Magnetization is an essential process in the production of magnetic steel. If a magnet is not magnetized, it will not have magnetism and will lose its basic function as a permanent magnet material. As a three-dimensional workpiece, magnetic steel varies in shape and size. How to magnetize magnetic steel? Is the magnetization effect the same in different directions? Today we will talk about these issues.

Magnetic materials are divided into two categories: isotropic magnets and anisotropic magnets:
Isotropic magnets have the same magnetic properties in any direction and can be magnetized arbitrarily; The magnetic properties of anisotropic magnets vary in different directions, and the direction in which they can achieve optimal magnetic performance is called the orientation direction of the magnet.
The common anisotropic magnets are hard magnetic materials such as sintered neodymium iron boron and sintered samarium cobalt.

Sintered neodymium iron boron is prepared by powder metallurgy, which has high hardness, brittleness, and is prone to fracture; And the heat release, corrosion, and defects during the processing can all cause damage to the magnetic properties, so it is necessary to choose the appropriate processing method based on these characteristics. At present, sintering neodymium iron boron machining is mainly based on traditional cutting, grinding, chamfering, drilling, etc., in addition to electric discharge cutting, laser processing, ultrasonic processing and other methods.
