JBO,
Well I really don't machine like the old days..IE: heavy slow cuts. I machine fast and light so the rigid part never payed much attention too. With todays new Inserts and grades and all this is in my opinion the way to work.
I don't really do what would be termed unattended in that I don't have pallet machines..I have set a part up and let it run into the night with no one here..but not my normal practice as most of my cycle times are not that long..under 1 hour normally.
As for running 8-10 hours we run that just not on one part..and not normally at top speed..we would run them at say 6500 to 7200 for an hour or so straight...sounds like you are doing molds or electrodes... one thing to note, Haas cool the spindles with the coolant used for the tools..althought I think you can get a spindle chiller too...so if you are running dry you would need to address this..you can plumb the coolant so it does not enter the enclosure and still use it to cool the spindle,,,
