Waterjet Cutting Large Stainless Steel Gears

Fedtech uses 4-Axis waterjet cutting through stainless steel gears to produce an amazing and immaculate finished project. See the tight cutting tolerances and incredibly intricate cuts that needed to be made to process these custom gears with abrasive waterjet.

The pumps that are used are designed and built by Accustream, Inc. The pump is an intensifier pump that uses 3000 psi oil to generate 60000 psi Water pressure. With this pressure and a small amount of abrasive we are able to cut materials such as this.

Great question,

Abrasive waterjet cutting utilizes a high velocity coherent stream of water and abrasive that can be used to cut almost any materials . Water at 40,000 to 60,000 psi accelerates through a sapphire, ruby or diamond orifice. The stream passes through a mixing chamber where a vacuum, induced by the stream, sucks in abrasive. Momentum of the water stream accelerates abrasive as it passes through .the nozzle. The nozzle tip is usaully made up of a Carbide Matrix

abrasive waterjet is used with pressure at the nozzle of 60,000 psi. the abrasive used is a garnet abrasive at about 1 1/2 lb per minute.

I want one of these mounted on my front door

[WaterJetter08]

@freak2489 Can you imagine all the doors you could open?

[ishy321]

wouldnt it be easier to cast?

[WaterJetter08]

@ishy321 The quantity required was to low to cast.

How can it cut that step and not go all the way thru?

[WhereIsNumNum]

the worlds most fun super soaker

[wafflethug]

put that up someone's ass!

[some1otherthenthat]

@fastedos1969 I REALLY WANT TO KNOW THIS TOO, HOW TO CUT A STEP WITH THIS.... OR WAS IT ALSO MACHINED?

[driftability]

I have to pee.

chuck norris called he wants his water pistol back

[MovingUpp]

do the parts on these things wear out all the time? Get eaten up by the abrasive? Those tips, etc. Why aren't those orifices made of carbide or steel or whatever? why made of jewel-type material?

[Cursorkeys]

@WaterJetter08 Thanks for the info, I've found lots online about the 'jewel' orifice but didn't realise it was an actual jewel. All the sources say the exit velocity is designed to be barely sub-sonic, is this because a supersonic jet would cause damage to the material being cut?

[lilblitz]

would you beleive that was possible if you didnt see it happen

[faiz434]

@fastedos1969 Maybe by varying the pressure

[madmowerz]

ive always wondered what kind of pump they use to get the pressure that high
