'warming up'/lubing spindle

noob here.

i have a 96 VF6

was watching vids and saw a rec that on at least certain machines (TM1 in this case) if the machine sits you need to cycle the spindle to get the lube up to the bearings. is this something i need to think about?

Yes. Every machine tool should go through a simple warm up cycle before you slam it into overdrive. Just make a simple program that ramps the spindle up by 1000 RPM every 2 minutes or so. Maybe turn on the coolant and let that mix up. Possibly move the X and Y around.

I think Haas has a warm up program you can copy. Or, I'm sure someone can post one here.

This is what is in my 06 VF2SS:

%
O02020 (Spindle Warm-up)
(This program should be run prior to)
(machine use if machine has been idle)
(for more than 4 days.)
(Cycle time: 20-minutes.)
(This program can be used for all)
(spindle types and may be used daily)
(for spindle warm-up prior to high)
(speed spindle use. Adjust spindle)
(speed override depending on maximum)
(spindle speed of machine: Set)
(override at 50% for 5,000 rpm)
(machines, set at 100% for 7,500)
(& 10,000 rpm machines, and set at)
(150% for 15,000 rpm machines.)
(9-21-99)
S500 M04
G04 P200.
S1000 M03
G04 P200.
S2500 M04
G04 P200.
S5000 M03

That looks exactly like the TM-1 warmup, except the latter stops at S4000, and no text about fooling with the override.

if low rpm not as fussy
.
but going from cold machine to 10,000 rpm many machines dont like. of course a router does it cutting wood but many cnc you need time for temperature to stabilize so parts cut more repeatable as machine changes size as its temperature changes

I was told by a very good HAAS tech that the reason to "warm up" a HAAS spindle is actually to clear oil that has settled in the bottom bearing.
He said if the bottom bearing is flooded with oil, and you run it at high RPM, it will over-heat very rapidly.
Since these bearings are oil/air mist cooled and lubricated, the pooled oil needs cleared.
I am sure there is also some temperature stabilization going on that is important. But, he really emphasized getting the pooled oil cleared.
This was about 7 years ago before I had my own machines. And, the tech was replacing a spindle when he told me this.
He also told me, all you really need to do to "warm up" a spindle is turn it on @ 1500rpm for about 15 minutes. FWIW
