| 20110156363 | TOOL HOLDING DEVICE - The invention relates to a tool holding device comprising a tool holding body for securing, in a fixed manner, a rotary tool comprising a shaft, provided with a clamping section and a receiving opening for the shaft of the tool, a coolant feeding device for pressurized fluid, at least one coolant guiding device for guiding the coolant into a clamped tool shaft. The coolant guiding device is designed as at least one flat groove on an inner side of the receiving opening, joining to the front side on a free end of the tool holding body and directly adjacent to the tool shaft in the surroundings of the tool holding device or a coolant storing chamber and/or collecting chamber is provided in the region of the free end of the tool holding body, to which the at least one coolant guiding device joins. The coolant storing chamber and/or collecting chamber is connected by means of an annular gap to the surroundings of the tool holder device. The coolant storing chamber and/or collecting chamber and the annular gap are defined at least partially by the work shaft. | 06-30-2011 |
| 20110248455 | SHRINK FIT CHUCK HAVING EXTENSION GROOVES - The invention relates to a tool holder comprising a tool receptacle in the form of a sleeve part, which comprises a tool receptacle opening comprising a mating surface which is concentric with the axis of rotation of the tool holder and on which the shaft of a tool inserted in accordance with the intended purpose thereof into the tool receptacle opening of the sleeve part can be fixed in a press fit, wherein the sleeve part comprises a number of circumferential recesses from the side of the mating surface, wherein the recesses divide the mating surface into several mating surface segments which are comparable to each other and which are substantially inherently rigid in the axial direction, wherein the radial depth of the recesses is selected such that the press fit releases substantially uniformly on all mating surface segments under the influence of heat applied over the outer circumference of the sleeve part. | 10-13-2011 |
