    ATC draw bar for BF30/PM30 type of bench mills "BT/ISO30 spindle"

    Just a thought,..
    Is it possible to modify the spindle shaft of this type of mill with drilling quill to take a gripper or ball lock ATC draw bar for stud type 30 taper tool holders (BT/NT/ISO)?

    I believe it is possible to regrind an R8 spindle for BT20, not sure about 30. Then it is just a matter of building the drawbar.

    Most go for TTS though, it's just a lot less messing around. Of course BT20 would be far superior in many cases, TTS is adequate for most of the work you would do on one of the machines as well.

    A well setup TTS drawbar works pretty well, but it certainly can take some work if you are building from scratch like I did.
