    Haas VMC Spindle Bearings

    I have a Haas VF3YT50. The spindle has a growling noise and feel coming from it. Does any have an exploded view of the spindle cartridge or good information about the spindle. It appears my bearings are bad and I am having difficulties getting good support from my HFO. Is there a good after market rebuilder for these spindles?

    Thanks for your help....

    Before you rebuild the spindle just want to let you know that my noisy, growling spindle was cured by replacing the MOCON board.

    Thanks for the info Nakedanvil. I have removed the belt from the spindle and the noise is still there. That should eliminate every thing electronic.
    Thanks again,

    Thanks again,
    Wouldn't that also eliminate your spindle as the source of the problem?

    I have taken that spindle apart and when I print it I will post a internal breakdown with bearing numbers.

    Spindle issues

    Our '93 VF3 just died with a spindle failure. Running almost nothing but aluminum for all its life and without any new noises or change to finish, the spindle just slowed and stopped. We've disconnected the transmission and the spindle will turn with some persuasion but cogs. Our Haas guy tells us we need to spend the $4200 + another $1000 for installation. After being beat up badly by the economy - this isn't an expense we need right now. If you come up with a DIY for this or come up with another link - PLEASE post it.

    The good news is it won't be $4200. You get half that credited back to you when they take the old one with them.

    Hello,

    I am Yogesh, from Capital Engg, India,
    There are various reasons for noise in the spindle:

    a) Bearings are gone
    b) Bearing seats (where bearings are mounted may be sleeve or shaft) are gone.
    c) Spindle shaft is unbalance.

    Haas Spindles are Shrink fitted, so it is very difficult for one to dismantle and change the bearings of your own.

    You may let us knw the dimensions of the spindle, and we can manufacture spindle exactly same as it was the original, in very low prices. you can Email the drawing or dimensions of the spindle at cec@sify.com, and we will send the Offer

    VF3 Spindle rebuild

    After removing the spindle and reading all the posts, we've decided to have the spindle rebuilt and returned ready to install. A former Haas tech connected us with a place in So. Cal. that will charge $2200 including 6-mo warranty, which is a good deal less $$$ than what I've found other places. I'll post a follow-up - good or bad - after we have the machine running again.
    btw Cory: actual price from authorized Haas is around $4500 (they keep the core) and no warranty unless they install - another $700+/-. This is not too bad in normal times, but $3000 is a pretty important savings these days.

    I've had my gearbox replaced twice and both times they deduct 50% of the cost of the new part when they take the old one with them. They told me the same applies to spindles as well.

    If you change out your spindle you may need to "Burn It In" you will also need to check for tram. I could locate our "Burn" program if you would like.

    What are you refering to when you say "burn it in". Is this a long gentle acceleration to warm up the spindle, or something aggressive (like it sounds)?
