A rounding machine is an industrial equipment used for bending and forming metal sheets, profiles, and other materials. It mainly applies external force to materials through multiple rotating rollers to cause plastic deformation, eventually forming circular, arc-shaped, or cylindrical workpieces. Widely used in metal processing, machinery manufacturing, construction engineering, and other fields, it is a key equipment for realizing metal bending and forming processes, and its forming accuracy directly affects the quality of workpieces and subsequent assembly effects.
