The laser cutting machine has many advantages such as high precision, narrow slits, fast speed, and smooth cutting surface. However, because the energy collected by the laser beam can melt the wood, such a phenomenon also exists widely. It is possible for the cutting machine to cut black wood. This is the result of the carbonization of the wood. So how can we avoid this?

If it is said that it is cutting thin wood, it is easy to achieve a non-carbonized state through adjustment, but the board over 5mm must be treated according to the specific situation. The acrylic laser cutting machine manufacturers will explain the laser cutting machine in detail below. How to avoid blackening:

The normal way of thinking is high speed and low power. However, it is not better to limit the limit. In order to reduce blackening, many people will use low power to cut multiple times. Repeated operations will make carbonization more serious. Generally, one-time cutting is better. In the case of one-time cutting, high speed and low power are used. This is the correct idea. Avoiding secondary burning can also avoid the risk of carbonization.

However, the problem comes again. The pursuit of high speed and low power is contradictory in itself, which requires our operators to perform actual experiments with priority adjustments. The experience of Suzhou laser engraving machine is that high speed is more important than low power. Of course, you must go through the actual operation and choose the solution you think is good. In addition, if you want to cut wood with a relatively large thickness, it is recommended to increase the power of the air-jet equipment, because in addition to the blackness of the power and speed, air blowing is also a very important factor when cutting. When blowing air, you must blow air strongly. Use a high-power air compressor. Another reason for the blackening and yellowing is that the gas generated during cutting is blackened.

Of course, wood cutting is also a form of ordinary cutting by laser cutting machines. If none of the above can meet your requirements for wood cutting, then you may wish to try whether the machine itself has problems, such as uneven platforms, uneven wood, etc. The effect of focal length must be paid attention to, try not to use the limit value to cut, because the cut is not transparent.

When all of the above factors are eliminated and the methods have been tested, it is still black, then it may be a problem with the material itself, and the glue content of the plywood will also affect the blackness in cutting.

The main points in this section: Avoid the case where the laser cutting machine cuts the wood black, and in the case of cutting through once, try to use a combination of high speed, low power, and strong air blowing.
