Process flow: ingredients → smelting ingot/belt spinning → powder making → profiling → sintering and tempering → magnetic detection → grinding process → pin cutting process → electroplating → finished product. Among them, the ingredients are the basis, and the sintering and tempering is the key. NdFeB magnet blank production tools and performance testing tools: smelting furnace, belt spinning furnace, jaw breaking machine, jet mill, compression molding machine, vacuum packaging machine, isostatic press, sintering furnace, heat treatment vacuum furnace, magnetic performance test Meter, Gauss meter. NdFeB magnet machining tools: centerless grinding, spheronization machine, double-end grinding, flat grinding, slicer, double-sided grinding, wire cutting, special-shaped grinding, etc.
