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.
