    It seems a very dangerous idea, and robot is with far lower precision

    Normal 2D waterjet is enough to cut the granite slabs material.

    Is your robot waterproof? Dustproof? Strong enough to handle 20K psi+ ? Do you have an area that can support a huge mess? Waterjets are cool, but most people don't realize what kind of support equipment needed, the mess they generate, and the consumables. So, you would need a water tank to place the granite on, a supply pump to feed the booster pump, multiple filter systems, custom made high pressure lines and a garnet feed system (may not be required on granite) and a hardened nozzle to start with.

    Robot is kuka 180kg payload so it has enough power for waterjet.
    Repeatability is 0.1mm that is enough for me.
    Please see this video https://www.youtube.com/watch?v=qQ-76VCxs6I
    The cuts i want need 6 axis 3 axis are not enough..

    All the support equipment exists there is a marble processing factory.

    What equipment want for waterjet cutting granite 2cm & 3cm think with good speed ?
