Carbide Inserts not lasting long, what am I doing wrong?
2016年1月10日 · Put these new inserts in yesterday and while facing off a piece of mild steel, doing 270RPM (the slowest my mill goes), .005 depth of cut, the inserts lasted maybe 5 minutes before the chips turned into dust. So I turned all the inserts to finishes my job, and again maybe 5 mins the chips started to turn into dust.
