  After the laser cutting machine is installed, it can't be put into use immediately. It also needs to do a good job of relevant test run and adjustment. Because many people are in a hurry to put into use after installation, the accuracy of the cutting machine equipment is not adjusted well, resulting in cutting failure and poor phenomenon. So here's how to adjust the accuracy of the device.

  1. When the focus laser spot is adjusted to a small size, the initial effect is determined by the point sample, and the focal length is determined by the size of the point effect. We just need to find a very small laser point, and then this position is better. Process the focal length to start machining.

  2. In the front debugging of the cutting machine, we can use some test paper, workpiece scrap point to determine the precision of the focal length 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 appropriate position of the laser head.

  3. After installing the laser cutting machine, a marking device is installed on the cutting nozzle of the cutting machine. The marking device draws a simulated cutting pattern, which is a square of 1 meter. A circle with a diameter of 1m is built in, and four corners are drawn diagonally. After the stroke is completed, measure with a measuring tool. Whether the circle is tangent to the four sides of the square, whether the length of the square diagonal is √ 2 (the data obtained by opening the root is about 1.41M),

  The central axis of a circle should be divided equally into square sides and central points. The distance from the intersection of the axis and both sides of the square to the intersection of both sides of the square shall be 0.5m. By testing the distance between the diagonal and the intersection, the cutting accuracy of the equipment can be determined. Therefore, no matter after the laser cutting machine is installed, or before each start-up and use, it is necessary to do a detailed inspection work and adjust its accuracy, which can not only better guarantee the following operation of the cutting machine equipment more stable and accurate, but also effectively reduce the incidence of equipment failure.
