Hello,
There is a small problem with aqua jet
cutting. It is difficult to explain for me as a Dutchman in English
but a water jet (even with abrasive additives) tends to act as a bullit. At the
entrance it cuts a small hole, at the other end there is a "big" gab.
Cutting thin materials is no problem but as soon as it gets thicker the jet
makes a connical hole. When you cut a round viewport you will end up with a
slightly connical one. This requires machining afterwards to meet
the neccessary tolerances.
Regards,
