Matters needing attention when cutting round holes with fiber laser cutting machine

In recent years, with the rapid development of laser cutting machines, more and more customers have begun to use fiber laser cutting machines to cut round holes. Fiber laser cutting machine not only cuts a smooth section, but also has a variable aperture and flexible processing. It is the choice for cutting round holes.

However, using a laser machine to cut round holes is not as simple as imagined. Now, we will provide you with a simple analysis of the precautions for cutting round holes.

1. The round hole is too small.

Laser cutting machine is the best way to cut 1:1 holes. The larger the aperture, the better the cut. When the capacity of the laser cutting machine is insufficient, irregular round holes and residual breakpoints will be produced.

2. Gas pressure is too high or too low

If the gas pressure is too high, this hole will be larger than we need. If the pressure is too small, the cutting edge will become rough and burning will be severe. Therefore, choosing the right air pressure is one of the ways to solve the irregularity of circular hole cutting.

3. Servo motor parameters

Many parameters of the servo motor are related to the arc movement, and improper parameters will lead to the oval or irregular shape of the cutting hole.

4. The precision of the lead screw or guide rail is not enough

In some small factories, the technical strength and working ability of the workers are not high, the accuracy of the laser cutting machine is less than 0.1 mm, and the accuracy of cutting round holes cannot meet the requirements.

In short, we suggest to determine whether the quality of the laser cutting machine should be cleared, cutting accuracy, cutting speed and other parameters by observing the situation of laser cutting round holes, so as to determine the quality of the laser cutting machine.
