Hi Magnus, hopefully I can assist some people here. Waterjet machines typically run at 50,000 psi of pressure. No math genius but 3800 feet per second. Think of a high powered rifle bullet. Water typically does not do the cutting alone, The cutting nozzle of the machine has a hole above it which sand/garnet is sucked in by vacuum. That sand is sped up to bullet speeds by the water. What thickness of steel can it cut? Its a matter of time, and how high the cutting head can rise. I have cut six inch mild steel and 5.5 inch stainless. Yet have cut product 10 inches tall but not thick. Water only cutting is also used my many industries. Water moving at the speed of a bullet can cut meat ( used often ), rubber, foam, gasket material. Cost of a 5 axis 5 x 10 waterjet machine is around $125,000 today. Prices vary. I have 5 years experience running multiple waterjet machines, 25 years running almost any cnc machine. I love waterjet machines because they can cut anything. I have cut everything. I work for a company that is a steel company. They make good money. Yet they want all business on their machines. We wont be cutting meat, but will cut Marble, Granite, porcelain, cement, inconel, aluminum, Mild Steel, Stainless, hardened steel, plexi, uhmw, lexan, teflon, wood, leather, glass, titanium, rubber, neoprene. Add insult to injury the parts dont need to be flat either. I beam, HSS, angle iron, all sorts of tubing. Many companies hire the lowest skilled people to work on waterjet machines. They get the lowest results too. Hire an operator/programmer to run your machines. I have been in machine shops for 25 years. I adore waterjet machines. I can blow anyones mind away, yet a waterjet machine is not always the fastest tool for the job. Normally anything under 1 inch thick a plasma cutter or laser cutter is 4 times faster. There is so much more to say. They are an amazing tool in almost any industry. Again not looking for an argument with laser operators or plasma operators. I run those machines too. Both are great tools and much faster than a waterjet if what you want to cut product the plasma table or laser cutter can cut. The waterjet machine can cut almost anything at any thickness.
Great video, Magnus! Love your explanation of the main components of the waterjet and how it works. Really glad to hear you've put it to good use and think it's an amazing machine.
mohammed yassin tanbour To Omax's machines you just need define the material, thickness and the cutting surface quality in the software to do the service. Normally we use the same pressure the cutting materials like carbon steel, stainless, titanium....the software will control the speed to different thickness. Basic if the material is thicker is necessary more time.
Magnus. Just finished watching your video. Very cool. Now I know the process. I have a thought about the heating of the water tank. Could you put a separate radiator to cool the water? Pipe it right outside like a heat pump AC unit only instead of Freon, its water. What do you think?
Ah, cool. I think we had a 500 hour (or could have been the 1000 hour) service last year ...I'm not sure if that's a rebuild or not (I had the OMAX dealer do it). It was a 4-hour job ...so maybe that's just a service and not a rebuild?
Here are some of the abrasive waterjets strengths: * Cut all sorts of shapes easily. Curves, corners, etc. * Cut nearly any material (Metal, stone, plastic, glass, etc. Even pre-hardened steel, and many traditionally difficult to cut materials.) * Practically no heat generated during cutting, so metallurgical properties are preserved. * Edge finish is excellent with typically little or no bur (sort of a sand blasted finish). * Very little loads on the material, so can cut and pierce brittle stuff * Reasonably easy to go from an idea/drawing to a complex cut. Typically the hard part is drawing the CAD file of what you want, but after that it's reasonably easy. * Small kerf, so little material removed / scrap pieces can be reused, parts can be nested, small details can be machined. * Quite precise (with some machines). I personally have done quite a bit of work below a thousandth of an inch, with 2 to 5 thousandths being more typical. A lot "depends" on the material being cut, and the machine doing the cutting, and the experience of the operator here. * Low side forces so can cut very thin webbing and the like. * Quick to setup and cut - typically just put your material down, fixture with a couple of clamps to minimize vibration, move the nozzle to position, and go. This makes it very good for onesy/twosy parts, and popular for those doing prototyping. * Cuts quite thick material. It gets very slow the thicker you go, but it can cut over 8" thick steel. (Practical in some cases, though less practical the thicker you go. I would say for Aluminum the practical limit is around 5 or 6", and for steel maybe 3 or 4 inches. However, it can cut steel up to maybe 10 inches, or aluminum up to 12 or so, which is practical every once in awhile. Super thick titanium cutting is quite practical due to the expensive material that can be saved by the narrow cut, even though it is slow. Titanium actually cuts faster than steel.) * No start hole required, as it can automatically pierce where it needs to. * Able to cut through non-uniform material, like wood with nails in it, or marble with veins, etc. * No heat affected zone, so it does not heat and change material properties. A traditional saw may be cheaper or faster and more appropriate for many jobs, like wood cutting, or just breaking something in half, or doing straight cuts. The waterjet is flexible enough to do that as well when needed. I would consider it a very complementary tool in a shop, that makes a lot of things easier/cheaper/faster, but not something to replace a saw for things that saws do well. Hope this helps.
Buck9MFG - TROLL HERO is right! The high pressure water is pumped through a jewel orifice in the nozzle, creating a vacuum which pulls the abrasive into the nozzle. The abrasive and water are mixed together in a mixing tube inside the nozzle. You can see diagrams and read more about how waterjets work on the OMAX web site: www.omax.com/learn/how-does-waterjet-work.
Omax is the worst, well decent for small shops that use it here and there but for big production, 22 hours a day cutting, negative. I used to be all Flow until company was sold to corporate big wigs and they've destroyed it, shut down all US manufacturing and sent it to korea and china. Now I have a Semyx Infinity 440, the 440 is for 4 meter x 4 meter which is what my gantries max cutting size is.
the title is HOW WATER-JET IS WORKING .. PLEASE Just explain Exactly how water jet works . How it cuts ... i got confused you jumping back and fort from the subject... like you are talking about a cool water or hot water... about water cooler .. that's noting to do with HOW WATER JET it Works.. Would you please add another video and JUST Explain about how water goes and pumps and mixes with sand and comes out and cuts... BASIC don't explain the X,Y,Z cnc machin.. Just the Waterjet ... please .////... thank you

Do you have multiple heads on a machine?
Thank you for this video. Now I understand how it works. Stay safe.
Thank you for taking the time to explain and tour through the facility. much appreciated.
What about the water from the tank because it goes back into the system,
how it cools, how it cleans from the sand, does it stay there,thanks..
Damn this cleared up one of the biggest questions I had. Water by itself can,t cut steel.
Great video, Magnus! Love your explanation of the main components of the waterjet and how it works. Really glad to hear you've put it to good use and think it's an amazing machine.
hahaa - thank you Omax! It is an amazing machine.
كيف نستطيع معرفة الضغط اللازم لنوع القطعة المراد قطعها
How can we know the pressure needed for the type of item to be cut?
mohammed yassin tanbour To Omax's machines you just need define the material, thickness and the cutting surface quality in the software to do the service.

Great video mate - as a CNC machinist that all made sense 😃👊🏽
Magnus a machine that size will set me back how much please ?
Great explanation Bro
thanks for sharing this interesting machine, chap
Hi. Very nice video. Thanks for sharing.
Well done, wish I had one and your gray matter
I love our Waterjet, we have the 1530 machine. Magnus, have you had to rebuild the pump yet?
Ah, cool. I think we had a 500 hour (or could have been the 1000 hour) service last year ...I'm not sure if that's a rebuild or not (I had the OMAX dealer do it). It was a 4-hour job ...so maybe that's just a service and not a rebuild?
getting to operate a water jet at work thanks for the video
"Eh'll zoom in for ya"
*gets once inch closer*
How’s Top Gear going?
Good stuff, Magnus.
what's the advantage of a water jet vs a saw? this seem slow and expensive vs a saw for cutting metal or a stone slab
Here are some of the abrasive waterjets strengths:
* Cut all sorts of shapes easily. Curves, corners, etc.
* Cut nearly any material (Metal, stone, plastic, glass, etc. Even pre-hardened steel, and many traditionally difficult to cut materials.)

xamomax thankyou for your reply
No heat generation is specially useful in knife and sword making so that proper heat treatment and hardening can be done .
So it is the pressure which makes it so sharp like a blade.. 2mm hole
So, impurities damage the head but the sand doesn't?
Azim Alif because the sand/garnet goes into the process after the orificie.
because the sand/garnet goes into the process after the orificie.
How is the expended garnet retrieved ?
i have a question
what is the approximate speed of water coming out of nozzle .... ?
I think around twice the speed of sound ...so likely around 1500mph.
Twice the speed of sound and the water comes out from a tiny hole (hair size hole).
Does the water jet channel uses sand and too ... ? It’s a 60,000 psi water jet ??
fantastic sir, thank you so much
do you use A-jet precision heads to cut with..
I'm not sure what that is?
You said the garnet can't go through the head, how does it get into the stream then?
Oh, I'm not sure... did I say that on the video?
Mmmm...I watched this video again and didn't hear you say anything about that...maybe in a previous one?
Yeah, I'm not sure. Maybe the nozzle was blocked at the time and we had problems.

Holy shit you have the same name I have!
what is the price for this machine?

Today's price it's $125,000
Thank U
veri veri fine sand
👍
AMAZING...
Thank U Dear
