摘      要：Magnetic fluid-assisted finishing has been verified both theoretically and experimentally as an effective fabrication technology for opti- cal mirrors and *** purpose of this paper is to introduce a novel design of polishing tool and demonstrate the possible applica- tions of this *** work includes studying the viscosity of the magnetic suspensions of micrometer-sized Carbonyl iron particles under the influence of a magnetic *** the cases of magnetizable suspension with and without abrasive cerium oxide par- ticles are studied for their ensuing polishing *** of material removal function is conducted using a Wyko Nat1100 *** to reduce surface roughness with the proposed tool are also performed using a K9 mirror as the *** show that the surface accuracy is improved over three times to less than 0.5 nm after two cycles of polishing.
