Waterjet Cutting Large Stainless Steel Gears

[wafflethug]

put that up someone's ass!

[driftability]

I have to pee.

[killertje847]

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?

[lilblitz]

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

[WaterJetter08]

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.

[madmowerz]

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

[WaterJetter08]

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

@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?

[vdubs4life1964]

what is the tip made out of?

[supereldinho]

Chuck Norris drinks that every morning...

[kimura2Loc]

y doesn't it cut the table and through the gear on the inside? did they used a milling machine for that part?

[DingleZilla]

I need one of these to cut a hole in the safe at my bank!

[totenkopf999]

You could slice bread with that unit.

[faostube]

60,000 PSI!?!?!?! holy sh2$@#$!! That's a dangerous machine. I hate to have a leak around that thing, reaching for a tool only to find out my arm just fell on the floor!

[SpartanAtom]

@faostube yea i use a double headed one, and its a badass machine u just gotta respect the dangers and read the manuals and have proper training ur all good. u can cut anything with this machine but its flippin messy when u use abrasive which is sand or something similar that combines with the water and cuts thicker material.

operating this machine is an excuse for the company ceo to watch over ur shoulder every now and then.

[WaterJetter08]

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.

[denismoloney27]

hi, is it just water or is there some kind of abresive material suspended. also do you know what the presure is at the nozzle

[freak2489]

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.

[ishy321]

@WaterJetter08 ahh i see, ye the patterns arent cheap :)

[davetileguy]

I could do this with my sawzall.

[WaterJetter08]

@davetileguy That must be one special sawzall. LOL

[davetileguy]

@WaterJetter08 I have special blades made of unobtainium!!

[tmcunlimited]

thanks .

[R75Sidecar]

How did it cut the pockets ? That's a milling job...

[WaterJetter08]

@R75Sidecar The pockets were machined with a milling op before the Waterjet cutting process.

[rollingstone70]

Cutting medium is not cheap... It works out to about $35 to $55 per hour of operation. And that gear would take a while to cut. Great piece of equipment but not cheap

[tmcunlimited]

do they sell a hand held version of this ?

[WaterJetter08]

@tmcunlimited There is a handheld version that is usd mostly for Cleaning. The force that is generated with an Abrasive cutting headed would be very dangerous to be operated in a handheld environment.

[glenn20081965]

Need one to do my patio.

[urbinaduet]

its 90,000 psi

[fastedos1969]

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

[Timespartan111]

@fastedos1969 loses pressure

[xXxMartin96xXx]

@fastedos1969

magic?

[faiz434]

@fastedos1969 Maybe by varying the pressure

[some1otherthenthat]

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

[mattyisagod]

is this cost effective?

[Serostern]

@mattyisagod Yes. It is an expensive machine, but the cutting medium and electric bill is cheap.

[sobija]

Yes....wather and sand mix and combination with high wather press. It's last tehnology of cuting.

[Nolansykinsley]

Garnet abrasive is usually what they use to get a realm high quality finish

[BinaryComa]

just out of curiosity what is the psi if the water need to cut stainless steel?

[coolaidkiller101]

@BinaryComa 10.000+ its not just water its water and sand sometimes

[KrazyKhris024]

@coolaidkiller101 Its gotta be more than that. at least 27,000

[kingmike40]

@BinaryComa Most of these machines produce 50,000 psi or greater.

[Aquahal93]

Would hate to be shot by one of these

[stalnierdzewna]

cool



[WhereIsNumNum]

the worlds most fun super soaker

[Evrythn1outof8infnty]

Works better in a vaccum

[tvobssesed]

This is what I do for a living !

[dtiydr]

Guess that took some time to do..

[baccus61]

They are machined on a milling machine after the job is cut on the waterjet.

[iamafractal]

how are the partial cuts in the center made? (where its thinner, but not cut all the way through)

[MKPitStop]

The watter will be shot at the cutting part for a correct amount of time to get the depth needed

[iamafractal]

ok so if the sides of the portion to be removed are cut, what about the bottom of that? does that part have to be gouged out?

[MKPitStop]

lol I am only geussing really, I would think that they would have to cut it all at that depth to get it out.

if you look at the end picture they have cuts right through so it might not be as bad as it sounds as there isnt that much to be left realy

[graffitiballz]

those are cast in
