    Oh, you just need to translate the noise into Chinese so that they can understand it!

    For sure, perhaps it's just out of tune :

    Hi cropwell!

    That made me laugh.


    On topic:
    We can start a campaign if the shop dont want to help you.

    It sounds like they try to play stupid and hope you loose interest.

    I must say i have had good service when i had a problem with my bearing blocks.

    Must be said i also announced me being on this forum.



    Grtz Bert.

    Thank you all for your involvement, the fact that it's one of the bigger seller disappointed me. I had a very good experience with the BST Automation after sale service and thought it will be the same... Thanks again. News from my old friend, just one sentence: "The sound of grease".
    The sound of 'missing' grease for me...

    Some news: solded as a 4 bearings unit, well well well.

    Yeah. What you're missing is that there's probably only four ball bearings in that!

  8. #218
    Yes, four square balls .

    Just listened to the video and I have heard people talk about the settling of grease in bearings (clough42 channel where he showed a very nice spindle with PDB made in the US that had a small amount of chatter). So my own view is that it can be a cause but this sounds too loud.

    My bet would be the bearings are skipping around as the noise is quite loud. Are the bearings a press or good fit on the spindle shaft and housing? Wonder if they are machined out of spec?

    Do you have tools to measure the fits ?

    If the bearings spin nicely in your hand try loctiting them place if you are looking to try and repair it yourself.

    I've been looking for the difinitive "How to dissassemble, re-grease and reassemble your 2.2Kw water cooled spindle without breaking it" thread but haven't found it. I'm sure a list of key pointers to what you must and must not do and what tools you must have before you begin would be much appreciated by many readers contemplating a check of their bearings. Is this something the pro users do regularly?
