The 4th Axis Rotary Unit adds full rotational machining capability to your CNC system, allowing for cylindrical carving, indexing, rotary engraving, gear cutting, multi-sided machining, and more. Designed for stability and precision, this setup is powered by a NEMA 34 closed loop stepper motor, providing high torque, accurate positioning, and reliable performance under load.
This unit features a 100mm K12 4-jaw chuck and tailstock support, making it suitable for gripping a wide range of workpiece sizes. A 4:1 reduction ratio delivers smooth rotation and enhanced torque control, while the included HBS86H Hybrid Servo Driver ensures zero-lost-step performance with encoder feedback.
