How to debug the precision of the laser cutting machine

How to debug the precision of the laser cutting machine. After the optical cutting machine is using for a period of time. The cutting accuracy will have a certain error, which is often causing  the change of the focal length.

Therefore, mastering how to debug accuracy is essential for operating laser cutting machines.

First, when the spot of the focus laser is adjusting to the minimum, the initial effect is establishing spotting.


And the focal length is determining 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 focal length is processing to start the machining work.

Secondly, in the front part of the laser cutting machine debugging.


We can use some debugging paper, workpiece scrap to point to determine the accuracy of the focal length position.

Moving the position of the upper and lower laser head height, the laser spot size will have different size changes when shooting.

Adjust the position multiple times to find the smallest spot position to determine the focal length and the optimal position of the laser head.

Thirdly, after the laser cutting machine is installing, a scribing device is installing on the cutting nozzle of the CNC cutting machine.


And a simulating cutting pattern drawn the scribing device. And the simulating  figure is a square of 1 m.

A circle with a diameter of 1m building in, and the four corners are diagonally drawing.

After the stroke finishing, the measuring tool using to measure whether the circle drawing  tangent to the four sides of the square.

Whether the length of the diagonal of the square is √2 (the data obtain 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, it can adjust the cutting accuracy of the device.
