This Week's Top Stories About Laser Cutting Wood
You must know laser cutting wood
The use of laser cutting wood has the advantages of high precision, narrow slit, fast speed, and smooth cutting surface. However, since the laser focusing energy melts the board, there is a blackening phenomenon during the cutting process, that is, the edge of the cutting is carbonized.
How to reduce or even avoid this situation. The first thing to note is that if you cut a thicker board, it is difficult to get black. Everyone knows that to avoid the carbonization effect of laser cutting, it is correct to use high speed and low power, but some are misunderstood. They think that the faster the better, the lower the power, the better, in order to reduce blackening,
Multiple cuts with fast, low power. This is very bad, the carbonization effect may be darker than normal.
Our low power and speed must be guaranteed to cut through the wood 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 plate. And if the power reduction requires multiple cuts,
In fact, the carbonization phenomenon is more serious. Because the part that has been cut through will be burned twice, the more the cut, the more serious the carbonization. The first cut through was burned once again during the second cut. The other part, because it was not cut through for the first time, was not so dark.
Therefore, the first thing to note is to ensure that in one processing, do not process twice, to avoid secondary damage.
The speed is fast and the power is contradictory. The faster the speed, the harder it is to cut through. The smaller the power, the harder it is to cut through. We have to prioritize between the two. Speed is much more important than low power. With a larger power, try the fastest cut-through speed.
Of course, in addition to the impact of power speed blackening, now, there is a very important factor, that is, blowing, cutting wood must strengthen the airflow, it is best to use high-power air compressor, the machine must be equipped with oil-water separator, in order to protect the focusing mirror Another factor that causes blackening and yellowing is that the gas produced by the cutting is blackened, and the blowing can assist the cutting to make cutting easier and prevent fire. If you find that it is black, it may be a material problem, and the glue content of the plywood will also affect. It is also very important to find suitable material.

Key points:
To ensure a one-time cut through, use fast, low power, and use the air compressor to assist in blowing.
