ROTA DFF Rotary finger chucks
The rotary finger chuck is characterized by a high axial clamping force. The clamping fingers permit simple loading, even of automatic processes. The rotary finger chuck is particularly suitable for clamping workpieces which cannot be clamped radially.
The workpiece is clamped by retractable clamping fingers onto the flat side of the chuck. Pre-adjustment is done via 3 centric chuck jaws or via a springloaded pre-centering.
During the clamping operation the fingers move downwards in a translator way and simultaneously turn inwards. The clamping fingers dispose of an axial
length compensation and avoid misalignment of the workpiece.
