The principle of cylinder tube rolling processing

- Aug 17, 2020-

It is a kind of pressure finishing, which uses the cold and plastic characteristics of the metal at room temperature. The rolling tool applies a certain pressure to the surface of the workpiece, causing the metal on the surface of the workpiece to flow plastically, filling the original residual depression, and reaching the workpiece. The surface roughness value is reduced. Due to the plastic deformation of the rolled surface metal, the surface structure is cold hardened and the grains are thinned, forming a dense fiber and forming a residual stress layer, which increases the hardness and strength, thereby improving the wear resistance and corrosion resistance of the workpiece surface Sex and coordination. Rolling is a non-cutting plastic processing method.
