It is a moving component that moves frequently and has high technical requirements. Taking the hydraulic cylinder as an example, it is composed of a cylinder barrel, a piston rod (oil cylinder rod), a piston, and an end cover. The quality of its processing directly affects the life and reliability of the entire product. The piston rod is usually processed by rolling. Through rolling forming, a cold work hardening layer is formed on the rolling surface, which reduces the elasticity 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. The piston rod also needs to be drilled after rolling forming.
