The seventh process of magnet production process: cylindrical grinding

Magnet blanks are put into storage after magnetic properties are tested and judged to be qualified. According to the order demand out of the warehouse into the cylindrical grinder workshop. The commonly used grinding methods for square NdFeB magnet blanks are: flat grinding, two end surfaces grinding, internal grinding, external grinding, etc. Cylindrical NdFeB magnet blank is often used without core grinding, and double end flat grinding. Tile-shaped magnets, fan-shaped, special-shaped NdFeB magnet blanks are multi-station grinding machines.

The cylindrical grinding machine mainly carries out rough grinding and fine grinding for the outer diameter size of the cylindrical blank. The rough grinding grinds off the oxidized black skin generated during sintering. The fine grinding is within the tolerance range according to the outer diameter tolerance requirements of the finished magnet on the order. After the cylindrical grinding processing, all the pillars will enter the next process, and the viscose processing of the magnet optical column will prepare for batch slicing processing.To judge whether the magnet product is qualified, not only the performance of the standard, the magnet size tolerance is worth controlling, but also directly affects its product performance and application. The accurate guarantee of magnet dimensional tolerance values also directly depends on the factory's product manufacturing strength. Processing equipment with the economic and social market needs to be constantly updated, more efficient equipment and industrial processing automation trends, not only to meet the growing needs of customers for magnet precision, but also to save manpower and costs. Is the product with the market competitiveness.
