Abstract
A clamping device for connecting machine spindles or basic holders with tool holders or tools for machining comprises two partable damping elements (38,40;138,140) which are radially displaceably mounted in a holder (24;124) anchored in the machine spindle (10,110) or the basic holder and in the parted position engage behind an encircling clamping shoulder inside the tool holder (12;112). The clamping elements (38,40;138,140) extend crosswise to the longitudinal direction of the tool holder (12;112) and, at their lateral outer ends, have clamping surfaces (48,50,52,54;148,150,152,154) disposed such that all four clamping surfaces of the two clamping elements (38,40;138,140) are each distributed over the periphery of the clamping shoulder at angular distances of approximately 90.degree..
