  • Method of repeatedly processing metal
    Patent number: 11478841
    Abstract: A method of processing hexahedral metal includes an X-axis edge forging step to press two X-axis edges on opposite sides to each other from a center of the hexahedral metal among edges formed in an X-axis direction, process the hexahedral metal into hexagonal prismatic metal, and restore the hexagonal prismatic metal to hexahedral metal, a Y-axis edge forging step to press two Y-axis edges on opposite sides to each other from the center of the hexahedral metal among edges formed in a Y-axis direction, process the hexahedral metal into hexagonal prismatic metal, and restore the hexagonal prismatic metal to hexahedral metal, and a Z-axis edge forging step to press two Z-axis edges on opposite sides to each other from the center of the hexahedral metal among edges formed in a Z-axis direction, process the hexahedral metal into hexagonal prismatic metal, and restore the hexagonal prismatic metal to hexahedral metal.
