Rolling Process
▲What is rolling ?
★Rolling is a pressure finishing process that utilizes the cold plasticity characteristics of metal at room temperature and strengthens the surface of the rolling tool and the workpiece to obtain a smooth, mirror-like metal surface.
The main goal of roller polishing is to give the workpiece an ultra-high quality smooth surface or to meet high surface accuracy requirements; while the roller polishing tool uses one or more rollers or balls to exert pressure to plasticize and deform the surface of the workpiece.
▲The principle of roller polishing knife
★"At the contact point between the roller burnisher and the workpiece, the force of the roller burnisher will process the surface area of the material by extrusion and roller burnishing; if the stress is higher than the yield strength of the material, the material close to the surface of the workpiece will begin to flow and produce plasticity deformation.
The convex peaks on the originally uneven surface will be pressed vertically into the surface, and then filled into the original remaining low concave troughs; thereby reducing the surface roughness of the workpiece and achieving the effect of rolling and extruding.
This processing method can not only improve the surface finish in a short time, but also improve the hardness and mechanical properties of the workpiece. It also greatly improves the wear resistance and corrosion resistance; and due to the generation of compressive residual stress, it can achieve durability surface effect.
