Development of a New Finishing Process Combining a Fixed Abrasive Polishing with Magnetic Abrasive Finishing Process

High quality, highly efficient finishing processes are required for difficult-to-machine materials. Magnetic abrasive (MAF) process is a method that can obtain high accuracy surface using fine magnetic particles and particles, but has poor efficiency. On the contrary, fixed polishing (FAP) material removal efficiency often cannot provide high-quality at nano-scale. Therefore, this work proposes new process, which combines (MAF-FAP). To verify proposed methodology, device was developed experiments on alumina ceramic plates were performed. Furthermore, mechanism of MAF-FAP investigated. In addition, influence parameters characteristics discussed. According to experimental results, achieve high-efficiency brittle hard materials (alumina ceramics) nano-scale surfaces. The roughness plate improved from 202.11 nm Ra 3.67 within 30 min.
