Fiber laser cutting machine precision debugging method

Guide: After using the fiber laser cutting machine for a period of time. Due to the change in focal length, the cutting accuracy will incorrect. How to deal with this situation. And fiber laser cutting machine precision debugging method.

Mastering how to debug the precision is a necessary knowledge for operating the laser cutting machine. XT LASER is here today to popularize it. And the method for precision debugging of the fiber laser cutting machine:

(1) When the focal point of the focus laser is adjusted to the minimum. Then the spot effect is performed to establish the initial effect.

According to the size of the spot effect to determine the focal length. And we only need to identify the minimum point of the laser light. Then this position is the best processing focus, and then start processing.

(2) In the first part of the laser cutting machine debugging. And we can use some debugging paper and workpiece waste to spot-fire to determine the accuracy of the focal position.

Moving the position of the height of the upper and lower laser heads, the size of the laser spot will change with different sizes. Then adjust the different positions multiple times to find the smallest spot position to determine the focal length. And the optimal position of the laser head.

(3) After the fiber laser cutting machine install, a cutting device is installed on the cutting nozzle of the numerical control cutting machine. And a simulated cutting pattern drawn by the cutting device.

The simulated figure is a 1m square. And a circle with a diameter of 1m is built in. Then the four corners respectively diagonally drawn. After drawing, use a measuring tool to measure whether the drawn circle tangent to the four sides of the square. So is the diagonal length of the square √2 (the data obtaine by the opening number is about 1.41m). And the center axis of the circle should bisect the sides of the square. Then the point where the center axis intersects with the two sides of the square. The distance should be 0.5m. Test the distance between the diagonal and the intersection to determine the cutting accuracy of the device. This is a real experience!
