Document Type and Number:
Japanese Patent JP6530408
Kind Code:
B2
Abstract:
A chucking device for a tool includes a tool receiving element; a collet for clamping the tool, the collet being inserted in an opening in the tool receiving element; a clamping nut for axially displacing the collet in relation to the tool receiving element; and a pressure piece which is arranged between the clamping nut and the collet and is rotatably mounted in relation to the clamping nut, by means of which piece the collet can be axially displaced in relation to the tool receiving element by the clamping nut. To permit a tool shank to be securely clamped in and released from the collet, even under extremely high clamping forces, the pressure piece has coupling elements for a torsion-proof connection to corresponding mating elements of the tool receiving element.
