Production process of servo motor magnetic tile
Jul 04, 2018

Servo motor magnets are made of different materials and types, so their production industries are also different. The servo motor magnetic tile is mainly composed of sintered ferrite, and the NdFeB magnetic tile can be divided into two types of sintering and bonding.


At present, in the process of production and processing, the production process of servo motor magnetic tile mainly includes wet pressure anisotropy, dry pressure homogeneity, dry pressure and the like. The difference between the opposite sex and the sameness is whether there is an orientation magnetic field when the press is formed.


Next, we briefly introduce the processing flow of the wet-pressure anisotropy of the servo motor magnetic tile: raw material - pre-burning - coarse crushing (one ball milling) - batching - secondary ball milling (wet grinding) - magnetic field forming - - Sintering - Grinding - Cleaning - Magnetizing. Since the molding slurry contains moisture, the magnetic particles are easily deflected in the magnetic field, so that a higher degree of orientation is obtained than the dry pressing property, and the performance is higher.


Usually in the sintering process of servo motor magnetic tile, the main process can be summarized as: batching, smelting, crushing, milling, magnetic field forming, isostatic pressing, vacuum sintering and tempering, wire cutting and other processing, electroplating, and finally magnetization. .
