I have a setup that is working well, but the tool is lasting VERY long so I'm ready to trade off life for higher MRR.
(I can wreck some things in the pursuit of a long term improvement.)
Specs:
HAAS ST25Y lathe
BENZ radial live tool, ER32 collet
High flow flood coolant mixed at 10%
ISCAR FINISHRED, 1/2 endmill, 1/16 cham
4 flute (2 rough + 2 finish), 1" cutter
1.4" total stickout
STOCK:
-3" tube, 3/8 wall, 304SS annealed
-no mill scale (removed in prior step)
START CONDITION: 5/8 through hole
OPERATION:
ROUND COUNTERBORE POCKET
1.698" DIA x 0.300 DEEP
O-ring face on floor of pocket
METHODOLOGY:
Spiral passes with constant RDOC
CURRENT PARAMETERS:
-375 SFM
-RDOC 0.1" (20%)
-Feed 0.0035 IPR
-Finish: flawless / o-ring ready
CURRENT TOOL LIFE:
Still waiting. Hundreds of holes no change.
No signs of heat issues.
No chipping
This is obviously not as rigid as a heavy mill, but it's really solid and can certainly take more load.
To get higher MRR, what should I vary?
What would a high efficiency mill CAM suggest?
Thanks.
