Ball Screw Kit for Bridgeport mills. Ball Screw - How it works. Ball …
Ball screws are very similar to recirculating ball bearing systems, using the same rolling properties of ball bearings to convert the motion. Ball bearings roll inside of special grooves cut into the ball screw and nut, allowing for lower friction (and thus a smaller motor), higher precision, and the ability to run under high cycle conditions. ...

Sherline Ball Screw milling machines can cut metal, wood, or plastic and come in two different sizes: tabletop mills (12" base) and benchtop mills (14" and 18" bases). All Ball Screw milling machines only come in a metric pitch, so the numeric graduations on the handwheel dials are 2 mm per revolution and .02 mm per line. All our mills are made in …
This covers most of the parts needed to build the mill, except the stepper motors, drivers, power supply and the controller. I intentionally decided to punt on this while doing some more research. My total out of pocket cost so far is as follows: Missing cast iron parts - $226; Ball screws and axial bearings - $130; Spindle bearings - $96
