Rolling Machine (Form rolling machine）

Form rolling is one of the plasticity processes that deforms a material by applying a strong force. The plasticity of the material (the property of the material not to return to its original shape after deformation) is used to form the material.
The plasticity of the material is used to press the rolling die (a tool with a threaded cross-section) against the rotating workpiece.
The material is formed (plastically deformed) by pressing the rolling die (a tool with a thread-shaped cross section) against the rotating workpiece and raising it.
