Sherline has taken its P/N 3700 manual 4″ rotary table and applied a stepper motor mount with dampened coupling in place of the handwheel. The mount accepts a NEMA #23 frame size stepper motor for CNC control. This allows the table to be used as a 4th axis with CNC systems that have the capability to drive a rotary axis.
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.
The reverse rotary table is perfect for using on the tilting angle table (P/N 3750). The reverse mount allows access to the handwheel from the front of the machine (see photo below). If you used a standard rotary table in the previously described set-up the handwheel would be mounted facing the backside of the X-axis.

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.
