Vevor Dividing Head BS-1 Dividing Head Set
The Vevor BS-1 dividing head offers a 6″ 3-jaw chuck and a headstock rated for up to 2500 RPM. The headstock tilts from horizontal to a vertical 90-degree position to accommodate varied workpiece orientations. With a 6-1/2″ swing, a 5″ center height, and laser-engraved scales, it supports 2, 3, 4, 6, 8, 12, and 24 divisions. The set includes three extra jaws for the 6″ chuck, enhancing clamping versatility. The construction, from HT200, provides rigidity with minimal backlash for accurate rotations, and a 1:40 reduction ratio supports precise indexing across multiple operations.
Key features include a solid frame that minimizes deflection during heavy cuts, clear measurement references, and an indexing circle for full 360 degrees. The laser-engraved scales help operators quickly set divisions and verify positioning. This is a robust option for shops needing a ready-to-use indexing solution with a larger chuck and comprehensive accessories.
VEVOR Rotary Table for Milling Machines 4”
This 4-inch milling rotary table from VEVOR is designed for precise positioning, rotation, and clamping of small workpieces in both wood and metal. It includes a 3-jaw chuck and external clamping range of 0.08″–0.98″ (2–25 mm) with a corresponding internal range of 0.98″–2.76″ (25–70 mm). A handwheel drives the rotation with scales on both the wheel and table to ensure accurate measurements. The table features a worm gear ratio of 1:36, meaning one full turn of the handle yields 10 degrees of table rotation—facilitating controlled indexing in tight tolerances and complex contour work.
Applications span small automotive parts, molds, and general machining where precise angular positioning is essential. The compact size makes it suitable for benchtop use or small milling machines that require reliable indexing without sacrificing space. Operators should consider the table’s load capacity and the compatibility of the included chuck with their tooling.
KAKA INDUSTRIAL Dividing Head 5 Inch
The KAKA INDUSTRIAL dividing head provides a 5″ 3-jaw chuck with MT2 tailstock for strong support of longer workpieces. It offers both direct indexing via 24 holes for standard divisions and indirect indexing using three plates (A, B, C) for extended divisibility from 2 to 50 and 51 to 380, excluding primes. The setup includes a 40:1 worm gear ratio to ensure precision in gear, face, and flute work. The tilting feature ranges from 10° below horizontal to 90° vertical, enabling angled machining conducive to complex geometries. A complete ready-to-use set minimizes the need for outfitting separately.
For shops focusing on gear cutting, multi-sided indexing, or custom-shaped components, this model provides versatility through both indexing methods and robust mechanical support. The MT2 tailstock improves stability for long operations. Consider the included accessories against your typical workflow to determine if this set covers your needs without additional purchases.
PRECISION QUALITY Tilting Milling Indexing Rotary Table
This 4″ tilting milling indexing rotary table combines precise tilting from 0 to 90 degrees with a 1:36 worm gear ratio, enabling incremental 10-degree movements per rotation of the handwheel. It includes a back plate and a 65 mm 3-jaw self-centering chuck that supports precise clamping for small to mid-sized parts. The combination of tilting capability and the included chuck broadens use cases, from pedestal components to curved surfaces and complex angle milling. The compact design fits small machine tools and helps achieve accurate datum references for indexing tasks.
Considerations include how often you tilt the table versus rotating it, the rigidity of the base, and the compatibility of the included chuck and back plate with your mounting pattern. This model is well-suited for general-purpose indexing with a focus on ease of adjustment and repeatable results.
4″ Rotary Table With Chuck (AD INTERNATIONAL)
This 4″ rotary table from AD INTERNATIONAL includes a 65 mm three-jaw chuck, back plate, and mounting hardware, providing a ready-to-use setup for precise rotation and indexing. The table’s construction emphasizes strength and stability for milling operations requiring consistent angular positioning. With a standard back plate that accommodates 3- and 4-slot configurations, it supports reliable workholding across a range of machining tasks. The system is appropriate for small to mid-sized parts where consistent indexing is critical for repeatable results.
When evaluating this option, consider whether you need additional grippers or a stronger clamping range for larger parts. The included chuck and back plate simplify purchasing, but ensure compatibility with your existing tooling and fixtures to maximize efficiency in your workflow.
Buying Guide: Key Purchase Considerations and Comparisons
- Indexing range and divisions: Look for direct indexing via multiple holes (e.g., 2, 3, 4, 6, 8, 12, 24) and indirect options using plates. A larger set of divisions enables more precise angular positioning for complex parts.
- Tilting vs. rotating capability: Tilting tables enable angled machining up to 90 degrees, which expands the range of possible operations, especially for chamfering, tapering, and contour work. If your projects require frequent angled setups, prioritize tilting models.
- Chuck size and compatibility: A larger chuck (e.g., 5″ or 6″) provides broader workholding for bigger parts, but may increase footprint and weight. Ensure the chuck is compatible with your workpiece dimensions and mounting plate.
- Back plate and mounting: A compatible back plate and mounting pattern (3 or 4 slots) ensures easy installation on your machine. Check whether the included back plate suits your table’s hole pattern.
- Headstock construction and rigidity: A robust HT200 or similar alloy frame minimizes backlash and deflection during rotation, improving repeatability for precision work.
- Gear ratios and handwheel feel: A worm gear ratio around 1:36 provides steady, predictable increments. Confirm that the handle turns yield the desired angular movement for your workflow (typically 10 degrees per full rotation).
- Direct vs. indirect indexing: Direct indexing is quick for standard divisions, while indirect indexing via plates offers a broader set of divisions but may require setup time. Evaluate your typical part geometry to choose accordingly.
- accessories and completeness: Sets that include additional jaws, tailstocks, and multiple dividing plates reduce the need for extra purchases. Confirm what comes with the product to ensure it meets your shop’s needs.
- Size and workspace fit: Ensure the table diameter and height fit your milling machine’s bed and clearances. Smaller benchtop units are ideal for compact shops, while larger fixtures suit bigger machines with broader work envelopes.
