Need some advice on feeds & speeds. Using Sandvik CNMG-432 MM, grade 2025. Using their feeds & speeds, I only got 10 minutes of (repeatable) tool life ( 18 pieces, then failure, edge worn away). It's a solid part, no overhang, short tools etc. Using water soluble at 8 percent. The problem is I need to get through a pallet of 128 pieces. Anybody have any better luck with a different grade, or style Sandvik insert? I dropped the speed to 275 SFM, and I'm getting 18 minutes, then same failure. the D.O.C. is .100" , Feed .013 IPR. -- Steve Walker res6nlr2@xxxxxxxxxxxxxxxxx (remove wallet to reply) .
