Back to XY & XYZ Bases
18″ CNC-Ready XYZ Base w/ Ball Screws
2-3 week lead time
Please note that our ball screws only come in a metric pitch
Purpose of the Sherline Mill XYZ Bases
The Sherline ball screw mills can be purchased without the headstock and motor/speed control. This allows owners of other Sherline machines to swap the headstock and motor/speed control from one machine to the ball screw mill in approximately 60 seconds. This package offers a savings compared to the price of our full ball screw mills.
The Axes of Movement of a Sherline 6858 Ball Screw Mill
The table left/right movement is referred to as the X-axis. The table in/out movement is the Y-axis. Headstock up/down movement is referred to as the Z axis. The headstock can also be rotated on its saddle on Sherline mills (#4), the column ram can be moved in and out (#5), and the Z-axis column can be tilted forward and back (#6).
