can you grind magnets

I strongly advise against attempting to grind magnets. Magnets are made of various materials, including rare earth metals, and can generate strong magnetic fields. Grinding or machining magnets can cause them to crack or shatter, which could result in injury or damage to your equipment. Furthermore, the grinding process can also alter their magnetic properties, rendering them useless for their intended purpose.

If you need magnets with specific shapes or sizes, it's best to order them from a reputable supplier who has experience in magnet manufacturing. There are various manufacturing techniques, including sintering, bonding, and injection molding, that can produce magnets with precise dimensions and properties.
