How to prevent fracture in NdFeB drilling?

There are three factors that affect the fracture of NdFeB drilling: machine tool, cutting tool and high temperature.
For medium hole NdFeB magnets with inner hole less than 8mm, the most commonly used one is instrument lathe. Bench drill is a necessary lathe for drilling some tiles. In addition, we should do a good job in the fixture of the product and fix the product. The holer is a lathe used for medium hole NdFeB magnet products with inner hole more than 8mm.
Alloy tool is a necessary tool for drilling. It is usually used in the instrument lathe and bench drill. If it is not a special alloy tool, the NdFeB drilling will break.
In addition, the high temperature produced by the magnet and cutting tool in the process of processing needs water and oil to cool down, otherwise the drilling fracture of NdFeB magnet will occur.
Professional things to professional people to do, we do not recommend customers to punch their own magnets.
