Why Is Only Half of The Laser Cutting Workpiece Normal While The Other Half Is Unfinished Or Has Slag, And How Can This Issue Be Resolved?

Recently, there have been reports of laser cutting workpieces showing inconsistent results, with half of the piece being normal and the other half either not cut through or having slag. This issue can be attributed to several factors, such as improper focusing of the laser beam, uneven material thickness, or a dirty or damaged cutting nozzle.

To address this problem, it is important to ensure that the laser beam is properly focused and that the cutting parameters are set correctly for the material being worked on. Additionally, the material should be placed flat on the cutting bed to ensure uniform cutting. Regular maintenance of the cutting nozzle, such as cleaning or replacing it when necessary, can also help prevent slag from forming on the workpiece.

By taking these precautions and addressing the root causes of the issue, manufacturers can ensure consistent and high-quality laser cutting results across the entire workpiece.

(i) Start by checking the hardware and parameters of the fiber laser cutting machine. Ensure that the nozzle is not deformed or has any slag buildup. If the nozzle is damaged, replace it with a new one.

(ii) Next, inspect the protective lens and optical path for any contamination. If there is any dirt or debris present, replace the protective lens promptly to maintain the machine's cutting accuracy.

(iii) Use a coaxial method to check if the laser center point is offset. Gently attach tape to the nozzle and activate the point shooting function to observe the direction of the center point offset. Adjust the machine according to the direction of optical path deviation to realign the laser center point accurately.

In summary, regular maintenance and proper adjustment of the fiber laser cutting machine are essential to ensure optimal cutting performance. As a trusted fiber laser cutting machine supplier, we are committed to providing reliable and efficient laser cutting machines for a wide range of applications.

(iv) If it is still not solved, check the parameters:

When operating a fiber laser cutting machine, it is important to ensure that the speed is not too fast. If the speed is too fast, there is a risk of causing melting and oxidation to not keep up with the cutting process. This can result in a poor quality cut and may damage the material being worked on.

Another important aspect to check is the focus of the laser beam. If the positive focus is set too high, the energy may be insufficient for an effective cut. On the other hand, if the negative focus is too low, the cutting gap may be too small and the slag may not be smooth, which can also affect the quality of the cut.

To avoid these issues, it is essential to regularly check and adjust the speed and focus settings of the laser cutting machine. This will help to ensure that the cutting process is efficient and that the desired results are achieved.

When looking for a fiber laser cutting machine supplier, it is important to choose a reputable and reliable company. They should provide high-quality machines that are suitable for your specific cutting needs. Additionally, they should offer excellent customer support and technical assistance to help you get the most out of your machine.

In conclusion, when using a laser cutting machine, it is crucial to pay attention to the speed and focus settings to ensure optimal cutting results. Choosing a reputable supplier is also important to ensure that you have access to high-quality machines and support. By following these guidelines, you can achieve precise and efficient cuts with your laser cutting machine.
