Finger chuck

High axial clamping force, even for asymmetrical workpieces

This chuck type is used in many variations whenever high axial clamping force is required or deformation sensitive workpieces have to be machined. The face clamping fingers can be arranged as required. Ideal for secure and precise clamping, for example of asymmetrical workpieces.

Problem	Properties	Workpieces
Clamping force adjustable over a wide range High roundness requirement Non-round clamping diameter Reduce machining operations Thin-walled components	Compensation clamping For high speed For non-round clamping ø For thin-walled parts Number of jaws > 3 Pull down	Cam Electric motor housing Flange Housing Milled part Ring Turbocharger

Technical features

Variable: Workpiece centring via holes, pins, mandrel, collet chuck or clamping jaws
For symmetrical and asymmetrical workpieces
Large stroke with planar pull
Close-to maintenance-free design possible
Can be realised either as a centric or compensating clamping device
Retractable clamping jaws possible

Typical applications

Face clamping for electric motor housings

Finger chuck with active support and damping system
Flat clamping of a housing

The clamping reference is in a defined angle to the axis of rotation.
