      Hello everybody,

      I am facing a problem while trying to find a workholding solution allowing to make the centering expander floating (in yellow on the photo) on the XY plane (+/- 1 mm in these two axes) and without play on the Z axis. I would also need the assembly to be hydraulically locked once the clamping points are in contact with the part.

      Here is what I design but I am not happy with it, mainly about sealling which can be complicated

      Do you guys have better ideas ?

      I am also working on a special 3-touch hydraulic centerer allowing +/- 1mm off center thank to hydraulic distribtion but it is complicate to find a simple and reliable solution to make each touch move independently and retratable with double acting piston
