Abstract:Shear Rheological Polishing (SRP) experiments were carried out on the internal and external surfaces of Quartz Hemispheric Resonator (QHR) to improve the polishing efficiency and surface quality. Based on the shear thickening effect, the rheological fluid can flexibly control the free abrasive particles and move relative to the workpiece surface to achieve material removal. By controlling the flow field of polishing fluid and the interfacial shear stress field, the internal and external surfaces of the QHR can be polished flexibly and efficiently. Experimental results show that the surface roughness of external surface of the QHR decrease from 135.5 nm to 6.6 nm by using an immersion polishing method for 30 min, and the surface roughness of the internal surface decrease from 128.2 nm to 9 nm by using a plunge polishing method for 15 h. The experimental results demonstrate the potential of SRP in the field of QRH polishing.
