Points to note when debugging the accuracy of fiber laser cutting machine

The wide application of fiber laser cutting machine has greatly improved the production efficiency of certain occupations. However, in the operation process, the operators often do not have a good grasp of the cutting accuracy and cannot perfectly display the laser cutting. Then we have to debug the fiber The following points need to be paid attention to when the accuracy of the laser cutting machine.

1. When the spot of the focus laser is adjusted to a very small time, it is very early to set up a spot shot. The focal position is judged by the size of the spot. When the spot of the laser is at a very small time, then this position is Good processing focal length, and then start processing work.

2. In the first part of the laser cutting start-up and debugging, we can use some workpiece tails and scraps to determine the accuracy of the focal length orientation. When moving the upper and lower laser head height orientations, the laser spot size will be different when it is shot. Change. Repeated adjustments in different orientations to find out the orientation of a particularly small spot to determine the focal length and the optimum orientation of the laser head.

3. After the laser cutting machine is completed, a scribing device can be installed on the cutting nozzle of the CNC cutting machine, and then a scribing device can be used to draw an imitating cutting pattern, such as a 1m square. A circle with a diameter of 1m is built-in, and the four corners are drawn diagonally. After drawing, use a measuring tool to measure whether the drawn circle is tangent to the four sides of the square. Whether the diagonal length of the square is √2, which is about 1.41. The central axis of the circle should bisect the sides of the square, that is, the distance from the point where the central axis intersects the two sides of the square to the intersection of the two sides of the square should be 0.5m. Test the interval between the diagonal and the intersection point to determine the cutting accuracy of the equipment.
