The invention discloses a machining technology for a shaving board. Brushwood serves as the raw material and is combined with waste wood shavings and sawdust, and the shaving board is machined through the processes of raw material chipping, wood shaving, drying, separating, glue mixing, molding, prepressing, hot pressing, post-processing (heat processing and constant humidity processing) and the like. Due to the process control of key steps, the product strength is high, toughness is strong, the surface of the board is fine and smooth, meanwhile, waste is used and changed into treasure, a large number of natural resources are saved, energy conservation and environment friendliness are achieved, cost is low, and market promotional value is huge.
