Basic principle of cylinder tube

Processing principle: It is a pressure finishing process, which uses the cold plastic characteristics of the metal at room temperature, and uses a rolling tool to apply a certain pressure to the surface of the workpiece to cause plastic activity on the surface metal of the workpiece, filling it to the initial residual low In the concave valley, the roughness of the surface of the workpiece decreases. Because the plastic deformation of the rolled surface metal makes the surface layer cold-hardened and the grains are thinned to form a fine fiber and form a residual stress layer, the hardness and strength are improved, and then the wear resistance and corrosion resistance of the workpiece surface are improved Sex and cooperation. Rolling is a non-cutting plastic processing method.
