Abstract: A machine base for use in a machining system is provided. The machine base includes at least one work piece holder device receiving section having a work piece holder device interface, which includes an aligning device adapted for receiving the work piece holder device aligned on a z-axis. The machine base further includes at least one first machining unit receiving section provided with a first machining unit interface adapted for receiving a first machining unit including a first tool holder interface, and at least one second machining unit receiving section provided with a second machining unit interface adapted for receiving a second machining unit including a second tool holder interface. The first and second machining unit interfaces are arranged on opposing first and second sides of the work piece holder device interface and are movable at least along the x-axis or y-axis, respectively.

Abstract: A transfer machine: includes a frame, a table which is supported on the frame and can rotate with respect to the frame about a main vertical axis, and work holding assemblies mounted on the table. Each work holding assembly has at least one collet assembly for retaining a workpiece being machined. The collet assembly is able to rotate with respect to the table about a vertical workpiece rotation axis. The transfer machine includes at least one actuation motor in order to actuate rotationally the collet assembly and is provided with a driving shaft which can rotate about a respective driving axis. At least one transmission assembly can be activated selectively and is configured to transmit motion from the driving shaft to the collet assembly. At least one actuation motor is integral with the frame of the machine, with the respective driving shaft arranged horizontally.

Abstract: A holder system for mounting and aligning a machining device to a rotary transfer machine. The holder system includes a holder with a first part being mountable on a machine or being part of a machine as well as a second part which is releasably coupled to the first part in a defined first position. The second part is coupled to a third part, the third part coupled with the machining device. Positioning features are located between the second part and the third part to allow moving the third part relative to the second part in at least one spatial direction. Further, the holder system includes at least one alignment station that can releasably couple the second part of the holder to the alignment station in the first defined position and a measuring device configured to measure the position of the third part or of the machining device.

Abstract: The present application concerns a holder system for mounting and aligning a machining unit (30) to a machine (20), preferably to a rotary transfer machine. The holder system comprises a holder (1) with a first part (2) being mountable on a machine (20) or being part of a machine (20) as well as a second part (3) which is releasably coupled to said first part (2) in a defined first position. Said second part (3) is coupled to a third part (4), said third part including third coupling means (7) for coupling said third part (4) with a machining unit (30). Positioning means (5, 6) are located between said second part (3) and said third part (4) to allow moving said third part (4) relative to said second part (3) in at least one spatial direction.
