Drilling Neodymium Magnets

However this normally occurs prior to magnetisation of the material.

Drilling neodymium magnets. Ferrite magnets drilling or sawing of ferrite magnets is not recommended. Neodymium magnets have a variety of uses. Neodymium magnets are ten times stronger than ordinary magnets. Other applications include high performance motors brushless dc motors generators magnetic separation magnetic resonance imaging sensors and loudspeakers.

Drilling or machining purposes. After market machining neodymium magnets. Neodymium magnets were initially developed for voice coil motors in computer hard disk drives and this market still accounts for over 50 percent of all neodymium magnets produced. Because magnets are so versatile theyre used in many applications.

If one isnt careful a powerful magnet will quickly crumble or lose. When machining or drilling a neodymium magnet it is possible that the build up of heat may cause it to demagnetize. Usually one only endured as a last resort for prototypes and low quantity projects. Below is a list of best practices for ensuring your magnets will be operational after modification.

Grtard 12 pack h neodymium disc countersunk hole magnets. In this episode we made a neodymium magnet which adheres to wooden surfaces. Green energy both hybrid and electric vehicles employ neodymium magnets as do wind turbines. Thats assuming that you managed to drill the hole without heating up the magnet too much because heating it.

Due to the fragile nature of neodymium magnets after market machining can be a tedious process. Specialists can work with the magnets with specialized diamond tipped tools and. While this is possible under the very best circumstances its extremely difficult to perform correctly. Strong permanent rare earth magnets duration.

Merely drilling a hole in the magnet will cause only a minor loss of magnetic strength due to the loss of material from making the hole. Items such as mechanical watches heart pacemakers crt monitors and televisions credit cards diskettes and other magnetically stored media such as video tapes are all affected by powerful magnets. Keep a safe distance at least 20cm between the magnets and all objects that can be damaged by magnetism. The material is brittle and fragile.

Occasionally however customers come to us wondering if they can expand a magnets capabilities though cutting drilling soldering or welding.
