Doris,
these machines are called "water jet cutting machines". They work
with a pressure up to 4000 bar. The water is not hot. If they cut
metal or stone a abrasive (sand) is added. They can cut basically
everything, like wood or one inch of stainless steel or marble or
titan. The company I am working for makes such machines. I don't know
any further details, because I am developing big lasers (really big
ones, like a truck!), which are a competitive technology. "My" laser
can cut 40 mm thick steel and weld 30 mm. That is slightly more, than
is needed for OM cameras..
