Cutting tool processing principle The rolling head can make use of the plastic deformation of metal at room temperature to flatten the microscopic unevenness of the surface of the workpiece so as to achieve the purpose of changing the surface structure, mechanical characteristics, shape and size. Therefore, this method can achieve both smoothing and strengthening purposes at the same time, which cannot be achieved by grinding and turning.
No matter what kind of metal processing tool is used for processing, there will always be fine uneven tool marks on the surface of the part, and the phenomenon of staggered undulating peaks and valleys.
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 Sexuality and coordination. Rolling is a non-cutting plastic processing method
