How to Solve the Problem of Coking Black in Laser Carver Processing Wood

The laser engraver processes wood in a special way, which is one of the thermal processes that can be used in the laser laser engraving machine "no ink engraving" on wood. The melting point of the wood is relatively low, leaving a black color mark, so that some of the laser engravers do not process graphic engraving patterns, but three-dimensional patterns. Carving surfaces can be difficult to avoid leaving a black mark, generally if such a situation occurs, you can try to solve with the following three methods:
To reduce the power of the laser engraver while maintaining the cutting effect, the reason why the laser heat is too high can also be used to reduce the scorch black mark.
After processing the laser engraver, the surface is carefully polished and a layer of carbonide is removed.
3. If you do not need to show in color, you can directly paint the solution.
