ABSTRACT:
A chuck for clamping an article has a receiving portion including a receiving bore having a longitudinal axis L, and a receiving bore inner surface. A clamping sleeve is accommodated in the receiving bore and is rotatable between a releasing position and a securing position. The clamping sleeve has a radially outwardly facing contoured clamping surface provided with one on more clamping segments, each clamping segment having a ramp between a trough and a crest, and a depression on the other side of the crest. Rotating the clamping sleeve within the receiving bore causes one or more rollers associated with each clamping segment to cooperate with the contoured clamping surface to effect the releasing and the securing of the article.
