In recent years, high-power fiber laser cutters have gained significant popularity in the sheet metal processing industry. With the maturity of domestically developed laser technologies, manufacturers now have more accessible and cost-effective solutions for machine production.
Laser cutters with power levels of 3kW, 6kW, and even 12kW have become the top choice for many factories, thanks to their efficiency in cutting medium to thick plates. These machines offer numerous advantages, including computer-controlled precision for material savings, smooth cutting surfaces, and minimal burrs.
However, when it comes to drilling holes in sheet metal, the process imposes higher demands on both the machine and the operator. Improper handling often leads to irregularly shaped holes, a common issue in practical operations.
Common Causes of Round Hole Cutting Failures
1. Improper Light Intensity Adjustment
The difference between maximum and minimum light intensity should not exceed 5%. Running the machine too fast can prevent the cutting path from closing properly, resulting in incomplete holes.
2. Hardware Issues
Worn or damaged components such as lenses, nozzles, or laser heads can significantly affect cutting quality. Regular inspection and maintenance are essential.
3. Incorrect Auxiliary Gas Pressure
If the gas pressure is too low, it can cause rough edges and carbonization. Conversely, excessive pressure may lead to hole bursting. Optimal pressure settings require precise coordination between the operator and machine.
4. Servo Motor Parameter Mismatch
Elliptical or irregular holes often occur due to improper servo motor tuning, causing misalignment with the XY-axis motion. Proper parameter adjustment is crucial for maintaining circular accuracy.
5. Mechanical Accuracy Errors
The precision of guide rails and lead screws plays a critical role. Some smaller manufacturers may claim their machines achieve a positioning accuracy of 0.1mm, but in reality, such precision is difficult to maintain consistently. Choosing a reputable, high-quality laser cutter brand is vital for ensuring long-term performance.
Conclusion
To maximize the benefits of high-power fiber laser cutting, operators must pay close attention to machine settings, maintenance, and proper handling. Investing in reliable equipment from trusted manufacturers will help avoid common pitfalls and ensure high-quality cutting results.
