  • Method for multiple cutoff machining of rare earth magnet
    Patent number: 10391602
    Abstract: A rare earth magnet block is cutoff machined into pieces by rotating a plurality of cutoff abrasive blades. Improvements are made by starting the machining operation from the upper surface of the magnet block downward, interrupting the machining operation, turning the magnet block upside down, placing the magnet block such that the cutoff grooves formed before and after the upside-down turning may be aligned with each other, and restarting the machining operation from the upper surface of the upside-down magnet block downward until the cutoff grooves formed before and after the upside-down turning merge with each other.
