Re: [CAD_CAM_EDM_DRO] Re: water jet

i don't know if 10,000 psi will cut much of anything unless its pretty soft.
we have a flowjet water jet machine where i work and the operating pressure
at the nozzle is 60,000 psi. with just water you can cut thru a piece of
rubber 1" thick at about 50 1"pm and for metals even with abrasives its
pretty slow.
