12″ CNC-Ready Mill

Our CNC-ready tabletop mill is ideal for customers seeking a compact CNC milling solution for producing small, precision parts. Made in the USA and backed by exceptional customer service, this mill offers full-size machine accuracy in a desktop footprint. Despite its size, it’s capable of cutting wood, plastic, aluminum, and even steel with impressive rigidity and precision.

CNC-ready mills come with factory-installed stepper motor mounts in place of handwheels and are ready for you to add your own stepper motors and CNC controls. Please note: these are not turn-key systems and cannot be operated until motors and controls are installed. CNC-ready machines do not include stepper motors, a computer, or CNC software.

Sherline recommends dual-shaft stepper motors so manual control is still possible using the included handwheels, which mount to the rear shaft once the motors are installed. Sherline also offers high-quality stepper motors and CNC components to complete your system.

Additionally, you can explore various aftermarket suppliers for compatible motors, drivers, and software. Visit our CNC Dealers page for a list of suppliers and links to their websites.

Note on Ordering a Metric Mill – Most Sherline cutting tool, such as center drills, are offered in fractional sizes. If you opt for a metric machine with metric collets or holders, you’ll need to order compatible fractional-size holders to use these tools effectively.

Standard Equipment for the 12″ Deluxe Tabletop Mill
  • A powerful 90V DC motor with electronic speed controller
  • 12″ base with laser-engraved scales
  • Brass leadscrew cover that keeps chips off the rear of the Y-axis leadscrew
  • 2.75″ (70 mm) x 13.0″ (330 mm) table with laser-engraved scales and two T-slots
  • 1.235″ headstock spacer block
  • Resettable, zero-adjustable handwheels that can be mounted to the end of the stepper motors to maintain manual control when needed:
    • (2) 2″ (51 mm) handwheels on X- and Y-axes
    • (1) 2-1/2″ (63 mm) handwheel on Z-axis
    • All with laser-engraved aluminum collars
    • NOTE: CNC-ready machines cannot be operated manually unless double-shaft stepper motors are installed.
  • ¼” Drill Chuck w/ key, #1 Morse arbor with drawbolt
  • Pulleys, drive belt, three hexagonal keys, spindle bars, gib removal tool, eight-foot three-wire power cord, and instruction manual
  • Oil reservoirs on the X/Y axes and the Z axis help keep critical parts lubricated. These were initially developed for CNC machines that run constantly for hours on end but can benefit manual machines as well
