Piston rod machining technology and use

The piston rod is a connecting part that supports the piston to do work. Most of the piston rods are used in the cylinder and cylinder movement executing parts. It is a moving part with frequent movement and high technical requirements. Taking hydraulic cylinder as an example, it consists of: cylinder, piston rod (cylinder rod), piston and end cap. The quality of its processing directly affects the life and reliability of the entire product. The piston rod requires high processing, and its surface roughness is required to be Ra0.4-0.8um, and the coaxiality and wear resistance are strictly required. The basic feature of cylinder rods is the processing of elongated shafts, which are difficult to process and have always plagued the processing personnel.

The piston rod adopts rolling processing, because the residual pressure stress on the surface layer is left on the surface layer, which contributes to the sealing of surface micro cracks and hinders the expansion of the erosion effect.

These bushes, bushing are used to diminish vibration, impact or shock as well as to reduce noise level during application use.
