Commonly used rough grinding methods for powerful magnets

During the production of magnets, there is a process of cutting and grinding raw materials, such as cylindrical and square NdFeB blanks. What is the commonly used rough grinding method for powerful magnets?

The method of the cylindrical grinder is the main grinding method of the blank of the cylindrical magnet, mainly for the rough grinding and fine grinding of the outer diameter of the cylindrical magnet blank. It is required according to the customization requirements corresponding to the outer diameter tolerance of the finished magnet.

Fine processing to the most accurate range of custom requirements, after cylindrical grinding, cylindrical magnets enter the next process, viscose processing of magnet beams, and preparation for batch slicing. Grinding cylindrical NdFeB blanks are generally Coreless grinding and double-end flat grinding are used. The blanks of special-shaped NdFeB such as tile-shaped magnets or sectors are multi-station grinders. The usual grinding methods of square-shaped NdFeB are generally flat grinding, two-end surface grinding, Internal grinding, external grinding.

NdFeB anisotropic sintered magnetic tiles are used in many permanent magnet materials, and their cost-effective advantages have become the most widely used and high-volume permanent magnet materials in the world. The traditional production of permanent magnet blanks requires ball milling, precipitation and dehydration in turn. , pressing green body and sintering molding and other steps, feeding, discharging and conveying must be completed by manpower, the cost of producing magnets is high, the labor intensity of workers is high, and the slurry will be exposed to the air during this process, which is easy to be damaged. Pollution, and the use of precipitation dehydration, it takes a long time, which will seriously affect the efficiency of production.

The above are some methods of magnet blank grinding and the cost of blank grinding. The content of this article is for reference only, and everything is based on the actual situation.
