Previous researches have confirmed that MCF (magnetic compound fluid) slurry shows outstanding performance in the Nano-precision polishing of flat surfaces and V-grooves. However, no investigations have been conducted on the polishing of aspheric surfaces using MCF slurry. In this work, a novel method employing a doughnut-shaped MCF polishing tool and a 6-DOF manipulator has been proposed for the aspheric surface polishing. At first, the distribution of abrasive particles is detected by SEM and EDX mapping. Then, the time consumption for forming stable polishing tool and its final appearance are investigated. A plate-shaped aluminum alloy workpiece that can be considered as a kind of aspheric elements with infinite curve radius is adopted in the experiment. As a typical experimental result, the polished area and the profiles of cross section after every 30min polishing are recorded in which a concentric circle polishing area is attained with almost Ø34 mm outer diameter and Ø15 mm inner diameter, the material removal is marked by maximum removed depth and the surface roughness Ra decreases from 125nm to almost 11nm after 90 min polishing, confirming that the proposed method has the potential to polish aspheric surfaces.
