NdFeB Magnet Round Shaped with Countersunk Hole

Neodymium magnets
One of the most core materials in the modern industry is the neodymium magnet. That means the neodymium magnet has been treated as the hero in the modern industries.The neodymium magnet is also known as ndfeb magnet. It is small size while preserves the strongest magnetic power. Neodym magnet is composed of rare earth element neodymium and ferro magnetic material iron and boron. Ndfeb is with bad machanical properties and chamical stability.Usually they are with surface plating to prevent corrosion.
Neodymium magnet is the third- generation rare earth permanent magnet. It is made from the alloy of neodymium, iron, boron etc to form the Nd2Fe14B crystalline structure. NdFeB magnet is the strongest magnets compared with SmCo, AlNiCo and Ferrite magnets. Neodymium magnets are extensively used in motors, electronics, wind generation, air conditioner, pumps and magnetic assemblies.
Main Manufacturing process of ndfeb magnets  

1.Pressing ndfeb garins: pressing process was operated in strong magnetic environment. 
2.Sintering of ndfeb blocks: sintering was processed in a vacuum furnace.
3.Wire cut: ndfeb magnet are fragile materials,usually specified dimensions was required, genneral cutting process could not reach the standard of sizes,usually cutting process had operated in wire cut machines. 
4.Grinding process: Grinding process: To reach the tolerance, a diamond polish tool is needed. 
5.Plating: Neodymium magnets had been treated with electrical plating,otherwise it will rust in the air. Platings that have been successfully applied to neodymium magnets are epoxy plating,nickel plating,NICUNI plating,zinc palting and even silver plating and gold plating. 
6.Magnetization:the procedure are processed with magnetization machine which have a magnetic feild ranged from 2~100 koe.
