Retrofit of Hurco KM-1/Bridgeport CNC Mill (Advice Wanted) My wife started up a machine shop a few months ago with some manual machines (mill, lathe, surface grinder). A few weeks ago we picked up our latest addition: an old Hurco KM-1 CNC mill, which is a Bridgeport Series 1 with ball screws, a Kwik Switch 200 taper, and servo motors.

Ball screws are required with a CNC mill. While CNC control is on the servo or stepper holds the screws tight all the time. In manual though the ball screws will move (creep) when not intended. The original acme screw has more hold on the non moving axis. So if you have ball screws you need to always tighten down the non moving axis.
