Has anybody ever seen a HP and torque curve for these machines.
To me it seams that the Hi Feed mill would be the better route, You could tailor the doc. and ipm. to keep your spindle load in check. But still keep your MRR up.
We have a bridge mill at work that runs a 6" Tungaloy Hi Feed mill and they have run out of power trying to push it to the max feed rate and that's with a 50 hp motor!! It's pretty cool watching the chips fly on that machine.
