How to adjust the accuracy of laser cutting machine


xt Laser-laser cutting machine
The adjusted laser cutting machine has very high accuracy and is widely used in the cutting of metal materials. The precision of the metal laser cutting machine determines the cutting quality of the workpiece and the production efficiency of the enterprise. After the laser cutting machine is used for a period of time, the cutting accuracy will decline. There are certain errors, which are often caused by changes in focal length. It is extremely necessary to adjust the cutting accuracy in time. Therefore, mastering how to adjust the accuracy is an essential knowledge to operate the laser cutting machine. Let me popularize it for you.

During the whole production process of laser cutting machine, the requirements for accuracy are also very high, but many times you will find that the accuracy of the laser cutting machine you just bought or the whole equipment is not so accurate after a period of use. In this case, how to debug the laser from the current situation, the accuracy of the laser cutting machine in the process of debugging, we must look at the above focus, The light spot of the focus laser is often easily modulated to the minimum. In this case, we can set the initial effect and determine the position of a series of focal points by the size of the light spot effect. Of course, as long as we recognize that the light spot of the laser reaches the minimum, the other position is the best processing focal length. In this case, we can set the position of that place there, Then you can make such a device work.
In addition, in the adjustment of the first half of the laser cutting machine, you can also use some different props. For example, adjusting the focal length is often very important for debugging, and many accuracy can be grasped. At the same time, you can move the laser up and down, because only in this way can you have a certain control of the height, and the size of the laser spot will have various changes. Only after multiple adjustments can we find the most appropriate focus and then determine the relevant position.
In addition, after the laser cutting machine is installed, it is completely possible to slide lines on it, and then simulate the relevant cutting patterns.

Pay attention to the following points when debugging the accuracy of the laser cutting machine:

  1. When the spot of the focusing laser is adjusted to the minimum value, the initial effect is established through the spot shooting, and the focus position is determined by the size of the spot effect. We only need to confirm that the laser spot is at the minimum value, then this position is the best. Process the focal length, and then start processing.
  2. In the first part of the laser cutting machine debugging, we can use some test paper and workpiece waste to judge the accuracy of the focal length position by spotting, move the position of the upper and lower laser head height, and the laser spot size will change in different sizes during spotting. Adjust different positions several times to find out the minimum spot position, so as to determine the focal length and the best position of the laser head.
  3. After the laser cutting machine is installed, a scribing device will be installed on the cutting nozzle of the CNC cutting machine, and a simulated cutting pattern will be drawn through the scribing device. The simulated pattern is a 1 meter square. A circle with a diameter of 1 meter is built inside, and diagonal lines are drawn at four corners. After drawing, use a measuring tool to measure whether the drawn circle is tangent to the four sides of the square. No matter the diagonal length of the square is √ 2 (the data obtained by opening the square root is about 1.41m), the central axis of the circle should bisect both sides of the square, and the distance from the intersection of the central axis and the two sides of the square to the intersection of the two sides of the square should be 0.5m. The cutting accuracy of the equipment can be judged by detecting the distance between the diagonal and the intersection point.
