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

摘要

PURPOSE: A multiple-cutting method of rare earth magnets, a grinding supply feed nozzle, a magnet fixing jig, and a multiple-cutting apparatus of rare earth magnets with the same are provided to improve cutting accuracy by effectively supplying a small amount of cutting fluid to a cut point. CONSTITUTION: A multiple-cutting method of rare earth magnets comprises followings. Multiple cutting grindstone blades are arranged in a rotary shaft(12) along an axial direction. The grindstone has a grindstone outer blade on an outer edge of a bedplate. When the outer peripheral part of the grindstone is inserted into slit of a grinding fluid supply nozzle, the grinding fluid is ejected from the slit of the grinding fluid supply nozzle(2), and the cutting grindstone blade is rotated to multiple-cut rare earth magnets. The grinding fluid supply nozzle has a grinding fluid inlet port and a plurality of slits.
