Magnetorheological finishing (MRF), considered as a promising polishing technique that can finish a nano-level smooth surface and free of surface or subsurface damage, has been widely utilized in ultra-smooth polishing of hard-to-machine materials. MRF process is mainly rely on shear stress to remove material. In this study, α-cellulose used as an additive agent to improve the rheological properties of magnetorheological polishing slurry (MRPS). The rheometer measurement results and polishing results showed that: (1) α-cellulose can enhance the shear stress of MRPS, but increased the apparent viscosity of MRPS. (2) α-cellulose can effectively improve the stability of MRPS, when the weight fraction of α-cellulose was 0.6 wt%, both stability and internal uniform of MRPS can be obtained. (3) If the weight fraction of α-cellulose was bigger than 0.6 wt%, the machining ability of MPRS was stable and the smooth polished surface can be obtained.

磁流变精加工（MRF）被认为是一种有前途的抛光技术，可以完成纳米级的光滑表面并且没有表面或亚表面损伤，已广泛用于难以加工的材料的超光滑抛光中。MRF过程主要依靠剪切应力来去除材料。在这项研究中，α-纤维素用作添加剂，以改善磁流变抛光浆（MRPS）的流变性。流变仪的测量结果和抛光结果表明：（1）α-纤维素可以增强MRPS的剪切应力，但增加了MRPS的表观粘度。（2）α-纤维素可以有效地改善MRPS的稳定性，当α-纤维素的重量分数为0.6wt％时，可以获得MRPS的稳定性和内部均匀性。（3）如果α-纤维素的重量分数大于0。
