No matter what processing method is used for processing, there will always be fine uneven tool marks on the surface of the part, and the phenomenon of staggered and undulating peaks and valleys. Rolling processing principle: It is a pressure finishing process, which uses metal at room temperature. The cold plasticity characteristics of the state use a rolling tool to apply a certain pressure on the surface of the workpiece to make the surface metal of the workpiece produce plastic flow, and fill it into the original residual low concave wave trough, so as to reduce the surface roughness of the workpiece. 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 Sexuality and coordination. Rolling is a non-cutting plastic processing method.
