Who it fits
Good fit for
This setup suits hobbyists and small shop operators who need to add rotary capabilities to existing CNC routers or milling machines. The Nema23 motor provides the reliability needed for extended operation, while the 6:1 reduction ratio helps achieve finer indexing angles. Users who frequently machine parts with curves or angular features will benefit from the smooth positional control. The anodized aluminum construction ensures durability in environments where exposure to coolant or humidity is common, making it a practical choice for consistent, long-term use.
Who should skip it
You should look at another option if you require a larger chuck capacity or a different motor interface. The K11-100mm chuck accommodates internal diameters from 2 to 30mm and external diameters from 30 to 80mm. If your workpieces exceed these limits, this unit will not secure them properly. Additionally, this product is designed as a rotational axis add-on. It does not include a standalone base or power supply in the provided data. Users needing a complete, self-contained indexing solution without additional components should consider other systems.
Verdict: The VEVOR K11-100mm dividing head offers a spec-driven approach to adding 4th axis functionality to CNC equipment. Its robust motor and precise chuck make it a solid choice for angular machining tasks.
VEVOR K11 Specs Explained
6:1 reduction ratio
This gear ratio slows the motor speed to increase torque and indexing precision. It allows you to achieve finer angular divisions for complex machining tasks. The lower speed reduces vibration and noise, creating a smoother operation. This feature helps you position workpieces accurately without manual guesswork, making it suitable for detailed milling work that requires consistent, repeatable angles.
Nema23 2-phase stepper motor
This motor provides precise positional control with a compact 57x57x56 mm frame. It delivers high reliability and durability for extended use. The robust internal structure ensures consistent performance during continuous operation. This type of motor is common in CNC setups, offering better control over rotation than standard DC motors, which helps you maintain accuracy on intricate parts.
K11-100mm 3-jaw chuck
The chuck secures workpieces with uniform clamping force using three jaws. It includes internal and external jaws to handle different diameters. The through-hole diameter is 22 mm, allowing long stock to pass through. This versatility lets you clamp various shapes securely, ensuring your material stays stable during cutting. It is a standard size that fits many common milling accessories.
6061 aluminum alloy body
The exterior is made from 6061 aluminum with an anodized finish. This material offers excellent wear and corrosion resistance. It protects internal components from harsh workshop conditions and ensures longevity. The lightweight yet strong construction helps maintain stability during heavy use. This build quality is comparable to higher-end dividing heads, providing a durable foundation for your CNC router or milling machine.
Build Quality and Physical Layout
The listing describes a robust exterior crafted from 6061 aluminum alloy. This material choice suggests a balance of strength and light weight, which helps when mounting the unit on a CNC router or milling machine. The surface receives an anodized finish, according to the listing. This treatment provides wear and corrosion resistance, protecting internal components from harsh shop environments. You can expect better longevity in dusty or humid conditions compared to untreated metals.
Dimensions listed are 6.5 inches in width, 4.53 inches in height, and 8.27 inches in length. These measurements indicate a compact footprint that fits well on standard workbenches or machine tables. The K11-100mm 3-jaw chuck features a center height of 2.6 inches and an inner through-hole diameter of 0.9 inches. This layout allows you to pass longer tools or rods through the chuck center, enabling more flexible workpiece setups. The chuck securely holds items between 0.08 and 3.15 inches in diameter using interchangeable internal and external jaws.
The Nema23 stepper motor measures 2.2 inches on each side. Its compact size integrates neatly into the head’s housing without adding excessive bulk. The four-lead design supports precise positional control. This physical arrangement ensures the unit remains stable during extended operation. The solid construction and specific dimensions mean you can rely on consistent performance for intricate angular carving tasks.
Setup and Everyday Use Guide
Installing this dividing head requires aligning its mounting footprint with your CNC router or milling machine. The unit measures 8.27 inches in length, 6.5 inches in width, and 4.53 inches in height. These dimensions determine the space needed on your machine bed. You must ensure your worktable can accommodate this physical profile without obstruction. The listing notes two height variations, so verify your specific model matches your setup requirements before assembly.
Once mounted, the K11-100mm 3-jaw chuck becomes your primary interface for holding workpieces. The chuck features an inner through-hole diameter of 0.9 inches. This allows you to run long stock or tools through the center if your machining style requires it. The center height sits at 2.6 inches. This elevation affects how you position your material relative to the cutting tool. You will use the included internal and external jaws to secure items. Internal jaws handle diameters from 0.08 to 1.18 inches. External jaws grip sizes between 1.18 and 3.15 inches. Changing between these jaw types is designed to be straightforward, keeping your workflow efficient.
Daily operation relies on the Nema23 stepper motor for precise rotational control. The 6:1 reduction ratio ensures smooth indexing. This mechanical advantage lowers noise and vibration during complex angular cuts. You can process intricate designs with curves or angled features by adjusting the axis. The anodized 6061 aluminum body provides a stable platform for repeated use. The robust construction supports extended machining sessions without compromising positional accuracy. This setup allows you to tackle parts that standard 3-axis machines cannot handle alone.
Before You Buy This Dividing Head
Before adding the VEVOR K11-100mm to your shop, verify your CNC machine’s controller compatibility. This unit relies on a Nema23 stepper motor, so you need a driver that supports this specific motor type and can handle the 6:1 reduction ratio logic. Check your machine’s available axes to ensure it can integrate a fourth-axis rotational input without needing complex external hardware. You should also confirm your workspace can accommodate the 8.27-inch length and 6.5-inch width. The K11 chuck accepts small workpieces, so have appropriate collets or jaws ready for larger items. Regular maintenance involves keeping the aluminum body clean and the chuck jaws free of debris. This dividing head fits well alongside other precision benchtop tools. It complements standard drill presses and mills by adding angular capability. If you frequently machine complex parts, this spec-focused unit offers reliable indexing. Just ensure your existing setup matches its physical and electrical requirements before integrating it into your workflow.
Check before you buy
- Verify CNC controller supports 4th axis input
- Confirm driver matches Nema23 motor specs
