How to adjust the accuracy of laser cutting machine

The frequency of use of laser cutting machines in cutting companies is very high. Due to the long use time, the equipment will inevitably have accuracy deviations. This is also a problem that many consumers are more troubled by. For this, let's talk about how to adjust the accuracy of the equipment. .

1. When the spot of the focused laser is adjusted to be smaller, the initial effect is determined by spotting, and the focal length is determined by the size of the spot effect. We only need to find the small laser spot, and then this position is better. Process the focal length to start processing work.

2. Debugging at the front of the cutting machine, we can use some debugging paper, the scrap point of the workpiece to determine the accuracy of the focal position of the laser cutting machine, move the position of the height of the upper and lower laser heads, the size of the laser point will have different size changes when shooting. Adjust the position several times to find the smaller spot position to determine the focal length and suitable position of the laser head.

3. After installing the laser cutting machine, install a scribing device on the cutting nozzle of the CNC cutting machine, and the scribing device draws a simulated cutting pattern, which is a 1 meter square. A circle with a diameter of 1m is built in, and four corners are drawn diagonally. After the stroke is completed, measure it with a measuring tool. Is the circle 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 is approximately: 1.41m), the central axis of the circle should be equally divided into the sides of the square and the point in the center. The distance between the intersection of the axis and the two sides of the square to the intersection of the two sides of the square should be 0.5m. By testing the distance between the diagonal and the intersection, the cutting accuracy of the equipment can be judged.

The above is about the method of adjusting the precision of the cutting machine. Due to the high precision of the machine, after using the laser cutting machine for a period of time, the cutting precision will inevitably deviate. This error is usually caused by a change in focal length. Therefore, mastering how to adjust the accuracy is the basic knowledge of operating a laser cutting machine.
