Can neodymium iron boron strong magnet drill holes? A lot of people don't know very well. Today, carrich told you whether the magnet (NdFeB) can be punched.


First of all, we can tell you that the neodymium iron boron strong magnet can be drilled. If the strong magnet already has magnetic force, demagnetize it with high temperature under professional mechanical operation, drill it with milling cutter at low speed, and then magnetize it again after the finished product's appearance specifications are manufactured. It is usually made into cylinder or square cylinder magnet.


What machine does neodymium iron boron punch with?


Like general magnet manufacturers, they usually use bench drilling machine, which mainly drill (punch), enlarge and ream the magnet. Of course, if you want to drill by yourself, you can also try to use vibration diamond grinding bit.


What are the types of neodymium magnet drilling?


In general, the magnetic drilling is mainly for counterbore and also for straight hole. The processing method of the countersunk hole ring magnet is to cut or drill again after the slice processing, and the processing technology requirements are quite exquisite.
