I am having some issues with a 5/8" endmill tending to pull out of the holder on my live tool lathe.
I am stuck with using ER32 collets to hold anything in a live tool on the BMT 65 Turret, so I cant simply get a better holder for milling.
Currently taking .025" Radial DOC at 3550 RPM (580 SFM)roughing at 150 IPM climb milling. Material is 1045 Steel. Im making round stock square basically. The max cut depth axially is 1.8" stepping up each pass as I cut off the radius of the stock making a flat side.
When assembling the tool into the holder, I am cleaning both the collet and tool shank with a cleaner (basically brake clean spray) and tightening the nut as best I can using a cheater bar, and I still have occasional tool pull-outs, especially when the cutter starts to dull.
Not all that surprising, but if the tool pulls out and falls into the bottom of the lathe, it will definitely chip the tool, and I am using a fancy, way too expensive, tool from Sandvik. I need to eliminate the pull-out issue.
Another thing Ive noticed is after running a single flat on a part, my live tool holder is quite hot. I cant imagine the heat is good for the tool holder.
Any help is appreciated.
