- the further fastening elements 58 thereby secure the insertion tool 12 in the radial direction 30 and in the circumferential direction 34.
- the fastening elements 14 and the other fastening elements 14 Transmission elements 58 have a rectangular cross-section, whose corners are rounded.
- FIG. 9 shows a detail of an alternatively configured tool holder 210.
- the tool holder 210 has a receiving element arranged on the receiving side 214, which is provided for coupling with the insertion tool 12.
- the tool holder 210 has a total of four receiving elements arranged on the receiving side 214, which are provided for coupling with the insert tool 12.
- the fastening elements 214 correspond at least substantially to the fastening elements 14 already described.
- the tool holder 210 has a bearing unit 216, not shown, which is provided to mount the fastening elements 214 perpendicular to the axial direction 18 slidably.
- the bearing unit 216 comprises a linear sliding bearing.
- the bearing unit 216 is provided for movably supporting the fastening elements 214 in the radial direction 30.
- the tool holder 210 has a clamping element 224, not shown in more detail, which extends parallel to the axial direction 18.
- the tool holder 210 has a translation unit 222 that includes a translation contour.
- the translation unit 222 is provided for translating movement in the axial direction 18 into movement in a direction deviating from the axial direction 18 of the fastening elements 214.
- the translation unit 222 is provided for translating axial movement 18 into movement of the fasteners 214 in the radial direction 30.
- the fasteners 214 have a portion 264 which is formed pin-shaped.
- the pin-shaped region 264 extends in the axial direction 18 beyond the drive shaft 36 and projects beyond the drive shaft 36 in the axial direction 18.
- the fastening elements 214 each have a translation surface 228.
- the translation surfaces 228 are formed by bevels, which are tilted to the axial direction 18.
- the translation surfaces 228 partially form a translation unit 220 of the tool holder. 210.
- the translation unit 220 is intended to translate a completely deviating from an axial movement relative movement between the insert tool 12 and the fastener 214 in a clamping force F in the axial direction 18.
- the translation unit 220 is intended to translate the relative movement in the radial direction 30 between the insert tool 12 and the fastening element 214 into a clamping force F in the axial direction 18.
- the insert tool 12 In an assembled state of the insert tool 12 on the tool holder 210, the insert tool 12 is clamped by the movement of the fastening elements 214 in the radial direction 30 inwardly by the fastening elements 214 in the axial direction 18 on the tool holder 210 and held captive.
- the movement of the fastening elements 214 inward in the radial direction 30 causes a clamping force F in the axial direction 18 on the insert tool 12.
- the insert tool 12 is pressed toward the tool holder 210 and moves in the axial direction 18 along further, cone-shaped fastening elements 58.
- the further fastening elements 58 bear against the fastening elements 74 of the insert tool 12 formed by the fastening recesses 72 in the radial direction 30 and in the circumferential direction 34.
- the further fastening elements 58 thereby secure the insert tool 12 in the radial direction 30 and in the circumferential direction 34.
- the fastening elements 214 and the further fastening elements 58 have a rectangular cross-section, the corners of which are rounded.
- fastening elements 14, 1 14, 214 in the radial direction 30 are outwardly pivotable or circumferentially or tangentially displaceable and thereby cause a fastening force formed by a clamping force F in the axial direction 18 on the insert tool 12.
