In my experience with metal fabrication, I have often encountered challenges when it comes to cutting round holes. The analysis of these problems reveals various factors affecting accuracy and efficiency. From tool selection to machine settings, each aspect plays a crucial role. Through my exploration, I aim to provide effective solutions that address common issues in the cutting process. By understanding the intricacies involved, we can enhance our techniques and achieve precision in creating round holes, ultimately improving our overall productivity in hydraulic and mechanical applications.

Laserschneiden is an important process in the production of sheet metal. It is often found that the round hole is not round enough when cutting. How to solve it?

Problems and Solutions in Cutting Round Holes

1. The cutting speed and the blowing air pressure settings do not match.

During the cutting process, when the air pressure is too small and the cutting speed is too fast, edge scraping and the charring phenomenon will occur; when the pressure is too high, the speed is too fast, and the hole is easy to be blasted or the cutting size is small. Therefore, this requires the laser operator and the machine to work perfectly together. With experience, choose the appropriate speed and air pressure to make the cut hole more full.

Laser operators should work closely with the machine to adjust settings based on experience. Finding the right balance between cutting speed and air pressure is essential for achieving a clean, full cut.

2. The round hole is too small.

The best solution for laser cutting machine to cut round holes is that the ratio of plate thickness to the round hole is greater than 1:1. Of course, the larger the hole diameter, the easier it is to cut high-quality round holes. Otherwise, when the energy of the fiber laser cutting machine is insufficient, the cutting small holes are prone to breakpoints and the round holes are not round.

Ensure that the laser cutting machine is adequately powered for the size of the holes being cut. If small holes are consistently problematic, consider adjusting the design to accommodate larger diameters.

3. The servo motor parameters are incorrect.

Sometimes there will be ellipse or irregularity in the round hole. This is related to the X and Y axis motion mismatch. The direct cause of the X and Y axis motion mismatch is that the servo motor parameter adjustment is not suitable. Therefore, the quality of the circular hole is cut, and there are certain requirements for the servo motor.

Regularly check and calibrate servo motor parameters to ensure proper synchronization between the axes. This will help maintain the quality of the circular holes being cut.

4. Lead and lead screw accuracy errors.

If the servo motor parameter error affects the cutting quality, the accuracy error of the guide rail and the lead screw will directly lead to the accuracy of the round hole not expected. This is related to the strength of laser cutting machine manufacturers.

All of these parameters are used to identify whether the accuracy, speed, etc. of the cutting circular hole meets the standard requirements, and it is sufficient to determine whether the quality of the purchased laser cutting machine is passed. Therefore, in the process of buying a laser cutting machine, you must widen your eyes. It is very necessary to choose high quality and choose a big brand laser cutting machine!

Assess the quality and specifications of the laser cutting machine before purchase. High-quality machines from reputable manufacturers will typically have better accuracy and reliability.
