CNC Linear Controller with 24″ Leadscrew
This CNC power feed includes a stepper motor mount and a 24″ leadscrew for use with Sherline lathes that are not CNC-Ready. The stand-alone controller is programmable through its integrated keypad and directly controls the attached stepper motor, which can be mounted to drive the leadscrew of the lathe.
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 requiring a computer or master CNC controller. The controller can also be used in combination with existing CNC systems. Each unit is user-programmable with two independent programs of up to 40 steps each. For each step, you can set travel distance, direction, feed rate, and whether the sequence pauses or proceeds automatically.
The linear controller can also be daisy-chained with Sherline’s rotary controller (P/N 8700) to combine rotary and linear movements. This makes it easy to perform advanced tasks—such as gear cutting—without any CNC programming knowledge beyond the keypad interface.
Advantages of Using a Power Feed:
-
Provides a constant feed rate for a smoother, more consistent surface finish
-
Reduces the chance of errors caused by miscounting handwheel revolutions
-
Eliminates physical effort for long cuts or returning the saddle to the starting position
Programming is quick and straightforward. Stored programs can be executed repeatedly at the touch of a button with high precision.

Stepper Motor
Sherline stepper motors feature shafts at both ends, allowing for manual control via a handwheel, if desired. Flats are ground onto each shaft to accommodate set screws for the handwheel and coupling. For use with a Sherline motor mount, ensure that the shaft entering the coupling has a flat machined or ground onto it where the set screw secures it. Failure to do so may damage the shaft, making the coupling difficult to remove. For non-Sherline applications, the flat may not be necessary.
Powerful Dual-Shaft Motors
-
P/N 67127: This motor comes pre-wired with six leads in a connector that plugs directly into Sherline's linear or rotary controllers. Both our CNC system and driver box include four pre-wired cables with 5-pin plugs that match the P/N 67127 stepper motor. Simply plug each stepper motor into the corresponding axis cable for an easy setup.
-
P/N 67130: This motor features six raw wire leads, and does not include a connector, so that it can be used with non-Sherline controllers that have a different pin configuration.
Note: Due to the lack of standardization in the industry, wire colors can vary between suppliers. If using a connector not supplied by Sherline we recommend using a continuity checker to identify which wire connects to each pin on the DIN plug. Typically, the black and white (or tan) wires are connected to the center pins, but other colors may vary. See our specifications sheet for wiring diagram.


CNC Linear Controller – Z-Axis
This stand-alone controller is programmable from its keypad and controls the stepper motor's function to which it is attached.
An 8-pin mini-DIN cable can be used to connect multiple units in a "daisy chain." The units can signal each other to work in sequence, allowing multiple movements to be accomplished without using a computer or master CNC controller. They can also be used in conjunction with existing CNC controllers. The controller is user-programmable with two separate programs of up to 40 operations each. In each block, you can control distance, direction, speed, and whether the program pauses or proceeds to the next block.
The linear controller can also be "daisy-chained" with Sherline's rotary controller to achieve rotary and linear movement combinations. This makes it easy to set up for relatively sophisticated operations like cutting gears without having to know anything about CNC programming beyond what is entered from these simple keypads.
Using a power feed offers several advantages:- A constant feed rate gives a smoother, more consistent final finish
- The chance of errors due to miscounting handwheel revolutions is reduced
- No physical effort is needed for long cuts or returning the saddle to its starting position after a cut is complete
Programming is quick and simple, and programs are repeated at the touch of a button with high accuracy.

The controller power supply is 110-240VAC compatible. It automatically switches from 110V to 240V for countries with 220-240 volt electrical current. The original power supply that we offered with this product was 110 VAC only.


CNC 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.)
