Shop RATTMMOTOR CNC rotary axis, 4th axis rotary axis K11-100 mm hollow shaft with 3-jaw chuck, dividing apparatus, a reduction ratio of 6:1 with 65 mm tailstock for CNC lathe, milling machine. Review: Great little addition - You can use it as a continuous drive, similar to a cnc lathe or as a indexing head, similar to a milling dividing head. I could not code for both Y axis and rotary axis together as I was restricted to using the Y axis as a Y axis or as the rotary axis. If you need to use the Y axis while rotary indexing, I suggest you use a DRO, maybe a vernier readout, to produce the distance moved, while you manually move the Y axis. Review: Rotory axis kit - Fantastic item, well made. Worth the price. ## Features - Package includes: 1 x 4th axle K11-100 mm kit (including stepper motor and 3 jaw chucks), 1 x 65 mm tailstock, accessories: set of claw protection and wrench. - Grundde Parameters -K11 100 mm three-jaw centring chuck: middle height: 65 mm; total height: 115 mm, angle: 0.3°/step, diameter of gear output shaft: 25 mm, with 57 stepper motor rotation ratio - 6:1, with 86 stepper motor rotation ratio - 4:1. - High quality – rust-proof dust cover, polishing and anode oxidation cover, rust protection coating.

Worth the price. ### ⭐⭐⭐⭐⭐ Review *by S***N on 3 April 2025* Ich hab die günstigste Variante genommen, da das Fräsen mit Rotationsachse für mich völliges Neuland ist. Der Reitstock ist halt die Sparvariante, das Backenfutter aber TOP. Ich habe am Anfang nicht kapiert das die Spannbacken eine Reihenfolge haben, ist mir aber dann schon klar geworden. Schrittmotor funktioniert super, musste ihn lediglich ein bisschen lockern, damit sich der Riemen nicht so toll spannt und er sich leichter dreht. Verwende einen X-Carve Controller, Achtung: Strom am Controller sprich Treiber richtig einstellen nicht vergessen. Alles im allen tolles Teil um den Preis, habe schon lange nach so einem Teil gesucht! ## Frequently Bought Together - RATTMMOTOR CNC rotary axis, 4th axis rotary axis K11-100 mm hollow shaft with 3-jaw chuck, dividing apparatus, a reduction ratio of 6:1 with 65 mm tailstock for CNC lathe, milling machine - STEPPERONLINE Digital Stepper Driver 1.0-4.2A 20-50VDC for Nema 17 and 23 Stepper Motor DM542T - Stepper Motor Driver Controller Integrated Board Forward/Backward Pulse Speed Angle Control Module PLC Serial Communication for NEMA 17 23 Motor --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/336887092-rattmmotor-cnc-rotary-axis-4th-axis-rotary-axis-k11-100](https://www.desertcart.tn/products/336887092-rattmmotor-cnc-rotary-axis-4th-axis-rotary-axis-k11-100) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-07-10*
