Your CNC Options

Retrofit kits—Any existing Sherline machine can have stepper motor mounts added in place of the handwheels. Complete retrofits with computer and motors are available as well.

CNC-Ready—You can order any new Sherline machine with stepper motor mounts installed. You add the stepper motors, controls, software, computer, and other components to turn it into a complete CNC system.

Complete CNC—You can now buy a complete turnkey system with everything you need to get started. You can also order all our standard accessory packages. For example, you could order a CNC mill with the “A” accessory package, or you could order a complete shop package including lathe, mill and rotary table all fitted with stepper motor mounts, stepper motors, computer, drivers, and all the tooling and accessories.

Complete Ball Screw Mills—Our ball screw mills can be purchased with 12″, 14″, or 18″ bases, and come in CNC-ready or full CNC configurations. You can also retrofit your current CNC mill to a ball screw machine. Low friction in ball screws yields high mechanical efficiency compared to other leadscrew alternatives, and efficiencies can range from 70% to 95%.

Key upgrade parts for these ball screw mills include: Ball leadscrews, High-torque stepper-motor couplings, Ball screw mill saddle (nickel/Teflon plated) for the X/Y-axes, Vertical milling column saddle for ball screws, Column saddle Z-axis ball nut mount for the Z-axis, Linux CNC program disc designed specifically for ball screws.

CNC Features

  • Utilizes industry-standard g- and m-codes that you write yourself or generate from a CAD/CAM program (not included) that writes G-code.
  • Features powerful NEMA 23 size, 136 oz-in, dual shaft stepper motors.
  • Capable of accuracy to 0.001″ (0.01 mm) or better.
  • Tool offsets—Enter the tool diameter in the “tools” table, and the computer calculates how far to offset the tool path, so the side of the tool cuts the desired path.
  • Accepts inch or metric dimensions using G20, G21.
  • Instructions by Joe Martin—the most practical, concise and down-to-earth you will find on the subject of CNC.
  • Priced for the hobbyist but suitable for running small prototype or limited production work.
  • One year warranty for home (non-production) use.
