What is a fixed hydraulic collet chuck used for?

A fixed (stationary) hydraulic collet chuck mounts on a machine table, tombstone, or fixture —not on a rotating spindle. It is used on machining centers, milling machines, drill presses, and tapping machines to clamp bar stock, shafts, and round parts for drilling, milling, tapping, and secondary operations.

How is this different from a lathe hydraulic power chuck?

Lathe power chucks rotate with the spindle for turning. A fixed hydraulic collet chuck stays stationary and is fed by shop hydraulic pressure to open/close the collet. It is the right choice when the tool rotates (mill, drill) but the workpiece remains fixed or is indexed on a fixture.

Do you offer pneumatic versions and custom sizes?

Yes. KORRETTO supplies both hydraulic and pneumatic fixed collet chucks, custom clamping bores, and mounting interfaces for your VMC table or sub-plate. Send your workpiece diameter range and machine model for a recommendation.

Fixed Hydraulic Collet Chuck

KORRETTO fixed hydraulic collet chuck (stationary type) is built for machining centers, milling machines, drill presses, and tapping machines —not for rotating spindles. It uses an integrated hydraulic cylinder to clamp bar stock and round workpieces with a hydraulic collet chuck mechanism. Keywords buyers search: stationary hydraulic chuck, milling collet chuck, machining center workholding, collet chuck for milling machine, VMC workholding. Optional rubber-flex collet configuration offers long stroke and high concentricity for finished surfaces.

Designed for drill presses, tapping machines, milling machines, and vertical machining centers (VMC) —ideal for clamping bar stock and cylindrical parts in stationary fixtures.

Integrated hydraulic cylinder in a compact body; easy to mount on machine tables, tombstones, or sub-plates for repeatable production.

Collet system can use rubber-flex collet technology where long stroke and high clamping accuracy are required.

For CNC lathe spindle workholding with flexible rubber collets, quick collet change, and bar-feed–ready through-bores, see Rubber Collet Chuck · Clamping Head for Lathe & Machining Center.
