磁気研磨法とその応用

抄録

Some combinations of different phenomena may cause unexpected yet rather beneficial effects. For instance, the combination of a magnetic field with the action of abrasive against a work material gives rise to a new magnetic field assisted finishing process, which shows the potential to overcome problems with more conventional surface finishing processes. Because magnetic flux flows without being impeded through nonferrous work material, it is possible to influence the abrasive acting force and the abrasive motion against a work surface by controlling the magnetic field. This causes the finishing operation not only on the easily accessible surfaces but also on the areas that are hard to reach by conventional mechanical techniques. This is a distinct advantage of magnetic field assisted finishing. This report presents the finishing principle, characteristics, and mechanism of the magnetic field assisted finishing process. In addition, a few examples of industrial applications are presented.
