Hey guys:
I've got a little problem. I'm trying to get the most life out of my 5/8" insert cutter (Mil-Tec). I'm using the largest radius they offer. I'm pocketing 1018 steel. (.194" deep). I've tried running dry, coolant, but it's not directly on the inserts. I was cutting .0625" depths at 8500 rpm & 105 ipm.
I'm down to 7500 rpm .045" depths and 90 ipm.
I'm helical plunging at 12 ipm. If I run it dry after maybe 6 or 7 parts, i'll get a spark show during the helical plunge. I can't run more than maybe 19 parts total. This is a piece of steel that is 6" long x 2.75" wide.
Do I take .025" depths of cut? They won't let me order inserts. I got this tool for free. I have to wait until monday for the rep. I'll hook him up on some items here for some tooling. I'm using the recommended grade insert for the material.
Any and all info is greatly appreciated.
Thanks,
