CNC Linear Controller with Stepper Motor
This stand-alone controller is fully programmable via its integrated keypad and directly controls the stepper motor to which it is connected. The stepper motor can be applied to any axis of a CNC-Ready Sherline machine.
An 8-pin mini-DIN cable allows multiple controllers to be connected in a “daisy-chain” configuration. Controllers can signal one another to operate in sequence, enabling complex, multi-axis movements without the need for a computer or master CNC controller. The system can also be used alongside existing CNC controllers. Each controller stores two independent programs, with up to 40 operations per program. For each operation, you can define travel distance, direction, feed rate, and whether the sequence pauses or proceeds to the next step.
The linear controller can also be daisy-chained with Sherline’s rotary controller, enabling coordinated rotary and linear motion. This allows users to easily perform advanced operations—such as gear cutting—without requiring CNC programming skills beyond simple keypad inputs.
Included with the CNC Linear Controller:
• Linear controller with keypad

• Power supply

• #23 frame size stepper motor

• Cables

• Complete instructions
Note: To add CNC linear control to an axis on a Sherline machine that does not have a stepper motor mount, see P/N 8850.
Power Supply Compatibility:
The included power supply operates on 110–240 VAC and automatically adjusts for global use (220–240V). Earlier versions of this product shipped with a 110 VAC-only power supply.

Rotary Table Indexer
Sherline has advanced its precision 4" rotary table into the 21st century with the addition of Computer Numerical Control (CNC). This upgrade makes it an ideal solution for clockmakers, gear cutters, and anyone needing to machine intricate radially symmetrical patterns. The CNC rotary table takes the complexity out of repetitive indexing tasks.
Complete, Stand-Alone System
Programming is done entirely through the integrated numeric keypad—no computer required. The system includes everything needed for operation:
• 4" Sherline rotary table with pre-installed stepper motor

• Microprocessor unit with numeric keypad

• 115 VAC power supply (universal 110–240 VAC compatible)

• All required connecting cables
Mounting Options
The rotary table includes clamps and T-nuts for mounting to the T-slots of a Sherline mill table. Additional options allow for flexible positioning:
• Right-Angle Attachment: Holds the table vertically at a 2.7" center height. A matching right-angle tailstock is also available for supporting long workpieces.

• Tilting Angle Table: Allows mounting at any angle from 0° to 90°. At 90°, the center height remains 2.7", compatible with the right-angle tailstock.
Simple, Accurate Operation
Simply enter the steps per revolution (or degrees per step) via the keypad. The table advances precisely to the next position at the press of a button. If needed, previous positions can be recalled instantly.
• Resolution: 28,800 steps per revolution

• Accuracy: ±0.006° per step
This precision allows for accurate machining of gears with odd numbers of teeth, and built-in calculations prevent cumulative errors.
Flexible Integration
This CNC rotary indexer is a complete, stand-alone unit—perfect for complex indexing operations. It can also integrate with other CNC systems:
• Accepts input signals from an external CNC controller

• Sends “completion” signals back to the master controller

• Can be daisy-chained with other units for coordinated actions
For more advanced applications, the rotary table can be linked with Sherline’s linear controller (P/N 8800), enabling seamless combinations of rotary and linear motion—ideal for gear cutting and other multi-axis operations, all without requiring advanced CNC programming knowledge.
Weight Capacity (Continuous Use)
• Horizontal orientation: 50 lbs

• Vertical orientation: 30 lbs

• Vertical rotational torque: 6 ft-lbs (e.g., able to lift a 6 lb. weight 12" from the center)
Note: The table can handle heavier loads if not under continuous use. Refer to the Video tab for practical examples.
Power Supply
The controller power supply operates on 110–240 VAC and automatically adjusts for global use. (Earlier models included a 110 VAC-only power supply.)
Compatibility with Tilting Angle Table (TAT) Limit Switches

CNC Rotary Table with Stepper Motor
A fully integrated 4″ (100 mm) precision rotary table with a built-in NEMA 23 stepper motor and plug-in interface, ready to serve as the A-axis on your Sherline CNC milling setup. Designed for seamless G-code control and radial machining, it supports continuous loads of 50 lbs horizontally, 30 lbs vertically, and delivers approx. 6 ft-lbs of vertical torque. Backlash is held under 0.2° and it achieves roughly 28,800 steps per revolution (~0.006°/step) for high-accuracy indexing.

Stepper Motors
Sherline stepper motors are NEMA 23, dual-shaft motors designed specifically for our CNC mills, lathes, and rotary tables.
Both the standard motor (P/N 67127) and the high-torque motor (P/N 67126) are rated at 2.0 A/phase and are fully compatible with Sherline CNC systems, driver boxes, and motion controllers. The dual-shaft design allows you to add handwheels for manual control when needed. [accordion] [pane title="Features"]
• NEMA 23 frame size – fits Sherline CNC-ready mills, lathes, and rotary tables.
• Dual-shaft design – both ends of the shaft are usable; flats are ground on each end for secure attachment of handwheels and couplings.
• Standard step angle – 1.8° per step (200 steps/rev) for precise motion control.
• 2.0 A/phase – both motors are rated at 2.0 amps and work with existing Sherline CNC power supplies and driver electronics.
• 6-lead wiring – allows use in a variety of bipolar or unipolar configurations (see spec sheets for wiring diagrams).
• Designed for Sherline CNC – plug-and-play with Sherline driver boxes and motion controllers when used with the supplied connectors.

P/N 67127 – Standard Stepper Motor (with Plug)
The standard Sherline stepper motor (P/N 67127) comes pre-wired with six leads into a 5-pin DIN connector that plugs directly into Sherline’s CNC driver boxes and linear or rotary controllers. Simply plug each motor into the corresponding axis cable for a quick, clean setup. This motor is ideal for typical Sherline CNC applications where cutting loads are moderate, such as machining aluminum, brass, plastics, and light cuts in steel.
P/N 67130 – Stepper Motor (Without Plug)
P/N 67130 is the same basic motor as P/N 67127 but supplied with six raw wire leads and no connector. It is intended for non-Sherline controllers or custom installations where a different pinout or connector is required.
P/N 67126 – High-Torque Stepper Motor
Sherline’s high-torque stepper motor (P/N 67126) uses the same NEMA 23 frame size and 1/4" dual shaft as the standard motor, but delivers over 75% more holding torque. This added torque is especially useful on the Z-axis, where it can better handle the weight of the headstock and motor, and for heavier cuts or higher feed rates. Rated at 2 amps, the high-torque motor is fully compatible with all Sherline CNC machines, including complete CNC systems, the 4-axis driver box, CNC rotary tables, and Sherline linear and rotary controllers. No power supply upgrade is required. [/pane] [pane title="Specifications Comparison"]

[/pane] [pane title="Compatibility & Installation Notes"]
• Coupler requirement: Because of the increased torque, the high-torque motor (P/N 67126) must be used with the updated CNC coupling (P/N 671052). This coupling replaces the older 3-slot coupling (P/N 67105).
• Motor mounts: When used with a Sherline stepper motor mount (P/N 67101), be sure that the shaft entering the coupling has a flat aligned with the set screw. Tightening against the round shaft can damage the shaft and make removal difficult.
• Handwheel use: The dual-shaft design lets you mount a handwheel on the rear shaft for manual operation when the drivers are powered down. When the motors are energized, they hold position and cannot be moved easily by hand.
• Controller compatibility: P/N 67127 with the 5-pin DIN plug is designed to plug directly into Sherline’s 4-axis driver box, CNC systems, and linear and rotary controllers. P/N 67130 (no plug) is intended for non-Sherline or custom controllers.
Safety Note: The improper use of machine tools and accessories can result in serious injury. Always read and follow the instructions before installing or operating stepper motors, and always wear appropriate eye protection. [/pane] [pane title="Documents"]
