Fiber laser cutting machine precision debugging method

After the fiber laser cutting machine use for a period of time, the cutting accuracy is inaccurate due to the change of the focal length. How to deal with this situation? And fiber laser cutting machine precision debugging method.
Mastering how to debug accuracy is an essential knowledge for operating laser cutting machines. We are here to give you a generalization. Fiber laser cutting machine precision debugging method:

(1) When the spot of the focus laser adjust to the minimum, the initial effect of the spot shot establish.

And the focal length determine the size of the spot effect. We only need to look for the spot of the laser to the minimum, then this position is the best. The machining focal length, and then start the processing work.

(2) In the front part of the laser cutting machine debugging, we can use some debugging paper.

Then workpiece scrap to point to determine the accuracy of the focal length position. Then move the position of the upper and lower laser head height. And the laser spot size will have different size changes when shooting. So adjust the position multiple times to find the smallest spot position to determine the focal length and the optimal position of the laser head.

(3) After the installation of the fiber laser cutting machine. A scribing device install on the cutting nozzle of the numerical control cutting machine.

And a simulated cutting pattern draw the scribing device, and the simulated figure is a square of 1 m. A circle with a diameter of 1m is built in, and the four corners are diagonally drawn. After the stroke is finished, the measuring tool is used to measure whether the circle drawn is tangent to the four sides of the square.

Whether the length of the diagonal of the square is √2 (the data obtained by opening the root number is about: 1.41m), the central axis of the circle should be equally divided into the sides of the square, and the point where the central axis intersects the two sides of the square to the intersection of the two sides of the square The distance should be 0.5m. By testing the distance between the diagonal and the intersection, the cutting accuracy of the device can be judged. This is a real experience!
