Here is the link to the giant gear video that I mentioned ruclips.net/video/L9QyAXxKvaM/видео.html
What are gears ⚙️ this big used for or used in/on?
In a world of hurt...15 minutes of wonder. So happy.
@@Phillijr100 power plants, large industrial factories, large ships, etc.
That was an exceptionally good video. Give some compliments to your friend!
So... The Nitrogen will actually work as a protection gas?
We use nitrogen as protection gas in ours bell oven annealings when we softening coils from our cold roll mill.
Ohh... And in some of the ovens we use hydrogen as protection gas.
I know they probably don't get as many views, but these machining and metallurgy videos are excellent, especially in 4K!
Agreed! These are as good as the explosive videos.... and I
Thanks to subscribing to this channel a while back I've been getting so many videos like that and since I'm a hobbyist machinist I love them
Some of this type of videos Lauri has posted on BTP have several hundred thousand views. They tend to do very well, even if it takes a while to build up the view count. They always tend to have very supportive comments too.
You also never know who might be inspired to learn more about it or even enter the career as a result of watching these videos!
@@Ultimaximus a few months ago I got into lock picking by watching LockPickingLawyer LockNoob and BosnianBill and then because I wanted to make my own lock picks especially the detainer pics I decided to get a lathe and then I went all out and got a mill too 😁 nearly forgot about picks but I love the machines
Dude was great. He should be proud of what he designed.
Yep Tami was really good on explaining how this works
Thanks, this comment made my day!
@NVD DVN Thanks!
I'm only 4 minutes in but I already am incredibly impressed with the thoroughness of this guy's knowledge and ability to explain everything.
And in perfect English.
I guess that's why he ended up becoming the sales director of the company :P
@@Taizunx What a waste!
I worked in a steel heat treatment plant in the US and it's shocking how much cleaner and better lit the Finnish plant is.
I worked in one last week, my end if the day shower looked like ink was being washed off.
The lighting, but I noticed the floor too!
There might be some nice ones. I've been in machine shops covered in cutting fluid and chips, dirty, poorly lit hellholes. I've been in machine shops that are similar to the heat treatment shown in this video. Well lit and clean.
I have a theory that involves plant management ...
I think it depends on the age of the plant.
I've been in an old German plant.
You could see the building style was 50+ years old, and you could shovel wheel barrels full of dust each day.
@@jonanderson5137 Or unions that actually do something instead of just take your money...
Honestly I think it's more a matter of the age of these facilities, though. And maybe the culture surrounding them. Everything in Finland is disturbingly clean. It's near liminal space sort of clean.
@@scorchedearth1451 I've been in old buildings where the timber is about 2x4, not stick 2x4, I mean 2 feet by 4 feet and the columns were 4x4. Clean. Machine shop.
Age has absolutely no affect on good shop practices. Management has to decide if they want giant bonuses or just bonuses. You have to maintain and service dust collection, all the HVAC etc.
This is basic stuff.
Well, looking at the exhaust soot from that quenching tank it's obvious the soot will accumulate on surfaces and some of it will stick there as time passes. I wondered why there was no some sort of ventilation hood on top of that sucking the exhaust away but I guess the answer is cost.
I really admire Finland for focusing education on trade skills.
This stuff is closer to material science engineering than trades, something you learn at a proper university rather than a trade school.
That makes sense.
@@jamesharding3459 Yep you learn this kind of stuff at Tampere University of Technology
Can we take a minute to appreciate how clean this facility is? Considering the work being done, it is remarkable how even the ceiling is clean. That speaks volumes about the safety standards of the company that runs this facility. If this was "made in china" there would be an inch thick coat of carbon dust on everything.
Love some giant engineering stuff. Also these dudes explaining something in their non native tongue better than I could as native english speaker lol
He was a some sort of sales manager and as Finland is such a tiny country we must be able to sell our stuff to foreigners. So, you have no business if you don't know at least English these days. For Finnish businesses Germany is also a big market so English is not the only language people learn.
Well done. Excellent presentation. Interesting and instructive. A person't understanding of a topic is manifest in their ability to explain it.
You were right. It IS the nicest heat treatment plant I have ever seen.
........
While it may be the only one I've ever seen, it truly is the nicest. :)
your friend saying "hello" gave me a chuckle as it reminded me of anni.
Ive been really hoping someday one of his guests would say "And Im Anni" 😂😂😂
Holy shit, you guys speak such good english. Technical and articulate! I. Love. These. Channels!
As an amateur blacksmith and machinist, this literally gets my heart beating fast!
Wow, that guy explained things so well. This is actually one of my favorite BTP vids, so interesting. Pretty good!
Thanks!
@@tampuriini87 Mate, you were more interesting, informative and eloquent in a second language than most people manage in their native tongue. (Particularly native English speakers.)
Take a bow, you did a difficult job extremely well!
@@DrBunnyMedicinal Thank you, very kind compliments!
It's kind of amazing that humans went from bashing rocks together, to machining stuff like this.
I love this kind of video. When I was a kid my dad used to let me stay up really late at night sometimes to watch the Open University on the BBC (in England). They had all kinds of physics, chemistry, and engineering programmes on, and I couldn't get enough of the machining, metallurgy, forging, and materials-testing stuff.
Unfortunately it was meant for university-level students, so there was masses of maths, technical data, chemistry, weird physics formulae, exam questions and hard work as well. I didn't understand any of that; I just liked seeing things being designed and made.
Thanks for this, Lauri. It reminded me of some very happy times with my late dad. It also reminded me of just how stupid I grew up to be... 🤭
I love to see what a modern heat-treatment shop looks like. Very good.
Amazing technology. Imagine what a engineer from the 1800s would think after seeing a part like this. Thanks Lauri.
Well they already had giant machining in the 1900's eg those gaint steamengines used in ships but also in other factories. Power generation just benefits lots from scaling it up. I think he would be most amazed by the amount of precision we can achieve now on this scale. That took a lot more time back then.
@@Torchedini they had nothing like this.
@@donniev8181 I think the process would have looked largely familar to engineers at the end of the 19th century, as case hardening large chunks of steel for battleship armour was quite popular at the time. The precision and automation however would be incredibly impressive.
@@tiktian the automation was not available in the 1800s, what is wrong with you people?
@@Torchedini the automated process was not available.
Rittal cabinets, Siemens panels, Janitza energy meter... this looks like most of the plants I've worked on in Germany. Nice to see some familiar parts!
Romanian machinery but with tons of German parts...
I know these videos are not as popular, but I really enjoy them.
Brilliant video and very educational! Would be great if you can do more like this.
I love these heavy industrial videos. That process certainly beats using case hardening compound for case depth.
"But don't tell my wife." So far, there's only 10 dislikes. But 9 of them are from his wife.
Having watched a bunch of USCSB videos, so glad to see PPE on top of whatever sensors are in the building
It is like a "how it's made" for stuff you didn't know existed. Very interesting.
I love these machining videos - please do them more often.
Tami is such a nice guy. This is a great, educational video.
Many thanks for this very interesting video. Yes to more of these types of video please. Kind regards, and greetings from Africa.
Thanks to both of you for the tour! The instrument for centering the part on the lathe is called a dial indicator, but I heard someone call it a touch clock which seems more elegant.
Sometimes also called a "Runout Gauge", depending on usage.
This is the first time I heard Lauri speak (briefly) about when he was younger. It must have been interesting growing up in a machinist family :D
"This is probably the nicest heat-treatment plant that you will have seen"
Well, you're not wrong Lauri.
This is awesome. Thank you for sharing.
On another note, I'd like to mention how impressed I am with your English. I'm fluent in several languages and couldn't say chuck in any of them.
Thanks again.
This is fascinating, thank you for all of this. Your friend's explanation of the process was very useful and well done. Please show us more things like this when it is possible.
A megawatt used to sound like a lot to me... now I'm dealing with printing machines which have a total of around 3MW heating power each, one of them has 16 burners totaling to about 10MW
Printing what exactly?
@@pancake_crab4457 decorative paper, mostly for furniture and doors
A steel mill can take something like 400MW to melt a pot of scrap so yeah, there are numbers and then there are big numbers. 1MW doesn't yet make you think a lot about how much the electricity bill is but with 100s of MWs you might start to plan at which time you're going to use the energy.
One of the best parts about these videos is listening to people speak better English than plenty of people that speak it as there only language...Bi-Lingual FTW
I learned basic machining back when I was young. My father taught the subject at a college. I love to see these big machines making parts like this. Keep doing these!
I've been fortunate enough to work in or visit a lot of different heat treating operations, and that facility is both 1) humongous, and 2) super clean. Awesome video!
Hi Lauri. fantastic stuff many thanks to all concerned.
Endo gas comes from an endothermic generator, which uses natural gas. It is cheaper to convert natural gas through a catalyst than to buy methanol.
Also methanol is a bit dangerous since the flames are invisible. Case hardening atmospheres are almost always a dangerous: Ammonia for nitriding, carbon monoxide for case carburizing, or acetylene for vacuum carburizing.
And then there is Dan Gelbert using methanol in his home heat treating furnace.
@@kurtu5 His method is probably one of the safest ways for a carburizing atmosphere on the small-scale. Very minimal risk of injury from an explosion that way.
Interesting topic, and Tommy speaks English very well.
What clear and excellent explanations! This is a state of the art facility. Thank you both!
Hello from Japan! I'm watching from years ago, and I saw you guys in Itte Q! Pretty much big project that you do! Keep your work and your body the best! Love you
That guy speaks excellent English. Awesome vid as always!
I love watching these big industrial machines work, and the great explanation that Laurie and Tommy gave.
Awesome video. Your friend’s explanation was brilliant!!! Thanks so much for sharing.
This is a terrific technical video. I love these
"We have here our little barbecue machine." :)
That was incredible to see all around. I'd love to see more like this.
Great video and excellent description of the hardening process involved. 👍
Fantastic video! I really enjoyed seeing our gear friend complete his journey.
Fascinating. More of this type of video please.
7:15 That looks mesmerizing...
As a Journeyman Machinist these videos are excellent! I was exposed to heat-treating on my apprenticeship, not doing it, standing back and watching the experts work. It is fascinating to watch. And the way it transforms the metal, down to the grain structure, down to the molecular level is just amazing!
Very cool seeing this process.
I really like these technical videos. They are very relaxing to watch. Please keep up the educational content!
Very interesting - would love to see more like it!
Thanks. 🙂
I know nothing about this topic, l know know more than I did and found the content interesting. Thanks for sharing
Those tolerances on parts that big is mind blowing. Very cool!
Excellent episode, guys!
Really loved this video and explanation of the process.
Beautiful work. Thanks
Very interesting! Many thank to everyone involved!
When they dropped the gears into the oil bath, I had a flashback to Han being encased in Carbonite.
Lol
Really interesting! I had no idea so much went into making big gears!
I like how the fork lift starts moving before the furnace is fully open.
Smart programmer. Cutting a few seconds off the cycle time is usually a good thing.
Really awesome video!
Thank you so much for the effort - it was fascinating to see the massive production scale, heat treatment and machining.
Wonderful and I'm sure we would all love to see more fascinating videos like this one, whenever possible.
Man I definitely want to see a video on the large tools you have back at the shop!
Really nice and interesting!
It's also quite satisfying too see such large pieces, red hot. And really impressive that they can make such big parts with such small tolerances :)
It's insane that an overdrive gear can be that big. I've worked with hundreds of gear-reduction systems (less speed, more torque) that were comparable to that in size, but never an overdrive system.
Wonderful explanation of a very interesting topic
This is a great explanation!!!
That was really interesting. I would love to see more.
Thanks so much for reaching out to your friends to film this for us and taking the time for presenting it all! The modern world wouldn't turn without engineering like this, hopefully it's inspired some future engineers!
Wow I did not know that you could carburize steel using gases awesome I've been practicing as a hobby machinist carburizing my own tools and parts by packing them in pure carbon and roasting them
Maybe its just an issue of cleanliness. Rather than having a giant tank of hot powder/sand to mess with, clean, etc, you have carbon containing gasses. Which wouldn't be feasible on small scale, and vice versa for the large scale. I would be interested to find out if thats why
@@skeetsmcgrew3282 I'm sure that's why.
it seems it takes a lot longer when using gas as well the electric/fuel bill for days to a week is another thing a home shop cannot afford. It said it could take days to a week for like a millimeter or two I think, well when using carbon powder you can go deeper than that in 20 minutes
@@Vinlaell Literally can not go that deep in 20 minutes, the diffusion doesn't work that fast. Mostly the limit comes from the temperature that is limited to certain degree to not fuck up the hardening (higher temp, higher diffusion rate). As for case hardening, usually it is given in the blueprint what the depth actually means, but generally speaking a case hardness is measured to a depth where the hardness goes down to 55 HRC IIRC (might have been 50 HRC). I'm quite sure you are not measuring case depth at home.
Doing it with gas is more consistent and uniform compared with using solid carburizing agents. Which is more important for industrial applications.
Thank you, this was really interesting and educating!
It is always interesting to see how things are made.
Keep up the great videos.
This is an excellent video. Nice job.
This is awesome! Thanks for sharing
Fascinating video!
I love these technical videos. I would love to work in a place like this.
Verry interesting video. It's insane that it is possible to machine something that big with that persicion. As I demanded already for the first giant gear video. Pls so follow up as it gets installed. The turbine gear box is very interesting in its own i guess. Nice vid thx
A cup of coffee and giant gears, a good start to the day.
Great video and very informative
Holy smokes, now THAT'S a lathe
I see the gears for my watch is coming along nicely :-)
really interesting more please Lauri!
Very good video and great explanation by that guy 👍.
So well explain plus his English is perfect ..well done clearly this man is very very smart ..
Great explained 👍👍
I really like these type of videos you guys do.
This flew by, so interesting
This reminds me back when I worked for mfg company, it brings back memories!
Greetings from Canada!
Wanted to add a comment about all of BTP episodes on the frozen lake to a new vid
All the fish in that lake are like
"Don't F***in go over there or you'll die"
Love the channel, Became a member and i'm hooked on it.
Great jobs everyone involved.
great vid thanks and greetings from the NJ Bayshore
Clean shop indeed!
You earned my subscription just for the Belzebubs shirt, great band🤘
Love the Belezebubs t-shirt!
Cool process to watch!
I really like this video. It was really interesting and educating. Learned alot from it. And,, it gave me some ideas on a certain gear that im working on. Thx guys!
Awesome video
