CNC rotary axis 4th axis attachment adds controlled rotation for engraving and milling complex curves, flats, and indexed features on your CNC router. This dividing head uses a K11-100mm 3-jaw chuck and MT2 tailstock with a 65 mm (2.6") center height to hold work securely while the 6:1 gear reduction supports smoother motion, finer indexing, and more stable cutting.

Set up a reliable A-axis indexing head to expand what your CNC can produce—nameplates, cylinders, multi-sided parts, and detailed engravings that demand consistent rotation. The through-hole design and strong clamping help keep round stock centered, while the geared drive and Nema23 stepper motor support predictable movement for toolpaths that need tight control. Ideal for makers and small shops upgrading to rotary machining without rebuilding their workflow. Grab yours today and start cutting more angles with fewer resets.
