Many beds, tables, stools and other furniture in our daily life are made of solid wood, so we know that we first cut down the trees, and then the thick logs are cut into extremely thin veneers by large-scale special machines (such as rotary cutting). After sterilization, bleaching, drying and surface protection, they are sold to furniture factories for furniture surface decoration, such as surface veneering of large shift tables and wardrobe, Further surface oiling and other treatments are required; Or it can be further made into laminate to be used as furniture structural parts, such as backrest and seat plate of chair. After processing, such as sawing, modeling, splicing, bending, etc., it is made into the whole or components of solid wood furniture, such as armrest, chair foot, sofa armrest or seat frame of chair; In the exposed part of furniture, further surface treatment, such as painting, etc., is generally required. In fact, wood processing residues, such as sawdust, can also be used to make furniture, such as particleboard.
