How to adjust the cutting effect of fiber laser cutting machine

Published on: September 29, 2020 Guangtiandi CNC

Fiber laser cutting machine with its irreplaceable processing advantages, has been the trust of many processing and manufacturing enterprises. Although the efficiency of laser cutting machine is not high, we still know how to adjust the fiber cutting machine. Let's learn about how to adjust the cutting effect of fiber laser cutting machine.



1. In the first half of debugging the fiber laser cutting machine, we can use some test paper and workpiece waste to spot to determine the accuracy of the focal length position. When moving the height of the upper and lower laser heads, the laser spot size will have different size changes. Adjust different positions several times, find out the smallest light spot position to determine the focal length and the best position of the laser head.


2. When the light spot of the laser focus is adjusted to the minimum, the initial effect is established by the spot effect, and the focal length position is determined by the size of the spot effect. As long as we recognize that the light spot of the laser reaches the minimum, then this position is the best processing focal length, and then start the laser cutting work.


3. After the installation of the fiber laser cutting machine, a scribing device will be installed on the nozzle of the machine equipment, and a simulated cutting pattern will be drawn through the scribing device, and the simulated figure is a square of 1m. A circle with a diameter of 1 m is built in. The four corners are diagonally drawn. After drawing, measure whether the circle drawn is tangent to the four sides of the square with measuring tools. If the diagonal length of the square is √ 2 (the data obtained by the root sign is about 1.41M), the central axis of the circle should bisect the sides of the square, and the distance from the point where the central axis intersects the two sides of the square to the intersection point of the two sides of the square should be 0.5m. The cutting accuracy of the equipment can be judged by testing the distance between the diagonal line and the intersection point.
