High-precision fiber laser cutting machine is widely used in the cutting of metal materials, and the precision of fiber laser cutting machine determines the cutting quality and production efficiency of metal parts, any laser cutting machine in use for a period of time, there will be a certain accuracy error, this error is often caused by the change of focal length, it is necessary to adjust the focal length in time. So how to debug the accuracy is a very important technology in the use of laser cutting machine, let's take a look.

The laser cutting machine is a large project, and the components are also very fine during production, and the requirements for precision are also high. Many times after the laser cutting machine has been used for a period of time, suddenly the accuracy is not so accurate, then in this case, you need to observe the focus of the cutting part and the focal length adjustment is correct, the focus of the laser light is often easy to be adjusted into a particularly small, then in this case, and then the special initial relevant Settings, Through the size of the spot to determine a series of focus position, of course, as long as we identify the laser spot to reach a particularly small, then the other position is a particularly good processing focal length, in this case, we can set the location of the place there, and then you can let such a device start to work. In addition, in the first half of the laser cutting machine mode, you can also use some different props, such as debugging refers to the important focal length is often used for debugging, a lot of accuracy can be mastered, at the same time, you can also move the laser up and down, because only in this way can you have a certain control of the height, And the laser spot will have a variety of different changes, many times to adjust, in order to find a particularly suitable focus, and then to determine the relevant position.

The following points need to be noted when debugging the accuracy of the fiber laser cutting machine:

1.The focus of the laser spot is adjusted to a particularly small, the point of the establishment of the special beginning, through the size of the spot to judge the focal length, when the laser spot to a particularly small, then this position is a good processing focal length, and then begin processing work.

2. In the first part of the debugging of the laser cutting machine, we can use some workpiece tail and waste to determine 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. Adjust different positions many times to find a particularly small spot position to determine the focal length and the special best position of the laser head.

3. After the installation of the laser cutting machine, you can install a scribing device on the cutting mouth of the CNC cutting machine, and draw a simulated cutting pattern through the scribing device, such as a square with a simulated graph of 1m. A circle with a diameter of 1m is built in, and the four corners are drawn diagonally. After the circle is drawn, the measuring tool is used to measure whether the circle is tangent to the four sides of the square. 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 between the point where the central axis intersects the two sides of the square and the point where the two sides of the square intersect should be 0.5 m. Test the distance between the diagonal and the intersection point, you can judge the cutting accuracy of the equipment.
