CNCTOPBAOS K11 65mm Fourth Axis Rotary Table
The K11-65mm fourth-axis rotary table combines a compact rotary platform with a robust 63mm chuck suitable for 0.04-1.97 inch clamping ranges and a 4:1 reduction belt. The unit specifies a 54mm middle height and a total height of 85mm, enabling precise overt and indexing work on CNC routers and engraving machines. With a 0.3° step angle and a 20mm output shaft, it supports 3D cylindrical, bend, and circular processing, expanding the capabilities of standard 3-axis machines.
In addition to its rotary function, the included tailstock features a 54mm center height and a 30mm telescopic stroke, offering alignment stability for longer stock. This setup is well-suited for hobbyists upgrading their existing router to handle more complex parts and decorative carvings with repeatable accuracy.
Axiscreat CNC Router Machine 6060
The Axiscreat 6060 features a large 23.6 × 23.6 inch workspace and a 710W spindle. Its belt-driven X/Y axes with a linear rail Z axis balance rigidity and smooth motion, supported by an automatic tool setter and optical touch signal for quick, repeatable tool height calibration. The machine’s 6000–30000 RPM spindle range supports faster material removal and cleaner finishes on wood, acrylic, and other common CNC materials. This model emphasizes practicality for hobbyists needing bigger projects without sacrificing precision.
CNC Router Engraving Machine With 4th Axis
This model pairs a 4th-axis module with a 1:4 belt reduction and a chuck diameter range of 0.157–2.480 inches, enabling precise rotation for multi-axis engraving. It supports four-axis linkage for high-precision machining, achieving up to 0.020 inches accuracy when used with compatible systems. A large working area, up to 2.756 inches clamping diameter and 7.874 inches max length, supports a variety of material sizes and shapes. It’s a solid option for users seeking enhanced rotational control for detailed engravings and complex cuts.
Genmitsu CNC 3018-PRO Router Kit
The Genmitsu 3018-PRO is an upgraded GRBL-controlled kit aimed at beginners and intermediate users. It features an out-of-the-box ready assembly with an elevated base for stability and support for a 20,000 RPM spindle. The system runs Grbl, an open-source controller widely supported in the community, offering dependable performance for plastics, soft metals, and woods. It is well-suited for learning G-code control, testing simple designs, and starting small projects with accessible software and resources.
CNCTOPBAOS K12 100mm Fourth Axis Rotary Table
The K12 100mm rotary table from CNCTOPBAOS offers a 100mm 4th axis with a 65mm tailstock, and a 6:1 reduction ratio. It features an MT2 tailstock, a 65mm center height, and a 22mm through-hole shaft. The device uses a two-phase Nema23 hybrid stepper with a holding torque of about 1.8 Nm, delivering solid indexing and rotational precision for CNC engraving and milling. The included tailstock expands clamp stability for longer stock processing, enhancing reliability for cylindrical and arc-driven projects.
Buying Guide
Key purchase considerations to help choose among multi-axis CNC milling solutions:
- Rotary axis capacity: Determine if you need a 4th axis for engraving cylinders, curved surfaces, or complex assemblies. Check chuck size, reduction ratio, and tailstock features to ensure compatibility with your stock range.
- Work area and bed size: A larger X-Y work area supports bigger parts but requires more bench space. Consider the maximum machining length and clamping diameter for your typical projects.
- Spindle power and speed range: Higher wattage and broader RPM ranges yield faster material removal and cleaner finishes, especially on wood, plastic, and lightweight metals.
- Motion system quality: Belt-driven versus linear rails can affect precision and smoothness. Linear rails typically offer better stability for long cuts and high-precision tasks.
- Control software and ecosystem: GRBL-based kits are affordable and well-supported for hobbyists. Check for offline control, CAM compatibility, and available community resources.
- Upgrade path and compatibility: If you plan to add a fourth axis later, verify mounting interfaces, motor compatibility (NEMA sizes), and structural rigidity of the positioner and base.
- Durability and materials: All-metal constructions, robust tailstocks, and quality bearings reduce vibration and improve tool life in prolonged sessions.
- Support and documentation: Look for comprehensive manuals, setup guides, and responsive seller support to shorten learning curves and troubleshooting time.
Overall, your choice depends on whether you prioritize workspace and power (Axiscreat and WIZMAKER options), or high modularity and beginner accessibility (Genmitsu 3018-PRO). Rotary-axis capabilities extend traditional milling into multidimensional engraving and turning tasks, enabling more complex designs with the same machine footprint.
