Hey guys, today im going to be running a 3/4" inserted ballmill in mild steel.
All i have to do is basically slot a 12" long bar with the 3/4" ballmill to get a 3/8 radius. ive been fudging the numbers around and im just not sure what good feeds and speeds/stepdowns would be good to use here.
i have it at 400sfm .01 chipload, .02 step down. think it said 15 ,minutes which seems slow to me.. anyone have a better formula to use?
