Magnet de neodim
Neodymium magnet (aka NdFeB magnet), is the third generation of rare earth magnet, which is composed of Neodymium, Iron, Boron and a few transition metals. With high remanence, high coercive force, high energy product, and high performance /cost, Neodymium magnet is currently the strongest magnet available in the world.
Manufacturing Process
Neodymium, Iron, Boron and a few transition metals will be mixed into the Neodymium powder, then fine Neodymium powder will be compacted in a die and sintered, fusing the powder in a solid state. There are two ways of pressing die pressing and isostatic pressing. Sintered parts normally need some finish machining in order to meet final tolerances.
Machining & Tolerance
Generally, Neodymium magnet must be machined using diamondgrinding techniques. Sometimes, machining operations may be performed on Neodymium materials with carbide tools, but surface finishes thus obtained may be less than optimal.
