- SchGo Engineered products is premier waterjet cutting service in Southern California. We provide reliable, top quality and highest precision waterjet cutting in the industry.
Surface shown on 0:13-0:15 is as cut surface, no secondary smoothing process. Surface look like sandblasted. No heat affected zone. We combined the best garnet, pressure and optimal path. It produced clean and precise cut, both halves completely separated without difficulty as in 2:03.
What I find most impressive is how it maintains a precision cut through such thick material! Like a scroll saw or band saw would.
Waterjet always leaves a slight taper on the edges of the cut material. As the thickness of the material increases, so does the angle of the taper.
I kinda figured it would.
Yes, always have slight taper. however, the taper angle should maintain with only slight variation. The thickness differences between top and bottom will increase as cut thickness increase. This taper angle can be minimize by user taper control cutting head.
The cut is very precise close to the nozzle. Waterjet is flexible cutting tool. As it get further away from the nozzle it tend to lag behind. It tends to cut more precise with harder material than soft. Precision are controlled by adjusting cutting pressure, speed of cut, and the cutting media (garnet).
If you increase pressure can you reduce taper? I'm thinking so...
Thanks for taking the time to answer questions in the comments. Very informative and interesting.
Im supposed to be doing my engineering homework but man is this cool!
I am degree MS Mechanical Engineer. Which engineering major and what grade. Thank you for your interest. We help some local high school and college with free cutting service for their project..
Water-jet will only become more important to the metal fabrication & welding profession.
Thanks for the great video.

Thats very impressive. Going to have to research your nozzle material. Sounds like something the company I work for should be making.
Tony Thomas carbide? It wears off in about 50-100 hours
That's impressive! 4" 316L SS is the largest I've cut so far. I can't imagine the pierce time...let alone the pitch as it gets an inch or two in. Appreciate the video and hope to see more.
The cut does not required piercing through the thickness. All cuts started from edge of material. The challenge is to avoid the jet skip as it exiting the material.
I generally back down the feed rate. If you exit too quickly, the cut isn't always completed,due to jet kerf, and blow back of the stream.
I'm no expert, so I appreciate any and all knowledge you share.
It's all about try and error. For this i have to slow down to about 1/10 of the cutting speed before exiting and time it right. The result is smooth cutting all the to the bottom. The three pieces just fall apart at the end.
Email me. Lets share our experience.
I've heard of water jets cutting 16 inch SS. insane!
very cool stuff , thanks for posting .
If you ever had time , it would be interesting to have a look at the workings of the water jet , pump/pump motor specs , controls , etc .
cheers .
Okay China, nice try. lol
WOW! 2000 mph that is like the SR-71 BLACKBIRD!!!!
i can run that fast, and if i cant my pee stream is pretty similar
Bloody alien technology!! Amazing
Nice, What was the feed rate,? I can't think of a faster way to cut that, Band saw would be ridiculous, they only other way to make that would be 2 or more pieces, welded together, or cast, which is, not as strong, but we don't know what it is or what it's for,.
0.16 inch per minute. In some application, part need to be made out from solid billet material. By cutting them this way, we can save material cost. 2 pieces out of one block. Otherwise, is one piece per block and a lot of machining time required to remove big chunk of material. This is a very difficult material to machine by milling
UHP waterjet cutting, cool
That's incredible! Thanks!
0:04 that strata and the scree slopes leading would to a wide valley is a perfect example of the phases of The Flood 4,350 years ago.
Waterfall is at Mendenhall Glacier in Juneau, Alaska. Rocky area is Grand Canyon shot from river toward south rim. a 4 day backpacking along the Colorado river.
SchGo Engineered Products, Inc. Hi, thanks, I wasn't sure where the waterfall is but I thought the other was typical Grand Canyon Flood terrain.
I doubt if any UK company could waterjet 8inch stainless as we are still in Flintstones Era in engineering and practically everything in the country is imported.
@@rosewhite--- That is a shame, the natives on that island(s) were always typically super creative, inventive, and uncommonly clever. You should definitely be into the high tech manufacturing. Your government fails you (and mine as well).
@@Barefoot433 Our Govt has been failing us for about 50 years or more.
Investing in production is seen as evil and all our industry has been sold off to foreigners or shut down.
Plus unlimited illegals pour into the country !
UK and USA are in a mess.
Is it precise enough to cut a granite slab so as to place a induction cook top flush with the same plane as the granite. With perhaps a super minor clearance around the border to mitigate grime accumulation. Looking for a kitchen where the cooktop would be indistinguishable from the granite counter top, i.e. could pull a squeegy across the top and clean and dry it.
does it cut evenly? the water looks like it has a wider spread the further it gets from the nozzle which seems like common sense. Surely this would have some effect on an 8" cut.
It does spread out a little bit, but the head can tilt to compensate.
Yes, we use tilt-A-Jet from Omax to compensate the taper.
I m curious why does nozzle does not wearing out itself , what protects it ? this water send mixture goes in the same nozzle which cuts the metal
Levan Gejadze, they use tungsten carbide nozzles.
The nozzle will wear out too but at a rate much slower than the metal. Nozzle is made of carbide material.
Water/garnet mixture is guided by a diamond orifice to go through the center of the nozzle. This minimize the contact between mixture and wall.
During cutting the mixture is constantly pushed into the material. It erodes the material as it goes.
opening show show impressive amount of sediment layers laid down during The Flood 4,350 years ago.
The canyons were carved by the receding waters collapsing the still soft sediments.
lol
Pure water 💧 아니겠죠.??
What happens if you would start cutting in the middle of the piece? I would guess the cut wouldn't be clean cause the material couldn't escape properly. Opinions?
It will take approximate 10 minutes to pierce through the part. the pierce length will to be about 1" long. It is a wiggle pierce where the jet will move back and forth to allow the water and sand to bounce back out. Most of the time sand collide to each other inside the pierce hole. Using hard rock garnet instead of alluvial garnet. Higher HP, pressure, larger garnet flow will speed up the piercing and cutting.
can this be used in steel sections for construction? How would they put it on the platform because steel sections can be pretty long
This is very impressive. I would imagine that the grains would clog up in the slit, preventing new cutting sand to efficiently cut through the work piece.
What is the typical flow, speed and cross section of the water beam when cutting at such insane pressures?
Water flow through about 1-2 gallons per minute. Cutting kerf/width is about 0.042". Water shooting out the nozzle at 1700-2000 mph. Since there are no piercing in the middle of part, water and sand are push from top through the 8 inch thick. cutting jet slack is about 1/2" from top to bottom.
It would seem that at that pressure and going through steel that thick would build up so much friction and heat that the jet of water would turn into steam before going all the way through. I'm impressed!
How do you keep the water from turning into steam?
Jeff......
No steam, but the holding tank can get very warm after several hours of run time.
it all happen in micro seconds as each drop of water travel through the steel surface so fast. Yes, the tank water will get warm up to about 100-120F in hot summer day.
Is it just the sheer pressure of the jet of water that cuts through?
No it is a mixture of water and sand (garnet) that doing the cutting. High pressure is use to push it through.
if 8 inch steel cant stop it from penetrating....whats actually stopping it from making a hole down through the tank...i mean why is it not hitting the floor...?....
water
Garapati Raja I reckon the water pool disperses the energy of the water significantly
im guessing cuz water cant cut water
About 8 or 9 years ago, a company I worked for ran a test for a customer to prove we could cut through a reactor wall, we retrofitted the water jet table with a 100 hp system, we placed a 12" block of steel on the table, the jet cut thru it easily, buy the jet also continued thru the 2" grate, 12" of water, the bottom of the table, and into the concrete floor. So, we had to find a material to stop the beam, we built a tungsten carbide catchers mitt, it worked vary good, we were able to cut a reactor with 17" thick walls, into pieces to decommission it.
+Richard Archuleta what about 36" of water?
wow amazing !! i have question (silly) question, does the water heat up ??
yes, after cutting 12 hour continuously, water can heat up to about 120 degree F. It is abrasive cutting. Heat is generated when garnet grind the metal away. It is like sand paper chipping metal at much higher speed. Water as media carrier.
SchGo Engineered Products, Inc. thank you
What is velocity of water??? Any physicist??? I guess it reaches km/s
KISMO KIBO usually it goes up to Mach 3 or more so roughly 1km/s+
Make a portable version and what's to stop you from getting into a bank vault door?
portable waterjet, bank vault door, money, jail..... Chicken and egg which come first?
SchGo Engineered Products, Inc. Priceless reply, good one...
*Is their a thing that waterjet cannot slice or cut?*
Do you made a machine with the small size, like Wazer? I just need a machine within 100x100 cm working space
Fascinating. Anyone know what kinda power (KW) this thing uses to generate 60 kPSI of pressure?
all runs on a 9v battery.
50 hp electric motor, 600 volt 3 phase connection, the motor and pump combined produce about 94000 psi at the pump and is controlled at source to do usually 60/65000 psi, super good ,precise and fast at lower material thickness, to cut this stainless takes quite a while in the range of more 1 hour, your water and pump source must be a minimum of 15 gallons a minute to perform these jobs, even these machines have their limits as anything else, for hardened steels like boron, boron with carbon5 a plasma cutter performs better faster and more cost effective than a water jet, lower cost overall, water jets you must always have a clean water source and the consumables are a much higher cost, a ton of crushed garnet abrasive is loads of money versus copper or brass consumables used on a plasma, both machines have their drawbacks and limits, the cool factor has to go to the water jet though, the plasma is still very cool as it cuts under, they normally use electricity, oxygen, compressed air, the electric source is the same allot of theme 600 volt 3 phase, i regularly cut heat treated boron that is very hard that you can't drill or cut easily but with using a plasma cutter, boron 1 3/8" thick cuts clean and quickly performing 4 passes over 8 foot lengths in 18 minutes which is almost17 feet/minute in the program and fully automated each part weighs 350 lbs when the cuts are done its almost 35% lighter
Looks like a Tiltajet with a .042 thou mixing tube!! Quality 4 or 5 or a good 3!! Good job though 👏👍!!
How does it not destroy the nozzle?
i honestly thought it would have a cutting depth of about an inch,
Very impressive . H2 Whoooah
It is not only water that is used, a fine grit is also in the waterjet.
Garnet
What inches per min and psi is this?
Now my PC has water all over it!
really impress me... aim it at a lion or elk let see if they can maintain a steady drink without it going through their heads
is it possible to do landscape pictures with a water jet? like maybe monument valley or the New York skyline
It is possible with good control of cutting pressure, water and garnet flow rate
If only I could afford one.
What generates the pressure? And does it have to use deionized water?
Atomkey Sinclair they work with hydraulic multipliers
Thank you for that answer...
Pressure was generated through 3 high pressure pistons in parallel. They were driven by 50 HP motor.
Water is fetch directly from city water supply. Some company use deionized water to minimize build in the piping.
Whats the cut rate on something that thick? mm per hour?
soon all military forces will use water guns instead. super soaker timeeee!
Lord Rixuel yeah they'll just run up close enough to eachother that they can hold a water jet 2 inches away from another person
That means the enemy must be centimeters close which is impossible
These are the people that they allow to vote. You should be forced to pass a basic apprehension test
This is incredible!
it's mixture of high pressure water and garnet that do the cutting. The mixture shoot out through a 0.030" diameter nozzle.
What is the recoil force generated by that jet of water? It must be pretty significant.
No idea. The nozzle is mounted onto a frame that secured onto an X-Y gantry. If you have a way to measure, i might try it.
Well, that was my lazy version of the question. What is the discharge rate? I could do a force equation and figure it out if I knew the discharge rate, I am just lazy and was hoping for the easy answer.
Really impressive!
Impressive.
is that a 90k? how long was this cut?
wtf!!! nothing cant stop the waterjet cutter 😮
What was that about "the path of least resistance"?
what is it preventing to go trough the table ?
Good question.
The metal slats have to be replaced from time to time....and they can get as sharp
as a razor blade.
Water in the tank, distant and 1/2" thick metal at the bottom of tank.
It's all about about the power and weakness of water.
How long did it take?
would water alone ever work to cut that?
no
it's basically sanding it's way through the material.
How much to own a full machine like this
170k give or take.
is there a material that a waterjet cant cut?
Water jet can cut virtually any material. Diamond? If anyone out there cutting diamond please let me know.
Jewelry industries use it to cut gold, silver, platinum, titanium....
how does it not just wear itself out?
it does. The trick is is distant. it maximum cutting power is within 0.06" from the material surface. its power reduce exponential as distant increase. bottom of the tank is about 48" away.
do you know the kerf of the cut? looks like a 1/16 just wondering
0.015" to 0.06" depend on the nozzle used.
that is actually fucking insane
Beautiful work, I swore there would be swirl cuts down low but no.
There are still some at the bottom but it minimize by the type of garnet use and program control.
Hello,
How much do you charge per hour to the customer ? I want a average
I'm looking this technologie for a big production of pieces. 500 000 pieces/years
J-P,
Please send your request to rfq@schgo.com. I will response to you. Don't want to bore other people with business talk. Address to Yong Goh
Arethose rocks diamond dust?
river sand, it's called garnet
Most uses sand from beaches around the world. We use sand mined from mountain in New York. The mined garnet cut faster and produce smoother cut surfaces. It is 90 grit sand.
what is the cost of this machines
$250K more or less
Wow,
Amazing..!
Do note the video says "water and rock" (it adds abrasive / garnet). 0.04" x 2000 mph = 1 gallon every 5 seconds. Uses about a pound of rocks a minute.
1.25 lbs to be exact
Is it possible to water cut tungsten carbide?
Yes, it is possible with really slow cutting speed. Faster speed can be achieved by using Aluminum Oxide or Silicon Carbide as abrasive. However the mixing nozzle wears a lot faster.
How tight of a tolerance will it cut to?
depend on material type, thickness, hardness and speed of cut. Range from +/-0.005" to +/-0.030"
pressure how many?
Could any one pls tell me how fast (the speed ) it would be cutting the steel in terms of ipm or mm/min ?
it's very very slow. the thicker the material the slower it goes, takes time to remove the much material. You're essentially sanding it away. kind of like an EDM but much faster, not nearly as accurate though. EDM can do .00001 and this kurf is at about .04 so it's like the grand canyon compared to EDM.
Not possible (well, of course it is..). But my brain is still telling me "it's not possible". Clearly I need a new brain :O) Thank you for posting that.. Truly AmAzInG. Cheers
yes, just think about it is like a high speed sand paper that can remove steel at a layer at a time.
its like a belt sander except its moving at about mach 2.5
does the nozzle wear out?
yes, about 100 - 150 hours on use.
what was the kerf on those parts?
0.045" to 0.06". Our nozzle is 0,042"
I want to know the name of this machine please?!
The manufacture in Omax corporation in Seattle.
HHO Gas cutting torches cut faster than water torches. The power of HHO Gas is water on fire fuel technology that is a focus flame.
that may well be but, the water jet cut surfaces are much cleaner
Holy crap!
I think I speak for everyone when I say "I wonder how long that took" 🤔👌
4.5 hours.
What is the nozzle made out of?
Some type of sintered carbide Roctec 500. Typical last for 80 - 100 hours of cutting. our's norm is 130 to 150 hours.
DIAMOND, DUHHHH. IDK
How do you get that many hours ? Our Omax with the Roctec is good for around 20 hours before the abrasive eats it up too much and the jet stream quality degrades enough to warrant a change. @ $160/mixing tube management was not happy to hear that!.
Damn. Ours is low pressure. Thickest we cut was 4 inch and we had to tilt the fuck outa it to keep the taper straight.
Stainless steel plates up to 150mm you'll find at HW-INOX in Germany ...
Amazing
2:22 7 5/8" not 8"! Still Impressive as hell!
Mikey8567 you are correct sir. maybe 7' and 11/16"
whats the point of this jet?
for industrial usage to cut any material with various profile that is difficult to accomplish with traditional machining techniques. This is relatively need technology in cutting. Usage includes cutting meat, vegetable, jewelry, gold, stone....... you name it, we cut it.
Is that hinges for the door to valhalla or something? lol
Hinges ?
it is for industrial tooling
what i wanna know is what is that nozzle made out of? lol
Skookum as Frig!
focus you fack!!!
Son of a diddley!
carbide
how? why ? water?
Turn on faucet.
They do it because they can.
Ever hear of Holy water? This uses a variation called holey water.
great cut but not sure about precision, doesn't look like it can meet what needed for cnc
That shit's seriously that strong?!?!
Someone left the water running
Clickbait... it was 7 3/4 inches thick. hahaha Still quite impressive!! Although this is probably more of a roughing in process... what kind of tolerance can you hold? How straight did a cut that thick actually turn out?
Yes, the block is 7-3/4" thick. Good catch. But i have a 1/2 inch fixture plate underneath to support the block. It cut through both. The is very straight at the top. Tolerance about 0.05-0.10".
Name of song please?
Process very slow for cutting higher thickness plates
it must have taken 4 days.
4.5 hours
HOLY SHIIIIIIIIII
Разве такое возможно?
Titan submersible
But just because it's water, don't think it is safe. That water jet would rip through the flesh of your hand and arm like a flame thrower through butter.
crazy shit.
I would have cut that up faster with a nail file.
they should've just made the steel waterproof
This video won't play
Phillijr so does your brain
alice jeffy only sometimes tho
the steel was more like 7-3/4"...hmmm
yes, 7-3/4" plus 1/2" fixture plate at the bottom.
Wow! Then its cutting through 8+ inches of steel.
I also can't help to wonder how the machine handles that kind of cutting potential without destroying it's self... Hmmm
It is all about distant between the nozzle and material it cut. Cutting power decreased exponentially as the distant increased. Bottom of the tank is about 4 feet from the nozzle and it is only 1/4" thick. We added 1/2" thick plate to protect the bottom. Water and garnet dispersed wide and loosing cutting power as distant increased.
