1： What is the principle of small laser engraving machine?

Laser is a kind of light. Like other luminaries in nature, it is produced by the transition of atoms (molecules or ions) and caused by spontaneous emission. Although laser is very light, it is very different from ordinary light. At first, laser only depends on short-term spontaneous emission, and the subsequent process is completely determined by stimulated emission. Therefore, the laser has very pure color, almost no divergence directivity and very high luminous intensity.

At the same time, laser has high coherence, high intensity and high directivity. After the laser is generated, it is transmitted by the reflector and irradiated on the processed product through the focusing lens, so that the processed product (surface) is subjected to strong heat energy, and the temperature rises sharply, so that the point is quickly melted or evaporated due to high temperature, which is matched with the laser head. The running track achieves the purpose of processing.

2： How to carve patterns with a small laser engraving machine

1. First, you need to prepare a tag file, a vector file in DXF or PLT format, or a file in picture format.

2. Then turn on the laser engraving machine, put the materials to be marked, and adjust the position of the red light until the red light converges to a point. (if there is no red light location, you can check the continuous marking on the software, and then adjust the focal length until you see the strong light, which is the best distance)

3. We can continue to work where we want to carve the pattern, and then we can carve the pattern we want on the selected item.

3： Precautions for operation of small laser engraving machine

1. When the laser engraving machine is working, it is forbidden to touch it with hands.

2. Turn on the smoke exhaust and blowing equipment during processing.

3. When carving wood and paper, we must pay attention to the processing speed to avoid fire.

4. The initial user should first locate the red light when carrying out irregular processing.

5. When processing thin plates and volatile materials, adjust the luffing level to less than 1mm.
