METHOD AND APPARATUS FOR MULTIPLE CUTOFF MACHINING OF RARE EARTH BLOCK, CUTTING FLUID FEED NOZZLE, AND MAGNET BLOCK SECURING JIG

In a method for multiple cutoff machining a rare earth magnet block, a cutting fluid feed nozzle (2) having a plurality of slits (21) is combined with a plurality of cutoff abrasive blades (11) coaxially mounted on a rotating shaft, each said blade (11) comprising a base disk and a peripheral cuttin...

Zusammenfassung:In a method for multiple cutoff machining a rare earth magnet block, a cutting fluid feed nozzle (2) having a plurality of slits (21) is combined with a plurality of cutoff abrasive blades (11) coaxially mounted on a rotating shaft, each said blade (11) comprising a base disk and a peripheral cutting part (11a). The slits (21) in the feed nozzle (2) into which the outer peripheral portion of cutoff abrasive blades (11) are inserted serve to restrict any axial run-out of the cutoff abrasive blades (11) during rotation. Cutting fluid is fed from the feed nozzle through slits (21) to the rotating cutoff abrasive blades (11) and eventually to points of cutoff machining on the magnet block.
