Laser Engraver processing is based on numerical control technology and laser as the processing medium. The physical melting of the processed material under laser irradiation and the physical degeneration of the gas instantly achieve the purpose of processing. With the rapid development of optoelectronic technology, the application of laser engraving technology is becoming more and more extensive, and the requirements for engraving accuracy are getting higher and higher. The four most fundamental factors affecting laser engraving are: engraving speed, laser power, engraving accuracy, and materials. To achieve a certain engraving effect on a specific material, it is required to absorb a laser with a certain energy. This energy should be regarded as the laser energy absorbed by the material = laser power / engraving speed. To put it simply, to increase the laser energy absorbed by the material, you should increase the laser power or reduce the engraving speed. As to which method to use in the end depends on the material and the final engraving effect. Generally speaking, users avoid high and low speeds, because that will reduce production efficiency. In fact, it is not only the engraving speed that affects the engraving efficiency, but the engraving accuracy also has a great influence on it.
EngLaser Engraver is very fast, usually expressed in IPS (inches per second). High speed brings high productivity. Speed is also used to control the depth of the cut. For a specific laser intensity, the slower the speed, the greater the depth of the cut or engraving. Of course, you can also use the engraving machine panel to adjust the speed, or you can use the computer’s print driver to adjust. In the range of 1% to 100%, the adjustment is 1%.
For a specific engraving speed, the greater the intensity, the greater the depth of cutting or engraving. The intensity can be adjusted using the panel of the engraving machine, or it can be adjusted using the print driver of the computer. In the range of 1% to 100%, the adjustment is 1%. The greater the intensity, the greater the speed. The depth of the cut is also deeper.
The chirped laser beam spot size can be adjusted using lenses with different focal lengths. Small spot lenses are used for high-resolution engraving. A large spot lens is used for lower resolution engraving, but it is the best choice for vector cutting. The new equipment comes standard with a 2.0-inch lens. Its spot size is in the middle, which is suitable for various occasions.
Wood is by far the most commonly used Laser Engraver processing material and is easy to carve and cut. Light-colored wood like birch, cherry or maple can be laser gasified well and is therefore more suitable for carving. Each kind of wood has its own characteristics, and some are denser, such as hardwood, which requires greater laser power when carving or cutting. Laser engraving machines generally do not cut wood to a depth of less than 5mm. This is because the power of the laser is relatively small. If the cutting speed is slow, the wood will burn. After wood carving, there will generally be a feeling of being burned, and it has a primitive artistic beauty to match the wooden background. The depth of the color mainly depends on the laser power and carving speed.
Some time ago, IT men turned waste optical drives into laser engraving machines. It can be seen that the cost of laser engraving is not very high. Laser engraving wood is the most common laser teaching material. Wooden laser keyboards are environmentally friendly and suitable for low cost. It is worth experiencing.
