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. All our standard accessory packages can also be ordered. 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.


  • Utilizes industry standard g- and m-codes that you write yourself or generate from a CAD/CAM program (not included) that generates 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.

FlashCut CNC—Sherline has partnered with FlashCut CNC to offer additional solutions to the application of CNC controls to Sherline lathes and mills. FlashCut CNC Retrofit kits, powered by a compact CNC micro stepping controller, perfectly matched motors and plug-and-play cables, are designed for the entire line of Sherline mills and lathes. These kits are available in many configurations and are compatible with the extensive line of Sherline shop accessories. For the first time, these kits are available for purchase directly through Sherline Products Inc.

FlashCut CNC is the industry leader in powerful, easy-to-use, affordable CNC controls for those who prefer to work within the Windows® operating system using USB connections rather than Sherline’s Linux-based controls and 25-pin parallel port connections, making possible its use with almost any modern Windows PC or laptop. While somewhat more expensive than using Sherline’s Linux based system, FlashCut CNC systems provide machine tool automation from any Windows PC. The USB-powered software and signal generator, capable of 100,000 digital pulses per second, forms the cornerstone of the FlashCut CNC product line. With a simple installation to a stand-alone FlashCut or existing Sherline 8760 driver box, it easily turns a Windows-based PC into a powerful CNC controller. The FlashCut CNC control box also offers additional inputs and outputs for limit switches, digitizing probes and relays if desired. FlashCut also offers options for CNC spindle speed control and threading.

Warranty and technical support services on the Sherline portion of the system are provided by Sherline Products. Service and technical support on the FlashCut CNC components of the system are provided by FlashCut CNC directly.
