The invention belongs to the technical field of metal mechanical cutting process methods, and relates to a method for suppressing external grinding vibration of a thin-wall rotary body part. According to the principle, special oil liquid is injected into an inner cavity of the thin-wall rotary body part, so that the dynamic rigidity and inherent frequency of a workpiece are adjusted, internal damping is enhanced, and therefore the effect of restraining grinding vibration is achieved. And meanwhile, adaptive matching of different machining parameters, workpiece materials and workpiece shapes can be achieved by adjusting and optimizing parameter variables such as the oil type and the injection volume, the oil has the effect of reducing grinding heat, and finally the purposes of restraining harmful grinding vibration and improving the workpiece surface machining quality are achieved. 本发明属于金属机械切削加工工艺方法技术领域，涉及一种薄壁回转体零件外圆磨削振动抑制的方法。薄壁回转体零件外圆磨削振动抑制的工艺方法及配套工装，其原理是通过在薄壁回转体零件内腔注入特种油液，并以此调节工件自身动态刚度、固有频率，增强内阻尼，从而达到抑制磨削振动的
