1. hydraulic piston rod machining process

The connecting rod is made of 35 steel processing: precision cold drawing forming a turning a continuous medium frequency induction hardening a pre grinding outer circle of a pre grinding cylindrical external grinding super finishing chrome plating to super fine grinding tempering hydrogen. In order to improve the surface quality and corrosion resistance of piston rod, superfine finishing process was added before chromium plating.

Before plating test - installed rack - chemical degreasing, electrolysis degreasing - washing - Pickling - water - activated anti moment -- piston rod chrome - recycling washing -- washing - unloading rack - Test
