Diaphragm
& Finger Chucks

Speedgrip Finger Chuck

Distortion free / reduced workholding solution
Merges diaphragm one piece flex plate concentricity and repeatability with collet-style individual fingers
Fingers grip 360 degrees with contour compensation
Uses: turning / lathes
Conforms to part shape to remove or reduce distortion for subsequent operations

Grip internally or externally by flexing action of a one piece basic plate with excellent hold and extreme accuracy
Diaphragm spread open or closed, ground for part size; return spring action creates grip force with excellent concentricity and repeatability
Designed with a flex point and controlled travel for excellent longevity
Grip force can be light or powerful, assisted by springs or drawbar/tube; released by return springs or drawbar/tube action
One piece construction for a specific part, or designed with interchangeable pads or inserts for various diameters
Machined with 3, 4, 6, 8, or 12 jaws for good chip escape with accuracy many times greater than a conventional 3 jaw chuck
Flexing action conforms somewhat to part shape to minimize chucking pressure and reduce part distortion

Uses: turning, drilling/milling, balancing, gear machining, grinding, inspection, and fixtures
Accuracy .0002-.005 T.I.R. typical for diaphragm applications
Excellent chip clearance
Adapt to most machines using available actuation or built-in actuation
Actuation available: manual, drawbar/tube, and built-in cylinder as required
