Systematic research about technology parameters influences on the magnetic properties and microstructure of theses magnets have been done. The better parameters of production have been achieved. They are showed as follows: as-cast alloys with the nominal composition Nd15Fe78-xNbxB7 are prepared by induction-melting under argon atmosphere. As-cast alloys are broken under argon atmosphere and filtered through 40# screen. The coarse grain is ball-milled under 120# avgas for 80 min. The ratio of milling ball and grain is 15:1.
