So did they charge a core charge for the old spindle?
Do you have to ship it back?
If not, you have a golden chance to see what went wrong and possibly rebuild it yourself or someone locally and have spare.

That is about what I gathered from reading about spindles and repairs. Thanks for the confirmation.
I would call C&M spindle in Oregon .. there great to deal with and way cheaper than buying a new spindle ,, they did a friends fadal for $2,200 a couple years ago ,, i`m thinking a Haas should be around that price.
Well the new spindle was installed a week ago. I had a chance to make several parts this week with it. I have no doubt now that the original spindle wasn’t right from day one. But since I had nothing to compare it two I didn’t recognize the issue. The new spindle is way, way quieter than the old one ever was. Not by a little but by a lot. Also the new spindle runs at a much lower spindle load when free spinning with just a tool in the holder. With the old one the spindle load ran about 12 to 14% at 4000 rpm. The new spindle runs about 4 or 5% at 4000. Also with the old spindle if I ran a very long cycle (40 mins or so) the tool would get stuck. Sometimes it wouldn’t come out without a very large bang at the tool changer. I had actually posted on here asking what to do about that because it was rocking the tool changer pretty hard and a few times the machine faulted out because it couldn’t pull the tool out. I have top quality holders so I knew it wasn’t those. Now I think it was because the spindle was heating up with use. Anyway you all were right I should have just changed it myself. The tech that came to do the job didn’t use a single tool that I didn’t already have in my shop. No special alignment procedure after the install. Just unbolt the old one and bolt in the new one. Total cost was $5900. But what really sucks is that Haas was no help at all. I couldn’t even get them to listen to me. By that I mean they wouldn’t stand behind a spindle that failed after only 229 cutting hours. Nearly $6000 for 229 hours of use is pretty miserable performance.
Break in program running.
is this the 2008 tm-1 you have at the bottom of all your posts? did you check with C&M spindle ?
Belts too tight?
The extreme runout vibrations can attenuate through the spindle and have negative effects on the sealed spindle motor bearings.
Observe the operation of the spindle at increments of rpm change per 500. Do this CW & CCW. We have a mill that is limited to 2500. Anything higher and is sings.
Be sure you’re adding the correct lubricant weekly at the oiling port located at the top of motor housing.
*All resources checked and cross referencing done for acceptable feed rate combined with tool, material and rpms. Yet slowing the rpm was the right answer even though it went against all ink on paper guidance.
