| 简介 |
SOLUTION : A fixing jig for a rare earth sintered magnet includes a first clamper 31 for forming a base where a rare earth sintered magnet M is placed, a second clamper 32 arranged on the magnet M, and a pressing member 33 for providing pressing force to the magnet M from one side or both sides of a top and a bottom of the magnet M to the clampers 31, 32. The fixing jig of the rare earth sintered magnet is configured such that a groove 311 is formed approximately horizontally from one side or both sides of a surface to be cut toward insides of the clampers 31, 32 in the vicinity of a contact part with the magnet M of one side or both the sides of the clampers 31, 32, and thereby, an elastic piece 312 is formed in the magnet side of the clampers 31, 32, and also the magnet M is supported between the clampers 31, 32 using the resilient force generated by movement to an upper part or a lower part of the elastic piece 312.
EFFECT : A rare earth sintered magnet block with a height can be cut with high accuracy by suppressing formation of a level difference in a cut surface by using a cutting-off wheel blade which has a small effective diameter and is thin in multi-cutting of a magnet M.
