A rotary table adds a precision, indexable rotational axis to a milling machine, allowing operators to cut arcs, bolt hole circles, gear teeth, and other rotationally symmetric features that are difficult or impossible to produce with linear axes alone. The accessories built around a rotary table, chucks, clamping kits, tailstocks, and dividing plates, are what determine how versatile and accurate that setup ultimately becomes. Buyohlic supplies rotary table accessories for machinists across the USA looking to expand their milling capability with accurate indexed and rotational work.
Why Rotary Table Accessories Matter
A rotary table alone can only hold a workpiece as effectively as the fixturing attached to it allows. Adding a compatible chuck turns the table into a rotating workholding center capable of gripping round stock directly, while a tailstock supports longer workpieces between centers, preventing flex or wobble during rotational milling operations.
Dividing plates, meanwhile, allow precise angular indexing for operations like gear cutting or bolt-hole patterns, where the table needs to stop at exact, repeatable angular positions rather than relying solely on the handwheel's graduated dial.
Common Rotary Table Accessories
- Self-centering chucks for rotating round stock accurately
- Tailstocks for supporting long workpieces between centers
- Dividing plates for precise angular indexing
- Clamping kits for securing irregular or non-round workpieces directly to the table
- Adapter plates for matching the rotary table to different mill spindle patterns
Common Applications
- Cutting arcs and curved profiles on a milling machine
- Machining bolt hole circles at precise angular spacing
- Gear cutting, when paired with involute gear cutters
- Indexed drilling and slotting operations
- Rotational fixturing for parts requiring multiple operations around a central axis
Choosing the Right Accessories
Start by confirming the mounting pattern and size compatibility between your rotary table and any chuck, tailstock, or clamping kit you are considering, since these components are not universally interchangeable across brands and table diameters. If gear cutting is part of your planned work, pairing your rotary table with a set of involute gear cutters and a dividing plate suited to the tooth counts you need will round out a capable indexing setup.
Compatibility Note
Rotary tables are commonly sold in a range of diameters, most often between 3 and 8 inches for hobbyist and small shop use, with larger diameters offering greater surface area and torque capacity for heavier fixturing. Always check both the table diameter and the specific mounting bolt pattern before ordering a chuck, tailstock, or clamping kit, since accessories sized for one table diameter will not necessarily bolt directly onto another without an adapter plate.
