Hi, I'm in Australia and am relatively new to CNC, but have done some cool stuff making model aircraft moulds with my machine. It's a 3 axis mill, with a high speed spindle of min 6000rpm max 24000rpm.
I regularly have to profile out the outside borders of moulds as the final step. They can be up to 45mm thick, and made of Corian, plywood layers laminated with fibreglass, or MDF. I learnt through experience that my standard cutters start to overheat badly in these deep slots, so I'd like to get some cutters for the purpose. I was advised to get cutters with longer flute length and the only ones I could get were HSS and they only lasted a few minutes.
My question is, where would you buy decent quality 6 or 8mm carbide cutters with say 45mm flute length?
Or a special profiling cutter with a shank that's slightly narrower than the cutting diameter?
Thanks,
Andrew
