Abstract:

This work is focused on experimental investigation of hydrodynamic polishing (HDP) as a Nano polishing method. The soft rubber tool and the work piece are submerged in slurry during hydrodynamic polishing. An elastohydrodynamic film is formed between the tool and the work piece due to the tool rotation which is responsible for Nano polishing. A HDP experimental setup was fabricated and experiments were conducted on non-shrinking steel 60 HRC with colloidal alumina suspensions of different particle sizes. The experiments study shows the effect of main factors such as spindle speed and constant load at different polishing times. The best surface finish of 0.504 µm was obtained using 75 µm abrasive particle size colloidal suspension at 0.4 N load, 4000 rpm spindle speed and 3 min of polishing time. The change in surface morphology and topography due to polishing also confirm the efficacy of the HDP process.
