Buying Guide
Size, Capacity, And Workpiece Reach
Choose a size that fits your milling setup and typical workpieces. A 4″ (100 mm) table suits compact machines and small components, while a 6″ (150 mm) table provides more surface area for larger parts. For CNC-driven tasks or multi-feature parts, a larger table reduces fixture changes. Consider the clamp range and jaw options to ensure your typical stock can be securely held without collision with the table or spindle.
Horizontal, Vertical, And Tilting Capabilities
Models with horizontal and vertical mounting support versatile workflows. If you frequently need angled cuts or bevels, tilting tables (0–90°) expand capabilities and reduce secondary fixtures. For CNC work, a dedicated 4th-axis system with a motor (like a stepper) offers automated indexing, improving repeatability and throughput.
Clamping Options And Workholding
Clamping configuration matters for part geometry. Three-jaw chucks provide quick, centralized gripping for small parts, while four-slot or plate-based clamping plates offer flexible alignment and multiple point contact. Check external vs internal jaw ranges, and ensure compatibility with standard T-slots, clamps, and mounting hardware (M10 bolts, MT-2 adapters, etc.).
Accuracy, Gearing, And Readouts
Most manual rotary tables use a worm gear with a 1:36 ratio, yielding roughly 10° per complete handwheel turn. Look for precise scales on the wheel and table, with 0–360° indexing and clear graduations. For CNC use, assess angular accuracy, repeatability, and any play or backlash in the drive system. A stable base and good vibration damping are essential for consistent cuts and hole patterns.
Mounting, Compatibility, And Upgrades
Verify mounting compatibility with your milling machine (MT-2, T-slot beds, or specific clamp kits). Some models include tailstocks or modular accessories that can be added later (dividing heads, additional chucks, or indexing plates). If automation is planned, a 4th-axis unit with integrated motor and control options can streamline workflows and reduce setup time.
Practical Considerations And Durability
Cast iron is common for rigidity and vibration resistance, but weight and stiffness should match machine capabilities. Look for easily readable graduations, smooth rotation with minimal stickiness, and robust fasteners to prevent creeping under load. Finally, assess warranty, availability of replacement parts, and ease of maintenance to ensure long-term performance in a busy shop.
