    Default mazak qt20n z axis ball screw

    i am wanting to check the ball screw to see if it is in a bind or something bound up possibly in a bearing will i need to take the screw completly out to check. The ball track looks good but wanting to check and see if there is a lot of resistance .

    thanks

    the bearing pack on the headstock end of those things used to rust up and bind up.
    you can take the whole setup out towards the servo without removing the screw
