Message: <blockquote data-quote="Shadowrider" data-source="post: 4245300" data-attributes="member: 3099">Ours did. But we were cutting stuff not normally cut on a waterjet.We bought the machine from Lockheed Martin in Ft. Worth who designed and built it. It had a 5 axis robot control instead of an actual machine tool control with the waterjet cutting software that makes waterjet machines so expensive, That's probably why they sold it before ever even using it. But it still worked for our purpose which was nesting parts in aluminum plate. Saved many, many thousands in material cost.  It had a huge table and a 60HP motor that drove the main water pump. The water stream moved at around Mach 3. It used either a ruby or sapphire orifice, I don't recall which, it's been too long. We used garnet for abrasive because it was cheaper and cutting aluminum plate up to 4.25" thick, you can imagine how much of it we went through. It was injected into the water stream after leaving the orifice. We could cut without it, but it was already a pretty slow affair on stuff that thick, without it was a lot slower. On a lark, the owner has us try a titanium forging that was 8.5" thick. It did it. Only went .100" per minute, but it did cut through it. Sparked a lot...</blockquote>
