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.

Included with the CNC Linear Controller:

  • Linear controller with integrated keypad

  • Power supply

  • #23 frame size stepper motor

  • Cables

  • Stepper motor mount

  • 24″ leadscrew

  • Dampened coupling

  • Preload nuts

  • Drill guide block

  • Complete installation and operating instructions

Power Supply Compatibility:
The included power supply operates on 110–240 VAC and automatically adjusts for international use (220–240V). Earlier versions of this product were supplied with a 110 VAC-only power supply.
