Controller Power Supply
The included power supply is compatible with 110–240 VAC and automatically switches between voltages for use in countries with 220–240V power. (The original version of this power supply was 110 VAC only.)
Single-Axis Slide with Programmable CNC Contoller
Sherline’s single-axis controllers are designed to drive the stepper motor on any individual axis of a lathe or mill—no separate computer or driver is required. Each controller features an integrated computer chip within the keypad/control unit, allowing you to operate the motor directly from the keypad or enter simple programmed sequences—no G-code knowledge needed.
You can program parameters such as direction, travel distance, feed rate, and whether to pause between operations or proceed automatically to the next step. The controller can store up to 40 steps (each with four parameters) in either of two user-defined programs. Multiple controllers can be linked via cable to synchronize movements or can be connected to a larger CNC system using “sense” and “acknowledge” signals to coordinate actions within a CNC sequence.
Stepper Motor Mounting & Drive System
Each stepper motor mount includes dual ball bearings with a preload nut to eliminate endplay. A dampened coupling connects the motor’s 1/4" diameter shaft to the leadscrew. The dual-shaft stepper motor also allows for manual operation using the provided handwheel. The controller employs micro-stepping for precise, smooth movement.
Mounting Options
-
From the Bottom: Four 1/4-20 holes on 2" centers in the base for mounting from below.
-
From the Top: If bottom access is unavailable, use the included four angle clamps that fit into the perimeter groove of the base. Drill and tap the mounting surface for the included 10-32 socket head cap screws. Use all four clamps for maximum stability.

Power Supply
The included power supply operates on 115/120 VAC, 60 Hz (38 W). For regions with 100, 220, or 240 VAC and/or 50 Hz power, a step-down transformer is required. Alternatively, you may supply 24VDC, 1A (1000 mA) from a compatible local power source. Sherline does not offer a 220V power supply or transformer.
Weight Capacity
The slide has a weight capacity of approximately 10 lbs, depending on table length and load placement. For an 18" table, limit off-center loads (at the table end) to no more than 10 lbs. Heavier loads may be supported if centered near the base.
Duty Cycle & Maintenance
Under heavy, continuous use, you may observe wear on the anodized dovetail surfaces after one year (approx. 2080 hours). The slide remains fully functional, but regular lubrication with light oil is recommended to maximize lifespan.
IMPORTANT: Do not use WD-40 for lubrication. It will strip the anodized coating.
CNC Linear Controller with 15″ Leadscrew
This linear controller package includes a stepper motor mount and a 15" leadscrew for use on 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 is mounted to drive the lathe’s leadscrew. (A separate kit with a 24" leadscrew is available for 4400-series lathes—P/N 8880.)
An 8-pin mini-DIN cable allows multiple controllers to be connected in a “daisy-chain” configuration. The controllers can signal each other to operate in sequence, enabling complex multi-axis operations without the need for a computer or master CNC controller. The system can also be used in conjunction with existing CNC controllers. Each unit can store two separate programs, with up to 40 steps per program. For each step, you can define travel distance, direction, feed rate, and whether the sequence pauses or advances automatically.
The linear controller can also be daisy-chained with Sherline’s rotary controller (P/N 8700), allowing coordinated rotary and linear motion. This makes it easy to perform sophisticated operations—such as gear cutting—without any CNC programming knowledge beyond the keypad interface.
Advantages of Using a Power Feed:
-
Maintains a constant feed rate for smoother, more consistent surface finishes
-
Minimizes errors from miscounting handwheel revolutions
-
Eliminates physical effort during long cuts or when returning the saddle to the starting position
Programming is simple and intuitive. Stored programs can be run repeatedly at the push of a button with excellent repeatability and accuracy.

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

36V Closed-Loop Stepper Motor
The 36V stepper motor is a closed-loop motor with an integrated driver, housed in the same NEMA 23 frame as our standard stepper motor. It features built-in LED indicators that display both power and alarm status for easy monitoring.
⚠️ NOTE: The 36V closed-loop stepper motors are sold only as replacement parts for Sherline Accu-Pro machines. They are not available as upgrade components for pre-existing systems.
High-Torque Stepper Motor
Sherline’s high-torque stepper motor features the same NEMA 23 frame size as our standard stepper motor but delivers over 75% more torque - ideal for increased cutting feed rates and better performance on the Z-axis, where it can handle the added weight of the motor and headstock. Note that maximum rapid feed rate remains unchanged.
Important Compatibility Note: Due to the increased torque, these motors require an updated CNC coupler (P/N 671052, sold separately). If upgrading from systems using the discontinued coupler (P/N 67105), ensure you purchase the correct replacement.
Rated at 2 amps, these motors are fully compatible with all Sherline CNC machines, including complete CNC systems, our 4-axis driver box, CNC rotary tables and our linear and rotary motion controllers. No additional power supply upgrades are needed.
Dual-shaft design allows handwheel operation for manual control. Flats are precision-ground on both ends to secure handwheels and couplers via set screws. When used with Sherline motor mounts, the shaft end engaging the coupler must have a flat to prevent damage from the set screw. This may not be necessary in non-Sherline applications.
Each motor includes a six-lead cable with a 5-pin connector, pre-wired to interface seamlessly with Sherline's CNC equipment, making setup fast and easy - just plug in and go.
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.

18″ CNC-Ready Mill
The Sherline NexGen Benchtop Mill is the largest vertical milling machine we offer. As Sherline mills have become increasingly popular in industrial, laboratory, and educational settings, the need for a larger-capacity mill led to the development of the NexGen model. This benchtop mill features an expanded mill base, a longer crosslide table, and an extended column—providing greater work area and capability than our Deluxe 8-Direction Benchtop Mill (Series 2000/2100).
To fully support the extended travel of the column, we’ve increased the cross-section of the column base for added rigidity. To further improve stability during heavy cuts, the column arm no longer swings side to side. However, you still retain full flexibility with 90° rotation to the left and right, as well as in-and-out column movement—giving the NexGen mill a total of seven directions of adjustment, including X, Y, Z, and headstock rotation.
The NexGen mill is ideal for customers seeking a compact, high-precision mini mill for small parts. All Sherline milling machines are made in the USA and backed by exceptional customer support.
