optimal parameters to ensure maximum cutting capacity, optimal cross-sectional quality, and fastest cutting speed.
