精加工难加工材料需要高质量、高效的精加工工艺。磁力研磨精加工（MAF）工艺是一种利用细小的磁性颗粒和磨粒获得高精度表面的精加工方法，但精加工效率较差。相反，固定磨料抛光（FAP）是一种可以获得高材料去除效率但往往无法提供纳米级高质量表面的抛光工艺。因此，本工作提出了一种新的精加工工艺，将磁力磨料精加工工艺与固定磨料抛光工艺（MAF-FAP）相结合。为了验证所提出的方法，开发了一种精加工装置，并对氧化铝陶瓷板进行了精加工实验。此外，还研究了MAF-FAP过程的机理。此外，还讨论了工艺参数对精加工特性的影响。根据实验结果，该工艺可以实现脆硬材料（氧化铝陶瓷）的高效精加工，并可以获得纳米级的表面。 30 min内氧化铝陶瓷板的表面粗糙度从202.11 nm Ra改善至3.67 nm Ra。
High quality, highly efficient finishing processes are required for finishing difficult-to-machine materials. Magnetic abrasive finishing (MAF) process is a finishing method that can obtain a high accuracy surface using fine magnetic particles and abrasive particles, but has poor finishing efficiency. On the contrary, fixed abrasive polishing (FAP) is a polishing process can obtain high material removal efficiency but often cannot provide a high-quality surface at the nano-scale. Therefore, this work proposes a new finishing process, which combines the magnetic abrasive finishing process and the fixed abrasive polishing process (MAF-FAP). To verify the proposed methodology, a finishing device was developed and finishing experiments on alumina ceramic plates were performed. Furthermore, the mechanism of the MAF-FAP process was investigated. In addition, the influence of process parameters on finishing characteristics is discussed. According to the experimental results, this process can achieve high-efficiency finishing of brittle hard materials (alumina ceramics) and can obtain nano-scale surfaces. The surface roughness of the alumina ceramic plate is improved from 202.11 nm Ra to 3.67 nm Ra within 30 min.
