As the laser focuses energy to melt the wood, blackening occurs during the cutting process. The cut edge is carbonized.

The first thing to note is that if you cut relatively thick wood, it is difficult to black out. We may all know that to avoid the carbonization effect of laser cutting, it is right to use high speed and low power, but some are misunderstood. They feel that the faster the better, the lower the power the better. In order to reduce blackening, cut it with fast, low power multiple times. This is very bad and the carbonization effect may be darker than normal.

Our low power and fastness must ensure that wood can be cut through at one time. The faster the better, the better the power, the lower the power, the better. The speed and power are determined according to the thickness of the board. When the power is reduced and multiple cutting is required, carbonization is actually more serious. Because the already-cut part is burned twice, the more carbon the cut, the more severe it becomes.

The first time it was cut through, it was burned once again during the second cut. The other part is not so dark because it was not cut through for the first time.

Therefore, the first point to note is to ensure that in a molding process, do not secondary processing, to avoid secondary damage.

Of course, in addition to the impact of power speed on the blackness, there is also a very important factor is blowing, cutting wood must strengthen the airflow, it is best to use a high-power air compressor, the machine must install a water separator, in order to protect the focusing mirror, Another factor for blackening and yellowing is that the gases produced by the cutting are blackened, and the blowing can assist cutting to make cutting easier and prevent ignition.


Key points: In the case of a one-shot cut-through, fast, low power, and air-assisted blowing is used.
