Machining process of neodymium iron boron magnet

2023-12-18

Tell everyone about the machining of neodymium iron boron magnets. In order to cut the magnets neatly, a magnet slicing knife is usually used, but the magnet must be fixed first, and the size of the slicing machine must be adjusted before cutting.

1. There are generally three methods for slicing magnets: electrical discharge machining, laser machining, and grinding.

2. In practical applications, the shape and performance of NdFeB magnets are different, such as: circle, cylinder, ring, round counterbore, square, square counterbore, tile, trapezoid, groove and irregular shape Wait. The size, performance, tolerance value and magnetization method of each magnet with a different shape of the cut magnet block are different.

3. In the production process, it is difficult to mold the magnet at one time, all of which have to go through multiple processes. The general production process of Tongli Magnetics is to produce large (large-size) blanks, sinter them, smelt them, and then perform flat grinding through mechanical processing (including cutting, drilling, and chamfering), surface electroplating treatment, and then magnetizing treatment. It is best to conduct dimensional accuracy, surface quality and salt spray tests on products, packaging and transportation. Micro NdFeB Magnet is your good choice.
