Today, we will provide a detailed introduction on how to adjust the parameters of a 30000 watt laser cutting machine so that you can successfully cut 55mm thick aluminum plates.

Cutting mouth selection
Firstly, we need to choose a suitable cutting nozzle. For aluminum plates of such thickness, it is recommended to use the largest diameter cutting nozzle, such as 5.0, 7.0, or 10.0.

Cutting speed
Due to the large thickness of the aluminum plate, the cutting speed may be slower. It is recommended to set the speed to 0.3.

Cutting height
The range of cutting height should be set between 0.3 and 0.5, and we recommend using 0.3.

Air pressure setting
For a 10.0 nozzle, the air pressure is usually set between 5 and 6, and we recommend setting the air pressure to 5.

laser power 
The laser power should be set to full power, but special attention should be paid to frequency and duty cycle when cutting aluminum plates.

frequency

The frequency for cutting such thick aluminum plates should be set between 200 and 500. For a 55mm thick aluminum plate, it is recommended to set the frequency to 200.

Duty cycle

To ensure the quality of the cutting surface and reduce burrs, the duty cycle needs to be set between 38 and 48. We suggest setting the duty cycle to 40.

Focus adjustment
The focus should be set to a negative number. Based on past experience, it is recommended to set the focus to -25.
Perforation and lead technology
During the perforation process, some debris may appear. At this point, the lead wire process can be referenced to initiate the lead wire slow down cutting parameters.

① Cutting speed: Slow down a bit, it is recommended to set it to 0.1.

② Duty cycle: Same as the cutting parameters, set to 40.

③ Frequency: Same as cutting parameters, set to 200.

④ Stable distance: set to 0.

⑤ Lead height: Set between 5 and 10, we recommend setting it to 8.

After completing the above parameter settings, click OK to start cutting the 55mm thick aluminum plate.
By adjusting these detailed parameters, you can achieve high-quality aluminum plate cutting results when using a 30000 watt laser cutting machine. If you have any questions or need further technical support, please feel free to contact us at any time.
