摘要： A magnet holding jig comprises a platform and first and second holders disposed on opposite sides of the platform. The platform is provided with channels, the holders are comb-shaped to define digits and slits, the channels and the slits being aligned to define guide paths for permitting entry of a cutting tool therein, and the holders are also configured as digitate hooks. The holder hooks are in contact with a rare earth magnet block resting on the platform. The holders are pushed inward at their lower portions so as to bring each hook digit of the second holder in pressure abutment with the magnet block at a higher level than each hook digit of the first holder for thereby holding the magnet block in place on the platform.

摘要： In a method for multiple cutoff machining a rare earth magnet block, a cutting fluid feed nozzle having a plurality of slits is combined with a plurality of cutoff abrasive blades coaxially mounted on a rotating shaft, each said blade comprising a base disk and a peripheral cutting part. The slits in the feed nozzle into which the outer peripheral portions of cutoff abrasive blades are inserted serve to restrict any axial run-out of the cutoff abrasive blades during rotation. Cutting fluid is fed from the feed nozzle through slits to the rotating cutoff abrasive blades and eventually to points of cutoff machining on the magnet block.
