Application of Laser Technology in Wood Processing

Laser processing is one of the non-contact advanced processing technologies based on thermal energy. It has the advantages of fast processing speed, small material deformation, low processing noise, small cutting seam, high efficiency and high precision, which is conducive to the realization of digital processing. Therefore, it has been called "the universal machining tool of the 21st century" in various engineering material processing fields. At present, laser processing has been widely studied and applied in the fields of metal, ceramics, plastic products and wood processing. Domestic wood resources are relatively scarce, especially precious wood resources. Facing the growing demand for wood, how to improve the comprehensive utilization rate of wood and increase the added value of products has become an important issue in wood processing and manufacturing. The use of advanced laser processing and manufacturing technology can increase the output of processed products, and improve the surface adhesion and finishing performance after processing, which is of great significance to alleviate the contradiction between the supply and demand of wood resources and the growth of demand, and improve the quality of processed products.

So what are the main applications of laser technology in wood processing?

1. Wood laser cutting

Laser cutting is widely used in laser processing technology. It has fast speed, high refinement and adaptability, fine kerf, small heat-affected zone, and automatic control during the cutting process. The laser cutting technology adopts non-contact processing, which can minimize the processing deformation, will not cause cracks in the wood board, and reduce material waste; and the laser processing speed is fast, the precision is high, and the incision is smooth, and generally does not require subsequent processing. These are incomparable with traditional cutting methods. Relatively speaking, the cost performance of wood board laser cutting machine is still very high.

2. Wood laser engraving

Laser engraving of wood materials is a very potential surface decoration technology of wood, an important technical means to provide value-added wood surface. Wood laser engraving is mainly a high-power laser irradiating the surface of wood products, converting light energy into heat energy, and generating cracking and carbonization through instantaneous heat flow. In this way, the surface of local wood materials is eliminated, and the patterns and characters of the pattern engraving provided by the software are formed.

Nowadays, many people are using home-type desktop laser engraver . Its size is different from traditional laser engraving machines. It is very small, but it can do amazing work. We recommend a sculpfun brand sculpfun s10 laser engraving machine. It is equipped with a high-speed air auxiliary nozzle. When matched with an air compressor of 30L/min and 0.03Mpa, the S10 nozzle will eject a high-speed airflow of up to 14.5m/s. This will greatly improve the cutting penetration and cutting efficiency, and the ultra-thin and high-density 10W laser beam shaping technology is adopted, which means that the S10 has high energy density, strong cutting penetration and engraving capabilities.It can use for laser engraving and laser cutting.For the specific information of the product, you can browse the HTPOW website for details, which is the largest laser engraving machine agent in the world, and it will not disappoint you.

3. Laser heat treatment

Laser heat treatment of wood surface is one of the methods of wood modification. At present, on the market, mainly by laser heat radiation effect, the surface of wood is treated to change the physical and chemical changes of its internal properties and appearance. At present, laser heat treatment can be mainly used to improve the surface color and surface wettability of wood, increase the performance of surface coating materials and the new energy of anti-corrosion and mildew resistance.

4.laser marking

Early laser processing has been widely used in cutting and welding processes. Due to the pulse width from nanosecond to femtosecond laser sources, in recent years, it has been applied to other mechanical processing such as marking, marking, selective ablation and surface engraving of materials such as metals, ceramics, polymers and wood, etc principle of laser marking and laser engraving is the same, which is the use of high-power laser radiation to affect the surface of wood with marking images, text, etc.
