    Thanks in advance.
    You did not say what kind of machine this is on

    If it is a quality machine, then no you would not need it, you would need to block the hole though, any chips getting will seize up the quill

    For any cheap import machines, you may need it to take up the slop in the quill, as most have too much clearance between the quill and the housing, removing the handle would be a good idea, if you have it to tight that could be a problem as well

    Thanks for your reply.

    It's a Manford Super Precision knee mill (Taiwan), converted to CNC. They claim TIR at the spindle taper is <.00012, so it should be a tight machine.

    The spindle run out spec, has nothing to do with the quill and Housing clearance, but these machines should be no as loose as some, I would not take it out, just remove the locking handle

    Looks like what you have is the same machine as the Acer there are many that are just rebranded

    Thanks for your reply, once again.

    I was under the impression that the spindle runs in the quill, so wouldn't a tight spindle = a tight quill?

    Keep in mind that the quill is held in place (in part) by the cnc quill drive kit.

    I appreciate your replies, this is new ground for me.

    The manufacturer (Manford) took out the quill lock when installing the quill drive, so what I'm specifically asking is;
    Do I need to purchase and install one?

    Not really what you first asked, if the retro fitter removed it then there would be no need for it, they are protecting the quill by removing it, as if it go locked up to tight it would cause damage, I would make sure the hole is blocked off, or chips will get in there and cause more damage than if it still had the quill lock in place

    The spindle runs in the quill yes, but the quill runs in the Head main housing, this is were the quill has to be a good fit, the lock is not related to the spindle in any way, the lock is related only to the Quill and main Head Housing
