Rolling processing principle of cylinder tube

- Jun 22, 2020-

It is a pressure finishing process, which uses the cold and plastic characteristics of the metal at room temperature, and uses a rolling tool to apply a certain pressure to the surface of the workpiece, causing the metal on the surface of the workpiece to plastically flow and fill the original remaining low concave valley , And the roughness value of the workpiece surface is reduced. Due to the plastic deformation of the rolled surface metal, the surface structure is cold hardened and the grains are thinned to form a dense fiber and form a residual stress layer. Sex and cooperation. Rolling is a non-cutting plastic processing method.
