Rolling cutters and rolling heads can use metal plastic deformation at room temperature to smooth out the microscopic unevenness of the workpiece surface and then achieve the intention of changing the surface structure, mechanical characteristics, shape and scale, no matter what kind of metal processing tool is used for processing, There will always be fine uneven knife marks on the surface of the parts, showing the phenomenon of intertwined rugged peaks and valleys. The rolling knife is a mechanical non-cutting plastic processing method that uses the principle of mechanical extrusion to obtain a mirror-like metal appearance. Squeeze knife
Rolling cutter, rolling head It is a kind of pressure finishing. It uses the cold plastic characteristics of metal at room temperature. Rolling cutters are used to apply a certain pressure on the surface of the workpiece to make the surface metal of the workpiece produce plastic flow. The original residual low concave wave trough, and the roughness value of the surface of the workpiece decreases. Due to the plastic deformation of the surface layer metal being rolled, the surface layer structure is cold hardened and the crystal grains become finer, forming a fine fiber shape and forming a residual stress layer, the hardness and strength are improved, and then the wear resistance and corrosion resistance of the surface of the workpiece are improved. Sexuality and coordination. Rolling is a non-cutting plastic processing method, so this method can achieve both smoothing and strengthening purposes at the same time, which is impossible for grinding and turning.
Rolling processing is a kind of chipless processing. A certain pressure is applied to the surface of the workpiece through a certain form of rolling stuff. The plastic deformation of the metal is used at room temperature to smooth out the microscopic unevenness of the surface of the workpiece and then achieve the purpose of changing the surface structure, mechanical properties, shape and scale. Therefore, this method can be used to achieve both smoothing and strengthening purposes at the same time. Inner hole calender knife
Rolling processing has a wide range of applications and can be used in large, medium and small factories. No matter in terms of processing quality, production efficiency, production cost, etc., rolling processing is a relatively superior processing method. In some respects, it can completely replace finishing processes such as fine grinding, grinding, and honing. At present, the processing methods of transferring external force to rolling objects can be divided into three types: mechanical, rolling and spring. According to the processing properties, rolling cutters can be divided into two types: light finishing and strengthening processing.
