I was impressed by the advertising of the world's first desktop CNC Waterjet package, until I noticed the price. Not really in the bounds of the average ME and perhaps desktop referred to the use of a computer to develop the software to produce the waterjet cut items. But here's a link for anyone curious to see what's available. www.machineryhouse.com.au/W08720Brian |

Interesting. There's a YouTube video somewhere that a guy built one using a pressure washer.

Definitely exp0ensive and outside the pocket of most M.E.s What interested me was the difference between the desktop and the professional rigs. The desktop unit worked on 4600psi and the professional ones worked at 55,000psi....and No, that wasn't a mistake. 55,000psi! When I got the mild steel discs for the tyres for my stainless steel wheel castings, I got a local company to waterjet the centres out, to provide thin sections to turn the tyres from. As the width of the waterjet was only 1/16", the inner discs that they cut out, were able to be used to turn up the tyres for the tender, and pony truck, so big cost saving there on material, almost paid for the water jet cutting. Anopther advantage was that unlike any kind of cutting that generates a lot of heat, there was no heat with the waterjet so the other great advantage of waterjet cutting is there is no change in the crystaline structure of the steel.

If, like the professional cutters I use at work, you need to replace the nozzle at around 40 hours cutting that is an extra whole lot of dosh required! They are asking around $400+ for a nozzle replacement 'kit' whereas we pay around $130 for a nozzle.
We cut at 66,000 psi but some of the newer pumps can achieve nearer 90,000 psi!
