Introduction to piston rod processing technology!

The use of rolling processing can improve the surface corrosion resistance and delay the generation or expansion of fatigue cracks, thereby improving the fatigue strength of the oil cylinder rod. By rolling forming, a cold work hardening layer is formed on the rolling surface, reducing the elastic and plastic deformation of the contact surface of the grinding pair, thereby improving the wear resistance of the cylinder rod surface and avoiding burns caused by grinding. After rolling, the reduction of surface roughness value can improve the fitting properties. At the same time, it reduces the friction damage to the sealing ring or sealing element during the movement of the oil cylinder rod piston, and improves the overall service life of the oil cylinder. Rolling process is an efficient and high-quality process measure.
