Abstract

The invention relates to a clamping element (1) and to a clamping body (104, 204) for a clamping device (100, 200) for clamping a workpiece (101) or a tool, to such a clamping device (100, 200), and to a method for clamping a workpiece or tool. The clamping element (1) has at least one clamping face (3) for the workpiece (101) or tool and at least one supporting face (2), facing away from the clamping face (3), for supporting on a supporting face (106) of a clamping body (104) of the clamping device (100). The clamping face (3) and the supporting face (2) are formed by two or more respective clamping-face and supporting-face segments (4,5) that are spaced apart from one another in the circumferential direction (U). The clamping-face segments (4) and the supporting-face segments (5) are spaced apart from one another in the radial direction (R). Each clamping-face segment (4) is connected via two connecting elements (6, 7) to two supporting-face segments (5) that are adjacent in the circumferential direction (U). At least one clamping-face segment (4) and at least one supporting-face segment (5) connected thereto are arranged in a manner offset with respect to one another in the circumferential direction (U) by an offset angle (β), with the result that an acting direction of a radial supporting-face pressing force (FA) acting on the supporting-face segment (5) in the radial direction (R) and an acting direction of a clamping-face pressing force (FS) acting on the clamping-face segment (4) of the clamping element (1) both in the radial direction (R) and in the circumferential direction (U) are offset in the circumferential direction (U) by a pressing-force angle (γ) and/or an acting direction of the clamping-face pressing force (FS) acting both in the radial direction (R) and in the circumferential direction (U) and an acting direction of a clamping force (FR) acting on the clamping-face segment (4) are offset in the circumferential direction (U) by a clamping-force angle (δ).
