Hi all, I'm after some advice or info, I have a Ø580 x 140 Flame cut mild steel bit of metal. I'm turning it on a Mazak quick turn 400-ii using an iscar 6025 CNMG for the roughing 0.8 rad (tried 907 grade too, doesn't last as long)and the flame cut edges are wearing the tips out rather fast.
The first cut is around a 2-3 mm depth of cut to get under the skin at 160mm/min at a .35 feed rate, are there any more suitable tips available to deal with the flame cut edges.
Thanks
