Small Segment 35SH motor magnet

Our factory is specialized in presicion magnets, our advantage is tight tolerance, dificult shape, high grade.
This product is segment motor magnet, most of motor magnets are segment shape, they can form a circle.
And have requirement of tempeture, so this one working temperature is 150℃, so we choose 35SH material.

Manufacturing Process of Rare Earth Neodymium Magnets

Neodymium, Iron, Boron and a few transition metals will be made into the NdFeB (Neodymium) powder, then fine NdFeB powder will be compacted in a die and sintered, fusing the powder into a solid material. There are 2 forms of pressing: die pressing and isostatic pressing. Sintered parts normally need some finish machining in order to meet final tolerances.

Machining & Tolerance of Rare Eart Neodymium Magnets

NdFeB magnets must be machined using diamond-grinding techniques. Sometimes, machining operations may be performed on Neodymium (NdFeB) materials using carbide tools, but surface finishes thus obtained may be less than optimal. The Standard tolerances for NdFeB (Neodymium) magnets are +/- 0.1mm for ground dimensions, but we can do the most tight tolerance is +/-0.02mm.
