Metallic brush craft is a metal working process. Under the action of an external force, the metal is forced through the mold, and the cross-sectional area of the metal is compressed to obtain a cross-sectional area shape and size, so that it changes shape. A tool of size is called a wire drawing die. For example, in the cable industry, the 8mm copper rod is made of a copper large drawing machine, and the copper rod is drawn into a copper wire through a set of (5~8) drawing molds from large to small, such as 3.5mm, 2.0mm, and the like. Machining surface treatment: Wire drawing is a method in which the wire is reciprocated by drawing, and the surface of the work piece is rubbed back and forth to improve the surface smoothness of the work piece. The texture of the surface is linear. It can improve the surface quality and cover the surface with slight scratches.
