Skiving & Roller Burnishing cylinder tubes and honed tubes are the most common tube that used in hydraulic cylinders.The honed cylinder tubes which are processed by Skiving & Roller Burnishing have a surface residual compressive stress left on the surface layer, which contributes to the sealing of the surface micro crack and hinders the expansion of the erosion effect. Thereby, the surface corrosion resistance is improved, and the generation or expansion of the fatigue crack can be delayed, thereby improving the fatigue strength of the honed tube.
Through Roller burnish forming, the rolling surface forms a cold hardening layer, which reduces the elastic and plastic deformation of the grinding contact surface, thereby improving the wear resistance of the inner wall of the honing pipe and avoiding burns caused by grinding.
After rolling, the inside surface roughness value of honed tube is reduced, which can improve the tolerance fit property.
After knowing the advantages of the honing process compared to Skiving & Roller burnishing process, people can easily determine which production process to use when they need to purchase the honed cylinder tubes. Datong Hydraulic is one of the leading hone tube manufacturers & suppliers in China, it can produce honing tubes with both of the above manufacturing processes.
