The invention discloses an efficient ultra-precise shear thickening and chemical synergy polishing method. The polishing method comprises the following steps that 1, workpieces are fixed on a polishing and fixing disc of implementation equipment; 2, an efficient ultra-precise shear thickening and chemical synergy polishing solution is prepared, specifically, the polishing solution comprises polishing abrasive particles or micro-powder, a shear thickening enhanced phase, water and green chemistry environment-friendly substances; 3, the prepared polishing solution is added into a dust cover, anda polishing solution circulating device is started, so that the polishing solution is supplied to the surfaces of the workpieces through polishing tools; and 4, driving devices and driving mechanismsare started, so that the polishing tools move relative to the workpieces, and the machining surfaces of the workpieces are polished. According to the polishing method, active constraint of the solution flow boundary and active control of the flow of the polishing solution and the synergy between shear thickening and the green chemistry are utilized, so that the machining efficiency and the machining precision are improved, and the types of machinable materials and the surface shape are increased.
