This article will tell you how to operate the laser cutting machine for sheet metal drilling, mainly the analysis of the causes of some problems during drilling. Let’s have a look.
Sheet metal punching is a conventional operation, many of which were made by punching machines before, but it can be imagined that the accuracy of the punched holes is certainly not ideal, and there are some troublesome problems such as too many burrs on the edges. Now, with the advent of the laser cutting machine for sheet metal, the traditional punch punching form is gradually being eliminated, because most enterprises tend to use laser cutting machines to punch holes, The advantage is that not only the section is smooth and burr-free, but also the hole diameter can be modified at will. The flexibility of the later stage is never achieved by the stamping equipment.
However, although the advantages of sheet metal laser cutting machine are obvious, it is not without problems, such as irregular cutting round holes, insufficient perpendicularity and other problems also occur from time to time, but what we can overcome is how to operate the laser cutting machine sheet metal drilling? Let’s briefly talk about the common problems of laser cutting machine when cutting round holes. Let’s see~
1、 The hole diameter to be punched is too small
Laser equipment can cut 1:1 holes. The larger the hole diameter, the better the cutting. When cutting small holes, the laser cutting machine with insufficient capacity 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, and if the pressure is too low, the cutting edge will be not smooth, rough, and seriously burned. Therefore, it is critical to select the appropriate gas pressure, which is also a method to solve the irregular circular hole cutting.
3、 Servo motor parameters
Many parameters of servo motor are related to circular arc motion. Improper parameters of x and y axis motion mismatch will cause ellipse or irregular figure in cutting circular hole.
4、 The precision of the lead screw or guide rail of the sheet laser cutting machine is not good
The manufacturing level of some thin plate laser cutting machine enterprises is relatively low, which also makes the laser cutting machine accuracy less than 0.1mm, and also leads to the hole drilling accuracy can not meet the standard.
Therefore, if you want to see whether the quality of a laser cutting machine for thin plates can work, you can drill a few holes first, because drilling is a trivial matter, but it plays a very important role in identifying the quality of the laser cutting machine, which involves the cutting accuracy, cutting speed and other key parameters of the laser cutting machine for thin plates.
