How to adjust the accuracy of fiber laser cutting machine

How to adjust the accuracy of fiber laser cutting machine?

1.When the spot of the focus laser is adjusted to the minimum, the initial effect is established by spot shooting, and the focal length is judged by the size of the spot effect. We only need to look for the minimum laser spot, then this position is the best processing focal length , And then start processing work.

2.In the first part of the laser cutting machine debugging, we can use some debugging paper and workpiece waste to spot the accuracy of the focal length position, move the position of the upper and lower laser head height, the laser spot size will have different size changes when spotted. Make adjustments to different positions several times to find the smallest spot position to determine the focal length and the best position of the laser head.

3.After the fiber 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, which is 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, the central axis of the circle should bisect the sides of the square, and the distance between the intersection of the central axis and the two sides of the square and the intersection of the two sides of the square should be 0.5m. Test the distance between the diagonal and the intersection point to determine the cutting accuracy of the equipment.
