Note: All products listed are designed to expand a CNC setup with precise rotational capability, enabling varied machining tasks from engraving to 3D shaping. Each option’s suitability depends on your existing machine enclosure, spindle compatibility, and required precision.
CNCTOPBAOS K12-100mm 4th Axis
The CNCTOPBAOS K12-100mm 4th Axis combines a 100 mm rotary table with a four-jaw setup and MT2 tailstock. It offers a 6:1 reduction ratio for higher torque and stable rotation, suitable for CNC engraving and light milling. The unit supports a 22 mm inner through hole and a 30 mm output shaft, paired with a Nema23 stepper motor. Durable aluminum construction and precise gearing contribute to consistent repeatability for hobbyist to small-shop workflows. Consider mounting space, motor driver compatibility, and the required torque for your workpieces when evaluating fit.
CNCTOPBAOS K11-65mm 4th Axis
The K11-65mm system includes a 3-jaw chuck with a 63 mm capacity and an integrated 4:1 belt delay mode on the drive train. It supports a 20 mm gear output shaft, plus a 54 mm mid-height, enabling flexible fitting for compact CNC routers and milling machines. The tailstock offers 54 mm center height and a 30 mm telescopic stroke, with axial locking for stock stability. Prospective buyers should assess whether the three-jaw clamping range meets their part sizes and whether the belt-based gearing meets their precision needs.
Dremel 231 Portable Rotary Tool Shaper
The Dremel 231 turns a cordless or corded rotary tool into a compact bench-mounted shaper/router table. It accommodates sanding, edging, and trimming tasks for wood and soft materials. The unit is designed for easy tabletop mounting and straightforward setup, with simple knobs and a depth adjustment screw to control cut depth. Its main advantage is portability and quick conversion rather than heavy-duty production use. Assess compatibility with your existing Dremel or rotary tool, and confirm table dimensions suit your workspace constraints.
BLUEFOX TOOLS 4″ Rotary Table
The BLUEFOX TOOLS 4″ rotary table supports horizontal and vertical mounting, delivering 100 mm of effective workholding rotation. Its heavy-duty cast iron body provides stiffness and resilience during milling, drilling, and indexing. The hand wheel offers zero setting and fine graduations for precise angular positioning, with a 36:1 suppression ratio designed to reduce play. When selecting this model, consider the rigidity of your milling setup, the balance between precision and travel, and how often you need multi-axis orientation in a single fixture operation.
Buying Guide
Key considerations when choosing a CNC rotary table or fourth-axis accessory include compatibility, accuracy, and load capacity. Ensure the device can mount to your existing machine table or CNC router, and verify the drive system (gear, belt, or direct drive) matches your required precision and torque. Consider the tailstock design, center height, and whether a through-hole shaft is necessary for your workpieces. Material construction matters; cast iron offers rigidity, while aluminum bodies may save weight but can be less dampening. Evaluate the available range of motion, angular resolution (per step/degree), and whether the setup supports both horizontal and vertical orientations. Finally, assess vendor support, included accessories (e.g., tailstock, chuck, or adapters), and ease of integration with your control software and motor drivers. With these factors in mind, you can compare options that balance performance, footprint, and total cost of ownership across multiple manufacturers.
