Abstract (en)
[origin: WO0226429A1] The invention relates to a heat-shrinkable chuck for clamping tools by means of shrink-fit. Said heat-shrinkable chuck comprises a chuck body (1), which can be fixed to the work spindle of a machine tool and inside of which a central seat (2) is provided for the shaft (3) of a tool to be clamped. The inventive heat-shrinkable chuck is characterized in that the central seat (2) is non-circular and has, along the periphery thereof, several interspaced clamping areas, which are situated on a common diameter and via which the shaft (3) is clamped. Damping areas (5) of a larger diameter are provided between said claming areas (4).
