Honing tube

     Honing cylinder barrel is a high-precision steel pipe material, which integrates the advantages of no oxide layer on the outer wall, high pressure without leakage, high precision, high finish, no deformation after cold bending, flaring, flattening without cracks, etc. It is mainly suitable for mechanical processing.

     Honing cylinder barrel adopts rolling processing. Since the surface layer has residual compressive stress on the surface, it helps to close the surface micro cracks and hinder the expansion of erosion. Thereby improving the surface corrosion resistance and delaying the generation or expansion of fatigue cracks, thereby improving the fatigue strength of the honing cylinder barrel. Through rolling forming, a cold work hardening layer is formed on the rolling surface, which reduces the elastic and plastic deformation of the contact surface of the grinding pair, thereby improving the wear resistance of the inner wall of the honing cylinder barrel and avoiding burns caused by grinding. After rolling, the reduction of surface roughness value can improve the matching properties.

    Rolling processing is a chipless processing. It uses the plastic deformation of metal at room temperature to flatten the microscopic unevenness of the workpiece surface to achieve the purpose of changing the surface structure, mechanical properties, shape and size. Therefore, this method can achieve the two purposes of finishing and strengthening at the same time, which cannot be achieved by grinding.
