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.

This 12″ XYZ base is the same base used in our 5400-series mill, but has been modified for use with ball screws. It has a 12″ base with stepper motor mounts  installed on the X-, Y- and Z-axes ready for the installation of stepper motors, and laser engraved table and base. (Stepper motors not included, see the STEPPER MOTOR page.)

*NOTE: CNC-ready machines cannot be operated manually until stepper motors are installed.

Standard equipment for the XYZ base:

  • 12″ Mill Base
  • Electroless nickel/Teflon coated mill saddle
  • 11″ Column Bed. Option to upgrade to 15″ Extended Column with nickel/Teflon plating
  • 13″ Mill Table
  • Stepper-motor mounts with high-torque couplings
  • The handwheels are included and can be mounted to the end of the stepper motors to maintain manual control when needed.* 2-1/2″ (63mm) adjustable “zero” handwheel on the Z-axis and 2″ (51mm) adjustable “zero” handwheels on the X- and Y-axes. Each handwheel has laser engraved aluminum handwheel collars
  • Oil reservoirs on the X/Y axes and the Z-axis to help keep critical parts lubricated.
  • Brass leadscrew cover that keeps chips off the rear of the Y-axis leadscrew
  • Accordion way cover
  • Travel: X=8.65″ (220 mm), Y= 5.0″ (127 mm), Z=6.25″ (159 mm)
