Many beds, tables, chairs, and other furniture in our daily lives are made of solid wood. Therefore, we know that the first step is to cut down the trees, and then the thick round wood is cut into extremely thin wood veneer by large specialized machines (such as rotary cutting). After sterilization, bleaching, drying, surface protection, and other treatments, it is sold to furniture factories for furniture surface decoration, such as the surface veneer of large benches, wardrobes, etc., and further surface oiling and other treatments are required; Alternatively, it can be further made into laminated panels for use as furniture structural components, such as chair backrests, seat panels, etc. After processing, such as sawing, shaping, splicing, bending, etc., it is made into a whole or component of solid wood furniture, such as the armrests, legs, sofa armrests or seat frames of chairs; In the exposed part of furniture, further surface treatment such as spray painting is generally required. In fact, wood processing residues, such as sawdust, can also be used to make furniture, such as particleboard.
