To enhance efficiency in wood products processing, understanding the parameter settings for carbon dioxide laser marking machines is crucial. These machines offer precise image depiction and clear printing capabilities for logos and production dates on wood surfaces. Lack of knowledge in parameter settings can hinder optimal performance. Our detailed guide will assist your companies in mastering this technology, ensuring seamless operations for wood processing needs.
We must first understand that the working principle of the carbon dioxide laser marking machine. It uses harnessing high-energy laser beams to create lasting marks on wooden surfaces. Through a process that involves a high-temperature thermal effect, the laser beam initiates a carbonization reaction, resulting in resilient markings. This technique is widely preferred in the wood processing sector due to its ability to maintain the natural grain of the wood while introducing a distinctive visual aspect to the final product. The integration of laser marking in wood processing operations enhances efficiency and precision, ultimately leading to higher quality outputs.
However, to achieve this, setting parameters is crucial. Because under the influence of different wood properties, laser power, speed, frequency, focal length and other factors, the effect of laser marking will show huge differences. Therefore, before carbon dioxide laser marking, we need to fully consider the following aspects:
1. Laser Power Setting
Laser power is a key factor affecting the marking effect. Generally speaking, the greater the laser power, the more obvious the marking effect will be, but it will also speed up the carbonization of the wood, which may result in marks that are too deep or too wide. In actual operation, the laser power can be adjusted according to the hardness, thickness and marking requirements of the wood. It is recommended to start with low power and gradually adjust to the desired effect.
2. Laser Speed Setting
Laser speed directly affects the clarity and integrity of the mark. Too fast may result in unclear marks, too slow may result in marks that are too deep or too wide. The right laser speed should produce the desired color and depth of the mark on the wood surface. When setting the laser speed, you can adjust it according to the texture, hardness and other factors of the wood until you achieve a satisfactory effect.
3. Laser Frequency Setting
Laser frequency refers to the number of laser pulses produced by the laser per second. If the frequency is too high, the wood surface may overheat and the marking effect is poor; if the frequency is too low, the clarity of the marking may be affected. The appropriate laser frequency should produce good color and clarity of the mark. In actual operation, the appropriate frequency can be selected according to the laser model and wood characteristics.
4. Focal Length Setting
The laser focal length refers to the distance of the laser beam from the laser exit to the wood surface. A suitable focal length enables the laser beam to form clear marks on the wood surface. When setting the focal length, it can be adjusted according to the thickness, hardness and other factors of the wood to achieve the best marking effect.
5. Wood Types
(1)Log: When the wood is carved, it will show black lines. This is generally used for deep engraving. We can fill the file with the parameters of deep engraving, and change the filled line spacing to 0.03, so that the laser stays longer. , then change the speed to 500, then the power to 80, and the frequency to 20. In this way, wood carving can be carried out. If a fire occurs, the power can be changed to 50 or below.
(2)Painted wood: If you are using painted wood and need to engrave on the surface, you can change the parameters to a lower power, then change the filling line spacing to 0.06, and then change the speed to 800. During the beating process The paint surface can be removed very quickly without burning.
(3)Bakelite material: This material is a plastic structure material. Many chess materials use this kind. You can change its speed to 2000, the power to 85, the frequency to remain unchanged, and the filling to return. Fill the font and then engrave it. However, if the pleasant effect is not obvious, you can change it to 1500 or less.
Conclusion
The carbon dioxide laser marking machine uses different materials to mark wood. The results are different and require different parameters. If we want the effect to be good, beautiful and fast, we need to conduct multiple tests. This parameter does not It is not a fixed parameter. Different machine power usage effects are different, so the above parameters can only be used as a preliminary reference when using it.
