    The swing oil cylinder is the main component of construction machinery, and the quality of its processing directly affects the life and reliability of the entire product. The traditional machining method is: broaching cylinder body-fine boring cylinder body-grinding cylinder body. Now let's talk about the small knowledge of rolling processing of swing cylinders!
    Rolling processing is used, because the surface layer is left with residual compressive stress on the surface, which helps to close the surface of small cracks and hinder the expansion of erosion. Thereby, the anti-corrosion ability of the surface is improved, and the generation or expansion of fatigue cracks can be delayed, thereby increasing the cylinder fatigue strength.
    Through roll forming, a cold hardened layer is formed on the rolled surface, which reduces the elastic and plastic deformation of the contact surface of the grinding pair, thereby improving the abrasion resistance of the inner wall of the cylinder barrel and avoiding burns caused by grinding.
    After rolling, the surface roughness value is reduced, which can improve the mating properties.
    The above is about the rolling process of the swing cylinder, and I hope it will be helpful to everyone. If you still have questions about the swing cylinder, please call! Or follow our company website for more details! If you need a swing cylinder, please contact our company!
