Why the round hole of laser cutting machine is not round

  Laser cutting machine is the laser that will be emitted from the laser. The function of this laser is very good. We can see that there are many functions of laser cutting machine in the industrial field. The round holes in laser cutting machine are relatively round, but they are always out of round. So, why does the round hole of laser cutting machine appear out of round?

  Sheet metal processing can hardly do without the drilling procedure. At present, most of sheet metal processing fields have begun to use laser cutting machine to process circular holes. It is feasible to use laser cutting machine to process circular holes, but we need to pay attention to the methods and skills. We can know from repeated tests that there are many factors bothering our processors. To cut standard parts, we need to pay some small fees Mind, otherwise it can't be completed. The main problems are as follows.

  1. Unsuitable air pressure

  We all know that when cutting stainless steel, carbon steel and other metal materials, we need to use gas, such as nitrogen, oxygen and so on. Gas will have a great impact on our cutting quality. If the air pressure is too small, there will be slag scraping and carbonization on the edge, and if the air pressure is too large, there will be a hole explosion. So choose a suitable round hole, can better cut round hole.

  2. Too small round hole

  We have obtained many experiments that the proportional aperture of the circular hole cut by laser cutting machine: the thickness of the plate is 1:1 as the basic proportion, the larger the aperture, the easier it is to produce full and smooth circular holes, on the contrary, the difficulty is increased geometrically. In other words, the larger the aperture, the easier it is to produce a high-quality round hole.

  3. Servo motor parameters are wrong

  It's not difficult to find out when cutting round holes. Sometimes there will be out of round situations, including ellipse and edge angle. In this case, in addition to laser attenuation, it's more likely that the motion axis doesn't match. Check the parameters of the motor. If you want to make a good round hole, the requirements for the motor are relatively large. Servo motors are generally recommended.

  4. Precision error of guide rail and lead screw

  The error of servo motor will affect the cutting quality, and the same guide rail and lead screw will also affect the accuracy of laser cutting round holes, which is not up to expectations. This is also related to the strength of the laser cutting machine manufacturers. Some factories will be greasy about the important components of these equipment if they cheat. Once the accuracy is not reached, the effect of round holes will be poor. Therefore, the laser cutting machine manufacturers should be careful to choose.

  The above is the basic reason why the round hole of laser cutting machine is out of round shape. You can simply understand it. I believe that you can know the reason from these summaries.
