How to debug the accuracy of laser cutting machine

After the light cutting machine is used for a period of time, the cutting accuracy will have a certain error, which is often caused by the change of focal length.
Therefore, mastering how to debug accuracy is an essential knowledge of operation Laser Cutting machine

1. Focus laser light point is tuned to the minimum, shots to establish the initial effect, through the size of the spot effect to determine the focal length, we just recognize the laser light point to the minimum, then this position is the best processing focal length, and then start processing work.

2. In the front part of the laser cutting machine debugging, we can use some debugging paper, workpiece scrap to shots determine the accuracy of the focal length position, move the position of the upper and lower laser head height, laser spot size shots will have different size changes.
Multiple adjustments have been made at different positions to find the smallest position of the light point to determine the focal length and the optimal position of the laser head.

3. After the installation of the laser cutter, a dash device will be installed in the cutting nozzle of the CNC cutting machine, and an analog cutting graphic can be drawn by a dash device to simulate a square with a figure of 1m. Built-in a round with a diameter of 1m, the four corners are diagonally crossed, and after the stroke, the measuring tool is used to measure whether the rounded circle is tangent to the four sides of the square. Whether the diagonal length of the square is √2 (the data obtained by the opening root number is about: 1.41m), the axis of the circle should be divided equally between the square edges, and the point between the central axis and the square two sides intersecting points to the intersection of the square on both sides should be 0.5m. By testing the distance between the diagonal and the intersection, you can determine the cutting accuracy of the device.
