    Hmm, that's nice but could be a problem long term as you wont notice if the thread or something starts seizing up. The impact driver will probably just keep going and potentially cause excessive wear / break something? Just a thought..
    How long until automatic tool changing then?

    i don't see it as going to be a problem as the drawbar is the soft expendable part. As the tapers and threads are hardened steel.

    now you need to mount it on the machine and have a foot switch.

    There are quite a few impact gun drawbar designs kicking around, and I've never seen anybody mention having any major problems with them.

    Biggest issue with using an impact gun, is getting a consistent torque.

    Also, don't rely on the threads in the taper shanks being hard enough not to be damaged by a soft drawbar. I bet if you tried filing them, they'll file down without that much effort.

    Late into this post but converted 4 of these machines now based on the Warco WM16.
    1605 ballscrews all round, 3.1Nm motors all round, direct drive on X and Y 2:1 belt reduction on Z
    42 volts power supply and 542 drivers. If I had to do any more I'd increase the voltage to 70v and use the 80v 7 amp drivers de-rated to suit the motors.

    Could you please link the controler you would use for this mill and a suitable place within the UK to purchase it.

    Thanks
