Abstract

Using the standard MR fluid with 0.5 Pa·s initial viscosity, the main parameters such as working gap, relative velocity between the polishing wheel and the workpiece, concentration of CeO₂ and polishing time are analyzed experimentally on the home developed MRF system, whose polishing wheel combines self-rotation movement with co-rotation. The polishing practicability of the technology is verified for polishing a mirror made from K9, the roughness of the experimenting piece has decreased to 0.6315 nm Ra from initial 10.98 nm Ra after MRF for 28 min.
