The invention belongs to the technical field of machining of precise inner holes of hydraulic matching parts, and discloses a graded honing method suitable for the precise inner holes of the hydraulic matching parts. A sintered oilstone honing device is used, a numerical control multi-station vertical honing machine tool is used for installing the honing device, different allowances are removed in a grading mode, oilstones with different granularities and certain lengths are selected, different honing parameters are set, and different index requirements are met in a grading mode. And the inner hole surface microscopic quality is improved. 本发明属于液压偶件精密内孔加工技术领域，公开了一种适用于液压偶件精密内孔的分级珩磨方法。使用烧结油石珩磨器，利用数控多工位立珩机床安装珩磨器，分级去除不同余量，选用不同粒度一定长度油石，设置不同珩磨参数，分级达到不同指标要求，通过该方法能够提升液压偶件精密内孔直线度，控制内孔一致性，改善内孔表面微观质量。
