We will find that many magnets have holes on them, and the common shapes are rectangle, square, circle, arc, etc. Some of them have 1 hole, some have 2 holes, or even more, so how are these holes processed?
The holes on the neodymium magnets are generally processed when they are not magnetized. If they are magnetic, they need to be demagnetized before drilling.
What machine is used to punch holes in neodymium?
Like the general magnet manufacturers, they usually use the bench drilling machine, which mainly drill (punch), enlarge and lower the hole of the magnet. Of course, if you want to drill holes yourself, you can also try using a vibrating diamond grinding wheel drill.
What are the types of magnet punching?Usually, the magnets are mainly punched with countersunk holes, and there are also straight holes. The processing method of the countersunk hole ring magnet is to drill or drill again after slicing, and the processing technology is more demanding.
Our company (Courage) undertakes various processing and customization of perforated neodymium magnets, biased hole strong magnets, side perforated magnets, and high-precision countersunk hole magnets. If you need it, please contact us.
