    spindle head BT40

    It's more a mechanical question ragrding a spindle itself.
    Are these below worth bothering with / any good?.
    Considering swapping my benchtop milling machines head for one.

    Will be ran with a 1.8kw servo.
    Pulley setup will deliver max 6000rpm.
    Plan to build 10 tool ATC for it in future.

    Will it work fine?.

    Re: spindle head BT40

    Firs just by looking at a bearing specs (not a precision bearing) tells a lot.
    If budget is low maybe you can swap the bearings whit high precision later if everything else is made well (?).
