永久磁石を利用したユニット方式磁気研磨装置の開発に関する研究

抄録

In this paper, a unit system magnetic abrasive finishing apparatus is newly developed in which five ferrite permanent magnets are used as generating elements of magnetic flux, instead of the conventional finishing apparatus using an electromagnetic coil which is large in size and heavy in weight. This unit system finishing apparatus is very easily installed on the table or the carriage of ordinary machine tools, and is small in size and light in weight. From the experiments, it is confirmed that the finishing performance of this new apparatus matches for that of the conventional apparatus using an electromagnetic coil.
