Using laser to cut wood has the advantages of high precision, narrow slit, fast speed and smooth cutting surface. However, because the laser focused energy melts the wood, there will be blackening during the cutting process, that is, the cutting edge is carbonized.

To avoid the carbonization effect of laser cutting, it is right to use high speed, low power, but some are misunderstood. They feel that the faster the better, the lower the power the better, and to reduce blackening, they cut multiple times with fast speed and low power. This is very bad and the carbonation effect may be darker than normal.

Our low power and fast speed must ensure that the wood can be cut through at one time. The faster the speed is, the better the speed, and the lower the power, the better. If reducing the power requires multiple cuts, the carbonization phenomenon is actually more serious. Because the part that has been cut through will be burned a second time, the more you cut it, the more serious the carbonization will be.

Therefore, the first point to pay attention to is to ensure that it is formed in one processing, not secondary processing, to avoid secondary damage.

Of course, in addition to the influence of power speed on blackening, there is also a very important factor, that is, blowing air. When cutting wood, you must blow air strongly. It is best to use a high-power air compressor, because another factor for blackening and yellowing is that cutting wood The gas produced is blackened, and the blow can assist in cutting, making cutting easier and preventing fire.
