Indexing Chucks
Indexing chucks are workholding chuck systems for clamping and indexing the workpiece within the chuck setup. They are different from dividing heads and rotary tables, which are machine tool accessories for table-side indexing or rotary positioning.
Browse by Series
Multi-angle machining on intersecting-axis parts, valves and universal joints often uses spindle-side indexing chucks with rotary oil distributors, hydraulic systems and program-controlled indexing sequences.
TK Series Hydraulic Indexing Chuck
A TK series hydraulic indexing chuck for clamping and indexing workpieces in machining setups that require repeatable angular positioning.
Not sure whether you need spindle-side indexing or a table-side rotary unit?
Send your workpiece drawing, machine interface and indexing sequence requirements for engineering review.
Better fit / less suitable: quick guide
Spindle-side indexing reduces re-clamping; pure milling or table-referenced operations often rely on a rotary table instead.
Better suited to indexing chucks
- Turning is the main process and multiple angular positions are required
- Hydraulic pulse or program-controlled indexing is acceptable
- Workpiece geometry suits multi-station machining at the spindle
May need table-side indexing instead
- Heavy milling with the datum on the machine table (dividing heads / rotary tables)
- No stable hydraulic supply or limited control integration
Quick links by need
Indexing chuck selection points
Spindle-side indexing focuses on multiple angular faces in one setup; when milling angles are handled on the table, both datums should be defined in writing.

FAQ
What is an indexing chuck used for?
An indexing chuck is used to clamp a workpiece and rotate or index it to repeatable angular positions within the chuck system. It is suitable for multi-process machining, repeated angular positioning and batch workholding applications.
How is an indexing chuck different from a dividing head or rotary table?
An indexing chuck is part of the chuck and workholding system. Dividing heads and rotary tables are machine tool accessories used for table-side indexing or rotary positioning. They are selected for different installation positions and machining setups.
What information should I provide for selection?
Please provide workpiece size, material, clamping method, required indexing angle, machine interface, hydraulic or control requirements and the machining process.
