| description | The Si3N4 ceramic cylindrical rollers serve as the rolling elements of precision bearings, exhibiting excellent material properties such as high hardness, good resistances of wear, high temperature and corrosion. These rollers are particularly advantageous for mechanical equipment that operates operating under heavy loads and at high speeds. The quality of the outer surface of these rollers, which forms the primary working interface of a rolling bearing, significantly affects both the precision of motion and the lifespan of the bearing. Given the high hardness and brittleness of Si3N4 ceramic, processing this material presents considerable challenges. This study introduces a novel double-side grinding method using Diamond Film Pads (DFPs) to process Si3N4 cylindrical rollers. We analyze the effects of key process parameters—loading pressure, speeds ratio, and abrasive size—on the Material Removal Rate (MRR) and surface quality through single-factor experiments. The findings indicate that the maximum achieved MRR is 1.237 μm/min. Abrasive size has the most significant influence on MRR, followed by loading pressure and speed ratio. A decrease in abrasive size correlates with a lower mean surface roughness Ra, whereas using larger abrasives with higher loading pressure and a speed ratio of 1 can decrease Ra values. For smaller abrasives, reducing loading pressure and extending processing time can improve the surface roughness Ra. Remarkably, this research achieved defect-free surfaces of ceramic cylindrical rollers with a minimum average roughness of 6 nm and a deviation of 2 nm. The study demonstrates that high-quality surface processing of Si3N4 cylindrical rollers by double-side grinding with DFPs is achievable. Moreover, this process only requires the application of addition of deionized water, making it environmentally friendly. |
