A compact, high-precision 4″ (100 mm) diameter rotary table machined from solid steel bar stock and fitted with a 72-tooth, hand-cranked worm drive, providing 50 lbs horizontal and 30 lbs vertical continuous load capacity. With laser-engraved 5° markings on the table, 1/10° graduations on the handwheel and T-slots compatible with Sherline tooling, it’s built for milling radial patterns, indexing and rotating work on small mills. Proudly made in the USA, it offers instrument-quality finish, sealed worm drive, accessible oiler and optional vertical/trailing accessories for added flexibility.

Designed for CNC integration, this compact 4″ (100 mm) precision rotary table comes pre-mounted with a NEMA 23 stepper-motor interface in place of the traditional handwheel, enabling seamless use as a fourth axis in your milling setup. With the same rugged steel worm-gear construction and 72 : 1 ratio of the manual version, it maintains continuous load ratings of 50 lbs horizontal, 30 lbs vertical and 6 ft-lbs vertical torque. Backlash is held under 0.2° for consistent indexing. Proudly made in the USA, this table is ready to accept your CNC controls.

A fully integrated 4″ (100 mm) precision rotary table with a built-in NEMA 23 stepper motor and plug-in interface, ready to serve as the A-axis on your Sherline CNC milling setup. Designed for seamless G-code control and radial machining, it supports continuous loads of 50 lbs horizontally, 30 lbs vertically, and delivers approx. 6 ft-lbs of vertical torque. Backlash is held under 0.2° and it achieves roughly 28,800 steps per revolution (~0.006°/step) for high-accuracy indexing.

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.
