First of all, laser engraving technology uses high-density lasers to focus on the objects that need to be engraved. Because the laser itself has the advantages of small divergence angle and large energy density, it is focused through high-tech focusing lenses and focused to the desired level through physical processing. On the carved objects, the focus temperature is as high as tens of thousands of degrees, which can completely melt, vaporize, and burn the objects that need to be carved. At the same time, the blowing nozzle blows away the melted and vaporized substances, so as to realize the non-contact cutting of the objects. .

　　To sum up, the process of laser engraving is a complex chemical process. During this process, some smoke or some unpleasant odors will be produced. These odors are produced by the object to be engraved. Therefore, carving different materials will produce different smells. This is a big difference from the traditional mechanical engraving machine, which uses the spindle motor

　　The contact engraving that drives the knife, the engraving process is a physical process, and flying debris and dust will be generated during the engraving process without irritating odors.

　　The unpleasant smell produced by the laser engraving machine can not be avoided when it is working, but how to improve the working environment of the equipment operator?

　　In the early days of laser engraving machines, these odors may permeate the workshop. With the continuous improvement of the details of the products by the laser engraving machine manufacturers, the current laser engraving machines are equipped with a fan exhaust system, which can exhaust most of the unpleasant odors generated by the laser engraving machine when it is working. Workshop, thereby providing workers with an environmentally friendly working environment. Since the exhaust system is not the core component of the laser engraving machine, adding the exhaust system not only does not significantly increase the cost of the laser engraving machine, but the price of the laser engraving machine continues to drop due to socialized mass production.
