I've bought a pack of 10 alnico polepiece magnets for electric guitar pickups (but in this case i'm trying to make an electric banjo). Being the clever sod I am I bought them oversized figuring I could easily machine them to length. The magnets came with a wee magnet safety pamphlet that said that they were difficult to machine without specialist tooling. I've had a look through google and haven't been able to find anything beyond various companie saying 'yes we can machine it' in the sales pitch. I'm just wondering if anyone's had any experience with this. 10 magnets are exactly the amount I need so I don't want to try experimenting. I suppose there's also the concern with toxicty if it gets all dusty while machined. |

I have tried to machine magnets of varying type.. And sorry to say if you dont have access to diamond cutting tools and a high pressure flood cooler those will not be cut with quality. I tried HSS, indexed tools of varying quality and well they have tendency to explode and not taking vibrations well.. Sintered little buggers.. |

I've got one of those diamond tile saws hanging around somewhere. Would there be any hope of grinding them to length with that? |

How about a bench tile saw with diamond blade? |
