Abstract: A positioning device positions a tool holder (12, 14, 16, 18) on a tool turret (6) of a machine tool by positioning pins (10). The positioning pins are secured to the tool turret (6) and engage with receptacles (40) on the tool holder (6) when the tool holder (12, 14, 16, 18) is attached to the tool turret (6). At least one of the receptacles of the tool holder (6) is formed by a sleeve (40), with which the assignable positioning pin (10) engages in the mounted state while contacting the inner circumferential surface (58) of the sleeve (40). The inner circumferential surface (58) is part of an expanding part (56), which, when the pin (10) engages, expands elastically and flexibly away from the pin (10).

Abstract: A tool turret, in particular intended for use in a machine tool, is for an automated tool change process. In a work station (7) of the pivotable tool disk (5), a holder (9) intended for receiving a machining tool (15) can be attached to the tool disk (5) in a re-detachable manner by a clamping device (31) assigned to the work station (7). In an adjusting position of the tool disk (5) that differs from the working position (11), the respective clamping device (31) can be activated or deactivated, while leaving the holder (9) on the tool disk (5). In a changing position of the tool disk different from the working (11) and adjusting positions (57), the clamping device (31) unlocks the holder (9) in such a way that the holder can be removed from the tool disk (5) and replaced with another holder (9) to be used.

Abstract: A tool turret, in particular provided for the use for a machine tool, has a pivotable tool disk (10), which has on its outer circumference a plurality of receptacles (14) for holders (18) provided with working tools. The holders (18) are attached to the tool disk (10) in a changeable manner by a fixing device (20). Each holder (18) can be swiveled into a working position to permit the assigned working tool to be driven by a drive (22). For this purpose, the working tool can be coupled to an output shaft (16) of the respective holder (18) by a coupling device (26). The fixing device (20) can be actuated by the drive (22) when this drive (22) is uncoupled while stopping the working tool.

Abstract: Communication system and machine device. A communication system consisting of at least one data acquisition device (94) for acquiring sensor data of at least one machine device provided for cutting machining, preferably in real time, data collection device (102) for digitizing the collected data, and a data evaluation device (122) for the collected digitized data.

Abstract: A positioning device for positioning a tool holder (12, 14, 16, 18) on a tool turret (6) of a machine tool by means of positioning pins (10), which are secured to the tool turret (6) and which engage with receptacles (40) on the tool holder (6) when the tool holder (12, 14, 16, 18) is attached to the tool turret (6), is characterized in that at least one of the receptacles of the tool holder (6) is formed by a sleeve (40), with which the assignable positioning pin (10) engages in the mounted state while contacting the inner circumferential surface (58) of the sleeve (40), and in that the inner circumferential surface (58) is part of an expanding part (56), which, when the pin (10) engages, expands elastically and flexibly away from the pin (10).

Abstract: 1. A tool turret 2. A tool turret, in particular provided for the use for a machine tool, having a pivotable tool disk (10), which has on its outer circumference a plurality of receptacles (14) for holders (18) provided with working tools, wherein said holders (18) are attached to the tool disk (10) in a changeable manner by means of a fixing device (20) and, each swiveled into a working position, permit the assigned working tool to be driven by means of a drive (22), which for this purpose can be coupled to an output shaft (16) of the respective holder (18) by means of a coupling device (26), is characterized in that the fixing device (20) can be actuated by means of the drive (22) when this drive (22) is uncoupled while stopping the working tool.

Abstract: A tool turret, in particular intended for the use in a machine tool and for an automated tool change process, wherein in at least one work station (7) of the pivotable tool disk (5) a holder (9) intended for receiving a machining tool (15) can be attached to the tool disk (5) in a re-detachable manner by means of a clamping device (31) assigned to the individual workstation (7), wherein, in a setting position of the tool disk (5) that differs from the working position (11), the respective clamping device (31) can be activated or deactivated while leaving the holder (9) on the tool disk (5), and wherein, in a changing position of the tool disk different from the working (11) and adjusting position (57), the relevant clamping device (31) unlocks the holder (9) in such a way that it can be removed from the tool disk (5) and replaced by another holder (9) holder to be used.
