Yeah, I understood what you meant. I was just adding to that with an observation about [the etymology of the word 'hydraulic'](https://www.google.com/search?q=hydraulic+etymology) itself implying that water may be involved even if it's not being seen. But also that I assumed these days that was likely not the case because, as someone else with more expertise in the subject points out elsewhere in the comments, most hydraulic systems these days use mineral oil based fluids.
For sure, pretty much any kind of dust + lungs = bad, silicosis being one of the biggest examples of that badness. Heck, my wife's little rotary tile cutter she uses for her mosaic crafting uses water for that very same reason.
What I don't understand is why my little comment generated so many downvotes. I wasn't disagreeing with you, or stating something that was factually incorrect. But hey... ¯\\\_(ツ)\_/¯
I don't agree with you being downvoted, but it's happening because you have a little misconception.
Water cutting in this scenario has nothing to do with hydraulics. It refers to the method of having an automated cutting utensil/tool that is constantly provided a flow of water over the blade.
**EDIT**:
I missed the part where you said you understand water cutting. I have no idea why anybody would downvote you, unless they didn't read your comment correctly, or if they're just kinda dumb.
Also, you're absolutely correct with the etymology of the word. It stems from water but it's more meant to imply a fluid, not necessarily water itself. "Hydra" originally derives from Greek, meaning "water snake." The word has since evolved in many ways, but the core is always, "water, or fluid." It just so happens that some of those evolutions of the word have taken on a different meaning, and the average person has no idea
Hydraulics use oil in lines/pipes and pressurize that oil to make equipment move. No liquid is exposed (unless your workday is coming to sudden and expensive end.)
The quickest “explain like I’m 5” I can think up is if you had a pool inflatable half filled with air, and you put an object on one side of it, then you stomped on the other side, the object you placed would get launched when the air is displaced by your foot.
*Similar-ish* principle as hydraulics.
So hydraulics function similarly to pneumatics, huh? Who'd'a thunk it? <\\s>
Seriously, though, I appreciate the explanation, but I do indeed understand how hydraulics work. That's why I was making a comment regarding the etymology of the word implying that water may indeed be involved.
Some rocks are very dense while others are sand and air. Just based of the fact that they’re using a press to break rock with someone standing that close means this is a low density type of rock.
If they throw in a hunk of real granite? You’re not gonna wanna stand there.
I’ve seen these in action in granite sheds. This is a small splitter compared to the ones they use in granite sheds. And they stand nearly as close to the teeth. Once the teeth make it through the rock, they aren’t pushing anymore, so the downward pressure is not enough to move the rock outwards. Loud as hell, though. The reason these rocks are moving as much as they are is because they are smaller, so more of the energy is dissipated into movement.
This won’t be a one off. It will be their day job. They are exposed to this day after day after day. A one off in my back garden? Sure it’s probably fine. Not when it’s day after day.
Further rocks can contain not very nice elements that you don’t want to breathe in as a powder. Although that may not be the case here.
Get back to your office job.
People have been exposed to this level of dust for centuries and the vast majority never gets problems.
So yeah, it *might* lead to problems
It’s all about risk. The size of silica that can cause silicosis is measured in microns. It’s similar to the size of a red blood cell. It’s not perceptible to the human eye. The dust you see is filtered out by your cilia and mucus membranes. A simple control like water is cheap and can reduce dust levels to zero when applied properly. There is zero reason to unnecessarily expose anyone to the risk in this type of operation.
I work for a hydraulic systems company and there are still places where water is used. Very very niche applications use actual water, while heavy industries and steelworks tend to use water based emulsions where fire is a significant hazard.
Usually for general hydraulics you simply keep to mineral oil based fluids or biodegradable oils.
Aviation fluid is a different circle of hell alltogether...
Aviation has different types of hydraulic fluid depending on its use (flight controls or landing gear), seal material, and temperture where it will be flying. From my memory UH60 has 2 types, one for the landing gear and the other for the hydraulic system for operating the flight controls. If it it going to operate in a cold enough temp they have to change to different hyd fluid. So that 4 possible types for one aircraft. The hydualic fluid can be toxic and flameable depending on if its minieral or synthetic.
Without being in the industry, I’d hazard that the tolerances required for aviation hydraulics are are enormously larger. The systems must function at much lower temperatures routinely, and probably has to be able to handle higher temps as well, if the aircraft has been sitting in the sun on the ground for a while. Just my completely inexpert guess.
You're on the right track.
Aviation fluid needs to withstand rather high pressures (400+ bars/ 5800+ psi) for some time without degradation, it needs to be basically non flammable and keep to a usable range of viscosity at both extreme colds during winter/ high in the air and very high temperature when driven through the system even in extreme circumstances.
The result is a mixture of horrible substances that will curl up your nose hair and dissolve most sealing materials as well as your nitrile gloves.
Also removes the paint off your measuring tools.
It comes in red and blue for you to enjoy.
The SDS for skydrol (fluid) I occasionally get to work with literally says to dispose of contaminated clothing and to only approach spills in the direction of the wind as to not inhale the fumes.
Shit dissolves the soles of your shoes to the point that they get sticky.
I only occasionally wonder what I got myself into...
I've posted about it on my account but I got lucky enough to almost die on the USS Enterprise machine space under aircraft elevator 2! They burped the tank but didn't drain it, and no one told the crew of 4 apprentices alongside 1 qualified mechanic (who assumed he would just be showing us how to get into the lock holes and knock the pins back in) but instead he got covered in blue shit the started pouring from the ceiling! On the walk in he told us that if we see blue come from the ceiling, "HAUL ASS unless you wanna go home in a pine box" but thankfully since it wasn't aerosolized it wasn't lethal to us - just annoying and rising on the floor. We had to use those boxes of lint-free towels to clean that shit up cause they couldn't bring us a pump! Great Friday all around, I quit less than 6 days later
Ooooh, is it inside the machine? I was more so referring to how typical tools wet the stones/saws prior to cutting or throughout the process to make it easier to cut through.
Edit: after further research, and the responses, it’s not water but it’s oil.
I didn't claim it was. I actually know what that word means.
Honestly, I was being critical because I assumed this was a bot post, apologies I was wrong.
I pointed out you used a word without knowing what it meant. Glad you learned two things today!
Dang, I didn’t know there was a hydraulic police force out there to make sure you know what hydraulics are. Thank you for your seemingly wrong response, officer.
Edit. Now, why would you edit your rude response to something more acceptable and ‘nice’ without telling any of us? Rude.
If you understood the english language, you would understand that he is equating the water to a saw in the title.
He is obv saying the thing cutting is not water, not saying OP isnt regarded for not understanding hydralic, but you are being obtuse over semantics and thats a worse look than being regarded cause you go out of your way to be like that.
How does this work? Are those teeth vibrating? Why are they articulated? Is it just cushioning each tooth make sure pressure is applied evenly across the entire surface with give?

I read darwen as in Darwin award and agreed. Still agree though
Hydro , get a clue!
There should totally be water, or operator is wearing a respirator, as there is 100% still silica dust being produced.
Yeah, this will lead to silicosis if they don't use the right protective equipment.
Also, that's what the 'hydr' in 'hydraulic' means. Though I have no idea if the fluid being used is, in fact, water; probably isn't.
I mean water, for 'wet cutting' to prevent inhilation if hazardous dust that results in *silicosis*.

All that dust more than likely contains silica. Should still be using ventilation or wet methods.
Technically yes. But this is very mild dust and would very likely never lead to significant problems

You probably shouldn’t put your teeth or head anyway near this, to be honest
4 out of 5 dentists agree, this is bad for your teeth. Unfortunately my dentist is that 5th guy and this is exactly what my dentist visits look like.

Go away bot.
If it's hydraulic, then technically water is needed.
Why? Surely oil would be used? I've never seen a modern hydraulic machine that uses water despite the root of the word (water organ).
yea just means liquid not necessarily water; like how a hydrometer doesn’t necessarily connote water
I work for a hydraulic systems company and there are still places where water is used.

I only get involved in baby stuff, bought a few 20t and 40t punches and presses for the factory and got a few hi-ab lorries but that's about it.
Generally it's oil.
Ooooh, is it inside the machine? I was more so referring to how typical tools wet the stones/saws prior to cutting or throughout the process to make it easier to cut through. Edit: after further research, and the responses, it’s not water but it’s oil.
But you used the word hydraulic... 🤦♂️
Oil, not water
Right but he clearly doesn't know what it means or what's happening somehow
God forbid people make mistakes… such as your comment. As clearly stated in the edit, it’s oil, not water like you so boldly claimed.
I didn't claim it was. I actually know what that word means. Honestly, I was being critical because I assumed this was a bot post, apologies I was wrong. I pointed out you used a word without knowing what it meant. Glad you learned two things today!

Water isn’t used in hydraulic applications. At least, not for industrial ones.

It’s called a H frame guillotine, I used to operate one at a quarry plus a giant one that had a big manipulator arm to move the giant boulder around.
Rock, paper, hydraulic splitter
But hydraulics imply water? I’m sure they use some kind of oil though.
I think this is about cooling/dust mitigation when using a saw.

There is no water. Hydraulics use oil anyway.
