Hydraulic Auto Indexing Chuck
A hydraulic auto indexing chuck for automatic indexing and clamping within the chuck system. Suitable for repeated angular positioning, multi-process machining and batch workholding setups.
Indexing chucks for CNC lathes, spindle-side multi-angle machining and repeatable angular positioning.
Indexing Chucks
KORRETTO manufactures indexing chucks for CNC lathes, including hydraulic automatic indexing systems and TK series models. Use this collection page to compare spindle-side indexing options for multi-angle machining, repeatable angular positioning and batch production. These products are different from dividing heads and rotary tables used for table-side indexing.

TK Series Hydraulic Indexing Chuck
A TK series hydraulic indexing chuck for clamping and indexing workpieces in machining setups that require repeatable angular positioning.

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

Hydraulic 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 for a CNC lathe clamps the workpiece at the spindle and indexes it to repeatable angular positions for multi-angle machining, reduced re-clamping and batch production.
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.
