The fiber laser cutting machine is a laser emitted from a laser. The effects of this laser are very good. In the industrial field, it can be seen that the laser cutting machine has many functions. The round holes in the laser cutting machine are relatively round, but there will always be out-of-round phenomena. So, why is the round hole of the laser cutting machine not round?
Sheet metal processing is basically indispensable for punching procedures. At present, most of the sheet metal processing fields have begun to use laser cutting machines. It is feasible to use laser cutting machines to process round holes, but it is necessary to pay attention to methods and techniques. It can be known from repeated tests that there are many factors that trouble our processors. To cut out standard parts, we need to take some careful thoughts, otherwise we cannot complete them. The problems are mainly concentrated in the following aspects.
1. Air pressure is not suitable
We all know that when cutting metal materials such as stainless steel and carbon steel, gas is used, such as nitrogen, oxygen, etc. Gas will have a great impact on our cutting quality. If the air pressure is too low, scraping and charring will often occur on the edges, and bursting will occur when the gas pressure is too high. Therefore, selecting a suitable circular hole can better cut the circular hole.
2. The round hole is too small
We have obtained many experiments, the ratio of the hole diameter of the fiber laser cutting machine to cut round holes: the thickness of the plate is 1: 1 as the base ratio. The larger the hole diameter, the easier it is to produce full and smooth round holes. On the contrary, the difficulty increases geometrically. That is, the larger the hole diameter, the easier it is to produce high-quality circular holes.
3. Incorrect servo motor parameters
It is not difficult to find when doing round hole cutting, and sometimes there are cases of out-of-round, including ellipses and corners. In this case, in addition to the case of laser attenuation, it is more likely that the motion axis motion does not match. For the parameters of the motor, to make a good round hole, the requirements for the motor are also relatively large. Servo motors are usually recommended.
4.Accuracy error of guide rail and lead screw
The error of the servo motor will affect the cutting quality. Similarly, the guide rail and lead screw will also affect the accuracy of laser cutting round holes. This is also related to the strength of the fiber laser cutting machine manufacturer. Some factories will be tricky on the important components of these devices. Once the accuracy is not reached, the effect of round holes will be poor. Choose carefully.
The above is the basic reason for the non-roundness of the round hole of the fiber laser cutting machine. You can simply understand it. I believe that you can know the reason for the summary.
