First of all, we must understand the manufacturing process of quenched and tempered piston rod. It is formed by rolling. A cold hardening layer is formed on the surface of the rolling surface, which helps to reduce the elastic and plastic deformation of the contact surface of the grinding pair, improve the wear resistance of the surface of the cylinder rod, and avoid the burns caused by grinding.

The electroplating treatment of piston rod is not simple, but also requires a higher technical content, it is necessary to remind everyone about this.
