Under this contents, we introduce each kind of magnetic material more intuitive. We know that any magnetic material must work for people as a certain shape of the magnet. Base on different application requirement, these types of magnets often made out -- disc magnets/magnet discs, block magnets/rectangle magnets/ square magnets/magnet blocks, ring magnets/magnetic rings , round magnets/cylinder magnets/rod magnets. Above shapes are basic shape for each kind of magnetic material.Here we just introduce some common shapes of permanent magnets, and mainly for neodymium magnets. For sintered neodymium magnets, because of the high machinability, it can be machined into different shapes and very wide size range for each shape. Besides of the mentioned types, neodymium magnets can be machined into some special types, for example, countersunk magnets, sphere magnets/magnetic balls, cone magnets, arc magnets, segment magnets, convex magnets.For practical application, the shape and property ofstrong magnetare diversified, different types magnets need different machine methods, the common processing methods are cutting, drilling, grinding.For sintered NdFeB magnets, the surface requires smooth and high accuracy, grinding machine needed for the surface of rough delivered magnets. Common used grinding machine method for blockNdFeB magnetsare plane grinding, two end face grinding, inner circle grinding, out circle grinding. Cylinder magnets adopt coreless grinding and two end plane grinding. Irregular magnets(arc magnets and segment magnets) adopt multi-station grinding.Estimate a magnets qualified or not, not only need the magnetic property qualified, magnets size and tolerance also affect the performance and application of a magnet. The tolerance accuracy decided by the machine ability of a factory. The machining equipment keeps updated as market needs. Efficient devices and automation trend of industrial processing, not only meet the need of increasing magnets accuracy but also save the manpower and cost. Make the magnets products have more market competitive power.
