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.
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.)
Compatibility with Tilting Angle Table (TAT) Limit Switches
