Precautions for green laser beam High stability cutting round holes

Sheet metal punching is generally made by punching, but with the disadvantages of low precision and many burrs, punch punching is gradually eliminated. With the continuous development of laser cutting machines, more and more companies have begun to use laser to cut round holes. Not only the cutting section is smooth, but the aperture can be changed at any time, and the processing flexibility is very high.

Laser cut round hole

However, laser cutting of circular holes is not as simple as everyone imagined. Irregular cutting of circular holes and insufficient verticality also happen from time to time. Therefore, the following is the problem of cutting round holes to analyze the reasons and precautions for everyone.

1 round hole is too small

Laser equipment cutting 1:1 holes is the best solution. The larger the diameter, the better the cutting. When the laser cutting machine with insufficient capacity cuts small holes, there will be irregular round holes and too many broken points.

2 The gas pressure is too large or too small

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 burning will be serious. Choosing the right gas pressure is one of the reasons to solve the irregular cutting of round holes.

3 Servo motor parameters

Many parameters of the servo motor are related to arc motion. If the parameters are not appropriate, the mismatch of x and y axis motions will cause ellipse or irregular graphics in the cut circular hole.

4 Lead screw or guide rail accuracy is not enough

Some small factories have low technical strength and low level of workers, and the precision of the laser cutting machine produced cannot reach 0.1mm, so the precision of the circular hole cut does not meet the requirements.

Therefore, it is recommended to identify the quality of the laser cutting machine by observing the laser cutting round holes to identify whether the quality of the laser cutting machine to be purchased is satisfactory. Whether the cutting precision, speed and other parameters meet the standard.
