<P>PROBLEM TO BE SOLVED: To provide a technology of sufficiently recovering a machining deterioration layer on the surface of a magnet by a practical and simple method. <P>SOLUTION: A magnet element assembly is immersed in an alloy melt principally containing a rare-earth element. The magnet element assembly is a rare-earth sintered magnet such as an NdFeB group rare-earth sintered magnet. The magnet element assembly is advantageously machined to have a prescribed thickness, e.g., 2 mm thick or below by machining. The melting point of the allow melt is preferably 1,000°C or below. Further, the alloy melt contains the rare-earth element at a rate of 50atom% content or over. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
