When debugging the process of cutting carbon steel with a 6000-watt fiber laser cutting machine, we chose a double-layer 1.2e nozzle. First, we will perform the perforation operation, using the first-level power for perforation, setting the height to 12, the air pressure to 1, the power to the maximum, the duty cycle to 45% to 55%, and the frequency to 3000. The choice of focus is roughly proportional to the thickness of the plate. For example, for the first 9mm plate, we choose the focus to be -6, and then the remaining dwell time is set to 200. Next, we will perform a perforation test. By using the above parameters, we can quickly penetrate the plate and observe that the perforation aperture is small and delicate. Such a perforation effect can already meet our requirements.

How thick a plate do you think a 6000-watt fiber laser cutting machine is suitable for cutting? Okay, let's try it.

We tried to run at maximum speed and ran a straight line of 2.8 meters. By observing the sparks generated by the cutting head of the fiber laser cutting machine, it can be clearly seen that the sparks splash along the plate obliquely to one side. This indicates that the cutting head is working properly and the sparks are moving in the cutting direction. If you want to cut a bright surface, the speed must be faster than normal, and the speed can be adjusted by observing the tracking of the sparks. The surface cut by the fiber laser cutting machine will be very bright, smooth and shiny.

In summary, if you want the fiber laser cutting machine to cut a bright surface, you need to speed up, and you don’t need to set too much power, otherwise it may produce virtual slag, and the virtual slag is difficult to remove. Please note that the above content is organized according to the information you provide, and the specific process parameters and debugging process may need to be adjusted according to the actual situation and the characteristics of the machine. It is recommended to conduct a small-scale test and debugging before actual operation to ensure the ideal fiber laser cutting machine cutting effect.
