Document Type and Number:
Japanese Patent JP2023141524
Kind Code:
A
Abstract:
To efficiently manufacture a wide variety of R-T-B sintered magnets in response to user requests.SOLUTION: A manufacturing method of an R-T-B sintered magnet according to the present disclosure includes a step of preparing an R-T-B sintered magnet material block, a wire electrical discharge machining step of manufacturing a plurality of R-T-B sintered magnet material pieces from the R-T-B sintered magnet material block by cutting the R-T-B sintered magnet material block at an average machining speed of 2.0 mm/min or more by wire electrical discharge, and a surface processing step of grinding or polishing the electrical discharge machined surface of each of the plurality of R-T-B sintered magnet material pieces.SELECTED DRAWING: Figure 3
