What surface speeds is everyone running on tialn coated mills? Not much info to find on the net that i can find as far as the SFM. Getting into high speed milling. I know it has alot to do with metal type and hardness but just in general whats working for you.
I am currently milling around 600SFM with a pretty heavy chipload and getting about 30 minutes of cutting time from carbide inserts tialn coated. Id like to know where the speed limit is before tool life generally starts falling off fast.
