The technical method of laser engraving machine
engraving wood material - gray expression. Ordinary mechanical engraving can't carve different thickness points in an economic way, so it doesn't have gray expression. Laser engraving machine
is to achieve engraving by dot, which has natural advantages in gray performance. For this reason, we try to use the form of gray expression in the carving design. On the one hand, it reduces the coloring process and saves the cost; On the other hand, it enriches the expression means of carving and increases the level of graphics.
When the user is using it, first fill different gray levels in the graph (the text should be transformed into the graph first), and select black and white mode for carving output. You can try the effect of different dots, and the accuracy is generally not more than 500dpi. Carving material log (raw wood) wood is the most commonly used laser processing material so far, which is easy to carve and cut. Light colored wood such as birch, cherry or maple is easily vaporized by laser, so it is more suitable for carving. Each kind of wood sign has its own characteristics. Some are denser, such as hardwood. When carving or cutting, more laser power is needed. We suggest that before carving unfamiliar wood, we should first study the carving characteristics. Plywood carving on plywood is not much different from carving on wood, but there is a point to note that the carving depth should not be too deep. The edge of the cut plywood will be as black as the wood. The key is to see what kind of wood plywood is made of. Wood carving generally speaking, the carving on wood is usually Yin carving, and the depth of carving is generally deep. In this way, the power is generally set higher. If the wood is hard, the color of the carved figure may become darker. If you want to make the color lighter, you can improve the carving speed and try carving
Some wood in carving will produce some fumes attached to the surface of the wood. If the wood has been painted, it can be carefully wiped off with a wet cloth. If it is not painted, it may not be cleaned, causing the surface of the finished product to be stained. Wood cutting laser engraving machine
cutting depth of wood is generally not deep, the maximum cutting depth depends on the wood material and laser power, if you want to cut very thick wood, you can slow down the cutting speed, but may cause wood combustion. The specific operation can try to use large size lens, and use the method of repeated cutting.
Colored wood usually has a burning feeling after carving. It has a primitive artistic beauty when matched with the wood background color. The depth of the color mainly depends on the laser power and carving speed. But some wood is usually softer, and you can't change its color anyway (birch, for example). For the coloring of the finished product, the acrylic pigment can be used.
