CNCTOPBAOS K11-65mm CNC 4th Axis
The K11-65mm 4th axis combines a compact design with a 63mm 3-jaw chuck and a 54mm tailstock height. Its 4:1 reduction ratio facilitates controlled rotation for engraving and milling tasks. The gear output shaft measures 20mm, balancing rigidity and precision for small to mid-size workpieces. This module is described as suitable for CNC routers, milling machines, and engraving machines, offering steady performance in varied setups.
CNCTOPBAOS K12-100mm CNC 4th Axis
With a 65 mm center height and a robust 100 mm chuck, the K12-100mm model supports MT2 tailstock interfaces and features a 6:1 reduction ratio. The dual-phase Nema23 hybrid stepper motor delivers 270 oz-in torque, supporting precise contouring and indexing for complex parts. Its aluminum base and hollow shaft enable lightweight, rigid operation suitable for professional engraving and milling applications.
CNCTOPBAOS 4th Axis With 3 Jaw Chuck
This rotating axis features a K02-63mm 4-jaw chuck with a 65mm tailstock. A 6:1 reduction ratio, 0.3° per step, and a compact form factor enable flexible positioning for cylindrical and curved surfaces. The unit’s sturdy aluminum alloy base supports multi-axis engagement for engraving and milling tasks across varied material types.
RATTMMOTOR 4th-Axis A-Axis
The RATTMMOTOR K12-65mm setup emphasizes a 54mm tailstock height and a 85mm total height with a 0.3° step angle. The 4:1 speed reduction and a reliable 63mm 4-jaw chuck deliver consistent clamping and repeatable indexing for precise CNC routing, engraving, and milling operations. The included wiring guidance helps ensure proper motor-to-driver connections for smooth operation.
OUYANG CNC Rotary Axis 4th Axis
OUYANG offers a fourth-axis rotary module designed for 4 to 60 mm diameter workpieces with a center height of 50 mm and an overall height of 77 mm. This module supports simple fixes to the router or CNC bed, enabling full rotary engraving from multiple angles. The kit provides two connection modes: direct motor connection or motherboard interface linking, allowing flexible installation with TTC450 and other machines.
Engraving Machine Rotary Axis 5th Axis Kit
This configuration supports a 5th axis with a 4:1 gear ratio and a 57 two-phase stepper motor capable of 1.2N·m torque. The 4th and 5th axis integration enables multi-angle engraving and broader toolpath control, expanding capabilities for hobbyists and professionals working on custom CNC router projects.
Buying Guide: Key Purchase Considerations
- Size and compatibility: Match the rotary table diameter, tailstock height, and Z-clearance with your machine’s bed, spindle, and work envelope. Consider MT taper compatibility (e.g., MT2, MT3) and the availability of a compatible chuck (3-jaw vs 4-jaw).
- Gear reduction and step angle: Higher reduction (e.g., 6:1) improves torque and fine control, essential for engraving and fine indexing. Step angles around 0.3° per step or 1.8° per step with a suitable driver yield precise positioning.
- Motor type and torque: Nema23 or similar hybrid stepper motors provide the torque needed for small to mid-size workpieces. Verify current, torque rating, and wiring (A+/A-, B+/B-) to ensure compatibility with your driver.
- Build quality and materials: Aluminum or aluminum alloy bases with robust castings offer stiffness and heat resistance. A stable tailstock and precise chuck jaws contribute to repeatable results.
- Mounting and interface options: Check mounting holes, T-nuts, and available connections to your router or milling machine. Some units offer direct motor connections or motherboard interfaces for flexible integration.
- Maintenance and accessories: Look for included accessories such as tailstocks, locking wrenches, and spare jaws. Consider the availability of replacement parts and service support from the vendor.
- Usage scenarios: For engraving and complex contouring, a 4th or 5th axis provides multi-axis indexing. For cylindrical parts or curved profiles, ensure the chuck size and center height accommodate the expected diameters.
When selecting a 5 axis CNC rotary table, balance mechanical rigidity, precision, and ease of integration with your existing CNC system. The options listed here emphasize reliable clamping, predictable indexing, and compatibility with common hobbyist and professional machines, helping you expand capabilities without sacrificing accuracy.
