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.
