The dificiency in the variety of available magnetic abrasives results in a narrow range of finishing performance of the Magnetic abrasive finishing process. To break through this situation, this study develops a Ni〜based flaky magnetic polishing tools, which consists of thin layers manufactured using an electroforming technique, and which is made without conventional abrasive. Because of the flaky structure, the edges broken during the finishing process effectively renew the cutting edges. It has an easy axis of magnetization and is magnetized such the flat surface is normal to the workpiece surface. This localizes the contact points of the magnetic polishing tools against the peaks of the uneven surface of the workpiece. While existing magnetic abrasive removes material following the overall form of the surface, the Ni-based magnetic polishing tools remove the material from the peaks of the surface. Accordingly, the Ni-based magnetic polishing tools achieve precision finishing of SUS 304 stainless steel tubes despite having lower material removal than the existing magnetic abrasive.
