Sherline’s CNC driver box comes equipped with an A-axis output cable ready to drive a 4th rotary axis. The 8730 rotary table is all you need to turn your Sherline CNC mill into a 4-axis machine. Just plug the A-axis cable from the external 8760 driver box or the built-in driver box in your Sherline computer into the matching plug on the stepper motor. The EMC2 software is already set up to handle G-code for the A-axis, and numbers entered after the letter “A” in your code are interpreted in degrees.
The same end result can be obtained by ordering a 3700-CNC rotary table and a 67127 stepper motor and attaching the motor, but this single part number does the same thing, making it easier to order and saving you the trouble of installing the motor on the rotary table. This table is also available as P/N 8700, which includes a stepper motor and a self-contained CNC controller for use as a stand-alone CNC indexer.
NOTE: We are stating the following weight limits for our rotary tables for continual use.
- Horizontal orientation—50 lbs.
- Vertical orientation—30 lbs.
- Vertical rotational torque—6 foot/lbs. (meaning it can lift a 6 lb. weight when suspended 12″ away from the center of the rotary table)
The rotary tables can hold more weight when they are not under a continual load. Click here and here to see examples of different weights and uses for our rotary tables.

Use in laser marking systems
Sherline’s rotary table offers an accurate, stable platform for rotary laser marking applications. Its compact size makes it a good fit in small enclosures. See this YouTube link for a video of a Sherline CNC-ready rotary table in use in a laser marking application on a round part, illustrating the difference between trying to mark on a round part without rotating it vs. rotating it. The video is from Jimani Inc. Laser Marking Systems who use a high-speed motor to drive the table. A Sherline chuck holds the part. A second YouTube video from Jimani shows a typical round part marking operation from start to finish.
