Our Ball Screw milling machines come with all-new saddles developed for the ball screws. The ball screws are rolled with a BSH nut and are 10 mm in diameter with a 2 mm lead. The ball screw machines are available only in CNC configurations. CNC-ready ball screw mills are not turn-key machines and cannot be used until stepper motors have been installed.

Sherline Ball Screw milling machines can cut metal, wood, or plastic and come in two different sizes: tabletop mills (12″ bases) 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 mini-mills are made in the USA, and our customer service is second to none. Although our mills are small, they can produce high-quality precision parts. These Ball Screw mills are desktop milling machines with full-size machine precision and accuracy.
