China's bamboo and wood crafts have a long history. Bamboo and wood crafts refer to bamboo carvings, wood carvings, and decorative ornaments made of bamboo or wood. Bamboo and wooden handicrafts are not only decorative but also practical, such as bamboo curtains, wooden screens, and bamboo mats.
The commonly used materials are: mahogany, pine, fir, paulownia, rosewood, peach, and nanmu. Widely used in furniture, ornaments, models, root carvings, study rooms, utensils, screens, coat racks, etc.
Laser engraving of bamboo and wooden crafts refers to the use of numerical control technology as the basis and laser as the processing medium. The bamboo wood material is melted and vaporized physically under the laser irradiation to achieve the purpose of processing, so as to carve characters or patterns on bamboo products and wood products. Because laser technology is non-contact thermal processing, the contact surface is small, the loss is small, it is easy to operate, and the computer maps, so the processing effect is exquisite and delicate, which can meet the high-quality personalized processing needs, so it is widely used in bamboo and wood crafts processing.
Laser cutting of bamboo and wooden crafts is achieved by applying high power density energy generated after laser focusing. Under the control of the computer, the laser is discharged by pulses, thereby outputting a controlled repetitive high-frequency pulsed laser beam, forming a beam of a certain frequency and a certain pulse width. The pulsed laser beam is transmitted and reflected through the optical path and focused by the focusing lens group. On the surface of the processed object, fine, high-energy-density light spots are formed, and the focal spot is located near the surface to be processed, melting or vaporizing the material to be processed at an instant high temperature. Every high-energy laser pulse instantly sputters a small hole on the surface of the object. Under the control of the computer, the laser processing head and the material to be processed are continuously moved relative to each other according to a pre-drawn pattern. This will process the object into The desired shape.
Compared with traditional cutting processes such as oxyacetylene and plasma, the laser cutting speed is fast, the slit is narrow, the heat-affected zone is small, the edge of the slit is perpendicular, and the edge is smooth. At the same time, there are many types of materials that can be laser cut, including carbon steel , Stainless steel, alloy steel, wood, plastic, rubber, cloth, composite materials, etc.
