Rolling processing principle of Honed Tube For Hydraulic Cylinder

- Dec 09, 2020-

Rolling processing principle: It is a pressure finishing process, which uses the cold plastic characteristics of metal at room temperature, and uses rolling tools to apply a certain pressure on the surface of the workpiece, so that the surface metal of the workpiece produces plastic flow and fills it into the original residue In the low concave wave trough, the surface roughness value of the workpiece is reduced. Due to the plastic deformation of the rolled surface metal, the surface structure is cold hardened and the crystal grains become finer, forming a dense fiber shape, and forming a residual stress layer, which improves 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.
