The former sheet metal punching is usually made by punching machine. Although it is relatively convenient and fast, its low accuracy and many burrs can not meet the increasingly high demand for commodity quality, and the punching machine is slowly being eliminated. Now with the continuous development of laser cutting machines, more and more enterprises begin to use laser cutting machines to cut round holes. Not only is the cutting section smooth, but also the aperture can be changed at any time, and the processing flexibility is very high.
However, laser cutting of circular holes is not as simple as you think. Irregular cutting of circular holes and insufficient verticality also happen from time to time. So, let’s analyze the reasons and precautions for the problem of laser cutting machine cutting round holes.
Common problems and precautions of laser cutting machine cutting round hole
1. The round hole is too small
Laser equipment can cut 1:1 holes. The larger the hole diameter, the better the cutting. When the laser cutting machine with insufficient capacity cuts small holes, it will have irregular round holes and too many broken points.
2. Gas pressure is too high or too low
If the gas pressure is too high, the hole will burst. If the pressure is too low, the cutting edge will be rough and the edge burning will be serious. Choosing the appropriate gas pressure is one of the reasons to solve the irregular round hole cutting.
3. Servo motor parameters
Many parameters of the servo motor are related to arc motion. Improper parameters of the x and y axis motion mismatch will cause elliptical or irregular shapes in the cutting circular hole.
4. The accuracy of lead screw or guide rail is not enough
Some small factories have low technical strength and workers’ level, and the precision of the laser cutting machine produced is less than 0.1mm, so the precision of the round hole cut cannot meet the requirements.
Here is a tip to tell you. To identify the quality of the laser cutting machine, we can observe the condition of the laser cutting round hole to identify whether the quality of the laser cutting machine to be purchased is qualified, and whether the cutting accuracy, speed and other parameters meet the standard.
