The precision piston rod undergoes rolling processing to enhance its surface corrosion resistance, delay the occurrence or propagation of fatigue cracks, and thus improve the fatigue strength of the cylinder rod. Through rolling, a layer of cold-worked hardened layer is formed on the rolling surface, which reduces the elastic and plastic deformation of the grinding contact surface, thereby enhancing the wear resistance of the cylinder rod surface and preventing burns caused by grinding. After rolling, the reduction in surface roughness can improve the matching performance. At the same time, when the piston rod moves, the friction damage to the sealing ring or seal is reduced, thereby extending the overall service life of the oil cylinder. Rolling technology is an efficient and high-quality technical means. The processing technology of the piston rod is also an important component of the piston rod. The processing technology directly affects the quality and service life of the piston rod. Rolling processing is generally used for the processing of piston rods because this method can enhance the surface corrosion resistance of the piston rod, delay the occurrence and propagation of fatigue cracks, and thus improve the fatigue strength of the piston rod.
