Cut... Lets try that footage again. And again. And again. I think we could make this a drinking game. When you see the cut during the field guys description you have to take a drink....

[@kennethfharkin]

Here is a little story from Switzerland that happened about a decade ago. Shop full of Swiss lathes working Ti lights out. Fire starts and extinguisher goes off EXCEPT the fireball blew into the ventilation ducting which connected all machines. First machine is extinguished but the fireball begins to ping pong from machine to machine, each time extinguished UNTIL... it gets back to a machine whose extinguisher was already exhausted. One less shop in the Jura.

[@353Tensa353]

Well i guess fire baffles would be a priority in the rebuild, but damn that sux

[@kennethfharkin]

@@353Tensa353 Damn straight. Switzerland is a small country and news travels fast. Many people took a long hard look at how they baffle the ducting after that. They did rebuild and everyone learned an important lesson.

[@Kevin-fj5oe]

Well, nobody gonna expect that shit to happen

[@353Tensa353]

@@kennethfharkin well i guess alls well that ends well and as i was in a similar field the industry uses "accidents" as training and learning tools to make everyone safe so i guess its all good, just hope no one was hurt

We just lit a machine up two days ago. Yippee. Oil is still the best though!

[@williamlind2843]

Oil is KING!! Hell on laundry!!! Don't get your girl's best dress mixed with your shop pants!!!

[@stevehayward2533]

In the old days, we used to cut aluminium with a paraffin based lube. The machine was surrounded with fire extinguishers, as catching fire was a regular occurrence lol.

[@backtoearth1983]

Who thought that was a good idea? What company was it, ACME?

[@softyzz69]

That is one of the most awesome things I think I have ever heard myself read lol.

[@tobbleboii5988]

I'm usually using alcohol when i'm grinding carbide or hss manually had no problems so far, but i did light my fingers on fire on other occasions. Alcohol burns somewhat cold, would not reccoment still

[@LordOfChaos.x]

Me when milling Magnesium

[@ErikTheVikingMechanic]

I would say no more jump cuts next time. It really makes this otherwise good video looks like it was pit together by 15y old

[@The_Collective]

I've actually seen this happen twice, but they shot a nice fireball out of the top before being extinguished. Still operational.

[@jamesbarker925]

I ran s20/25 older versions of this and we worked to submicron tolerances for the last 20 years now unemployed :-( The thing you don't mention is these are for grinding hardened/heat treated materials soft metals clog up the grinding wheels. Watch out for vibration and wheel balance! we used these to 'match'(make them fit together) Injector valve guides to nozzles for diesel fuel injectors, also the s25's cut the multiple angels on the pointy(seat) end of the valve. The repeatability was amazing even 20 years ago, if monitored, as cutting to sub micron tolerances was badly affected be environmental temperature changes, for instance from nights to days temperature variation had to be taken account of in your SOP's, or you were quickly making scrap, unless you have the machine in a temperature controlled environment, which only a few of our machines were, I was the manufacturing Craftsman on those machines and others.

[@user-jt5vm3mi1w]

why unemployed

[@jamesbarker925]

The repeatability on these machines is only as good as your measuring equipment, that needs to be up to scratch, and have repeatability studies done on them, that's really important at sub 1 micron even above that, you cannot have the machine with out the measuring equipment which can match it, this is really really important.

[@BorisSpark]

Well better be safe than sorry, seen a whole shop go up in flames, sad to see it happen.

[@kurtlarefsane2271]

please can you broadcast your videos with subtitles

[@victorschreijen6460]

You should be able to have KZbin put subtitles up for you. Tap on the running video, at the top right of the screen you see a little square with cc in it, hit that one and BOOM! You have subtitles😏

[@danl.4743]

@@victorschreijen6460 It's more like POING! not BOOM!

[@Rob_65]

The first five seconds I was thinking: First a broken water line, then the snow storms and now this 🥺 Good to see that this was just an example of what could happen - not what has happened. We actually built something similar in our CO2 laser cutter: two IR sensors detect flames, stop the air, move the laser-optics away and sound an alarm. We never run the laser when there is nobody in the shop so we just have a CO2 extinguisher next to the machine.

[@williamlind2843]

LOL!! Me too!! In 30 years the worst mess I had was a hose siphoned off 55 gallons of Blaser on the floor! I made my guys mop it up and use it!!!

[@weldmachine]

Who came here thinking this was going to be some Bullshit video ? At least there was a point to this Bullshit Thumbnail. Still curious how this machine will operate in an ambient temperature environment. Maybe that is what 1.7 Million buys ? A nice comfortable environment for the machine to live, LOL.

[@bocan3189]

Ordinary people: Let's buy a $1.7M metal cutter and use it like a surgical instrument... Titan types: Let's set a $1.7M metal cutter on fire. Legend!

Walter/Anca operator reporting in: We average a machine fire at our shop about once every 1.5 years. All it usually takes is a fire suppression refill and the grinders are up and running again

[@andyvan5692]

one point, this isn't just for oil fires, how about machining magnesium, ie mag wheels, in 1950's era mill videos that what they had to deal with (but using a bucket of sand to extinguish it{Mg is a reactive metal which can ignite by touching water})- we still have to machine materials like this today, so worth it to be cautious, esp. as the guy from Titans of cnc says these are worth $1.7Million each, and that's assuming US dollars, try this conversion to AUD, will make ones' eyes water.

Personally , I like to have BIG ASS CO2 bottle very near also . Fire extinguishers are like sex , SIZE MATTERS !

[@GraditelMacedonia]

Ok. Nice, but i have one question, does that beautiful grinder has sensor and alarm for empty or shut off CO2 botle?

[@dannybartlett4225]

I want to no what operator leaves his machine while it's running especially grinding 🤯🤮

[@rfengr00]

I wonder if you get the same problem with alcohol cooled machines? I have used a squirt bottle of isopropyl as coolant and it always makes me nervous.

nothing came out though ?

[@Dumascain]

YAY!!! The sensors and buttons work... what about the actual suppression system?

[@hyperfluff_folf]

That surely will be tested seperately Like pressure would be most likely given via pneumatic air and then its checked if all valves and nozzles work

I ran Studer S20/25s for 20 years for Delphi automotive, give us a job? Plant in UK shut down and moved lock stock and barrel to Romania(well over a thousand bits of machinery/plant), we were making big profits but the EU had other ideas!( open bribery of Delphi with incentives to move existing production to eastern Europe, spreading the wealth out.). Never had a fire in a studer grinding with oil coolant, but other machines did burst into flames, but we had same systems as described in this video, very reliable as long as they are maintained.

[@popanollie1]

crazy i never knew the cutting fluids were flammable, i used to work at a small cnc repair place and would deliver cutting/grinding/hydraulic fluids for them, the owner of course told me they were non flammable

[@Gollammeister]

The faster a fire is detected and the faster a suppression system kicks in the less damage risk to property and staff

[@williamlind2843]

CO2? Why not Halon? I have the system for my sinker EDM machines, but I use Halon. Only active in "lights out" scenarios.

[@rexoliver7780]

Halon can form toxic and corrosive gases after they put out a fire.CO2 is less dangerous to personal and equipment.

[@gabrielecossettini2923]

Just writed a guide on a dire suprression system similar to this one but equipped on a diesel heavy shunter locomotive who services here in Italy. You need to test those kind of systems at least every 6 months. 8kg of fire extinguisher can easily stopba starting fire in the engine room.

[@user-jt5vm3mi1w]

Daily testing is legal requirement in Finland

[@Sattkopf]

what advantages does co2 have? wouldn´t nitrogen be as effective but safer?

[@norbertfleck812]

You can store CO2 as a liquid at a pressure of 5 MPa (50 bar) only.

[@norbertfleck812]

@@soundspark Yes,, when expanding, it cools down to approx. -80°C Also CO2 is pretty much heavier than air, so it gets sucked into the fire instead of drifting away.

[@stevematson4808]

Titanium?

[@norbertfleck812]

Once lit, Titanium will keep burning even under a pure CO2 atmosphere, producing unbelievable amounts of soot.

[@danl.4743]

I thought the sensor is an IR sensor, called a fire eye. Hmm I will have to look into it.

[@HolzDennis]

Smoke a Cigarette and the machine thinks everything is on fire 👍🏻 Great idea 🤷🏻‍♂️

[@norbertfleck812]

A cigarette is not a problem, but the flash from a photographer can easily trigger the fire extinguisher. However, you should not smoke on the Shopfloor.

[@softyzz69]

Should have tested full scale! With CO2 hooked up and flowing to make sure there were not any problems. But hindsight is always 2020 lol, damn we need to change that number.
