摘要

Detachable highly accurate and rigid connection of a tool -, workpiece - or measuring tool - carrier (7) with a spindle head (1) of a machine tool spindle (3), comprising a on the spindle head (1) arranged first centring cone (6) as well as a flat first contact surface (22) of the spindle head (1), a on the carrier (7) arranged second centring cone (8) for the engagement on the first centring cone (6) and a flat second contact surface (10) to bear against the first contact surface (22), characterized in that one of the centring cone (6, 8) on a tubular connecting piece (15, 24) is formed and the axial length (16) of this centering cone (6, 8) 20% to 50% of the axial length of the tubular connecting piece (15, 24) is in such a way that this centring cone (6, 8) is designed elastically in the circumferential direction.
