Processing method of sintered neodymium-iron-boron spherical magnetic steel

The invention discloses a sintered neodymium iron boron spherical magnetic steel processing method, which comprises a body, and the body comprises magnetic crown assemblies arranged at the two ends of the spherical magnetic steel, a magnetic seat assembly arranged in the middle of the spherical magnetic steel, and a magnetic core arranged at the central axis of the spherical magnetic steel. The magnetic crown assembly comprises an upper magnetic crown arranged at the upper part of the spherical magnetic steel and a lower magnetic crown arranged at the lower part of the spherical magnetic steel; the magnetic seat assembly comprises an upper magnetic seat at the upper end of the middle of the spherical magnetic steel, a lower magnetic seat at the lower end of the middle of the spherical magnetic steel and a mounting hole vertically formed in the center axis of the magnetic seat assembly, and the magnetic core is arranged in the mounting hole. The spherical magnetic steel is divided into the upper magnetic crown
