Abstract
The purpose of this study is to propose the internal magnetic polishing method of grooves of magnetic materials, and to examine the polishing characteristics. Most of dies as workpieces are made of magnetic materials. When such dies are finished by the magnetic polishing, some problems are liable to occur; for example, ferromagnetic particle remains on the surface of workpieces by the magnetic attraction force. In addition, in the groove polishing of magnetic materials, the ferromagnetic particle is concentrated to the groove edge, and there is a problem that the polishing becomes insufficient at the inner surface. In this paper, by clarifying of the internal magnetic polishing characteristics in groove, polishing mechanism in various grooves was examined.
