By this way, the effects of current density and superfinish on the corrosion resistance of piston rods in Santana shock absorbers were investigated and established.

This paper analyzed the superfinishing principle of engineering ceramic material, studied the effect of superfinishing process parameters, such as the pressure, amplitude and frequency of grinding head, the rotate speed of workpiece, and the machining time, on the workpiece surface roughness, and obtained a group of optimized superfinishing process parameters.

Dissertating the five very important aspects that must be considered when we select whetstone before doing superfinishing of bearing parts.
