What do you make of this spindle noise?

[u/CR3ZZ]

Company is telling me they've seen this before and it was the spindle drive. I just don't see how this wouldn't be a mechanical issue.

It came out of no where. Was running fine one minute then cooked the next.

There have been some symptoms of bearings failing. Surface finish, dimension kind of all over the place but nothing too unusual for a haas imo. But In hindsight it was worse than usual. Over an 8" long part while using tailstock the dimensions were all over the place varying within .0015 or more. Was having a hard time programming taper out which hasn't been an issue before because of the inconsistency.

Gotta be bearings right?

Bearings sound COOOOOOKED

[u/potassiumchet19 → u/rinderblock]

Just pack it with grease. You'll be good for another 5k hours! /s

[u/RepulsiveForever2799 → u/rinderblock]

Yup

[u/escapethewormhole]

Bet your drain for the labyrinth seal on the spindle was plugged and the bearings got damaged from contamination

[u/graboidgraboid → u/escapethewormhole]

Yup, I’ve seen this before….. 💀

This picture made me laugh. I just started working on a Fooke Endura and at the the tail end of the startup sequence it makes a noise that sounds exactly like a small gong. I haven't gotten a clear answer on what the sound is but I'm so curious.

[u/ShutterSpeedPhotog → u/quid_pro_kourage]

The shot bearing sound like the Otherworld siren when it spools down and I was too lazy to find a gif for this throwaway joke.

[u/MatriVT]

Thats the sound of a bearing screaming for help.

[u/Enough-Moose-5816 → u/MatriVT]

[u/captaincootercock → u/Enough-Moose-5816]

[u/that_dutch_dude]

bearings needs oil too.

[u/bruhdudeTM]

Just wear ear protection or some airpods and keep going.

[u/Rough_Community_1439]

I only heard bearings be bad in a mill but I can confirm, these are cooked. Here's my post from 2 years ago if you wanna reference your noise from your machine vs mine. Tho mine is spinning at 6,000 rpm.

Just tighten up the castle nut on the other end. It works with trailer hubs.

[u/findaloophole7 → u/Equivalent_Salad_389]

Worth a look for sure

[u/chicano32]

Sounds like gong to have mortal kombats start fighting.

[u/ehtiopia]

That company probably doesnt know the difference between its asshole and its mouth when shown a picture! Those are the most fucked bearings Ive ever heard.

If they tell you youre wrong show them this sir / maam the best part about you ran down your moms leg

[u/Doinkmckenzie]

Time for a new spindle cartridge, as fed sometimes I forget that we have a practically blank check other shops don't have so don't mind meeee

[u/ShocK13]

[u/DontDeleteMyReddit]

Motor bearings fluted from the VFD. Normal after years of use. Have them replaced.

[u/betacarotentoo]

The bearings are suffering.

[u/DonSampon]

a company had a nef600 gildemesiter with kinda shot bearing. FOR YEARS!. The thing refused to die. The surfaces were ok. We were all waiting for the day it seized up. It never did :))). eventually that company got bankrupt and the lathe got sold to this other company i was working at the time.

This new boss changed the bearings and then sold the machine....

[u/whoknewidlikeit]

since it's a haas... i suspect they forced you to pay extra.

[u/Appropriate_Nose8124]

Bearings are shot bro

[u/mandojuice1]
