- The process of making a giant hex nut. Most Interesting Korean Metalwork
Company homepage and sales site: map.naver.com/v5/search/%EB%B... - แนวปฏิบัติและการใช้ชีวิต
The main tool used on this factory is a metal half-barrel with holes.
😆
It looks, anytime it can shear.
Innovative
Cost cutting lol…
The holes aren't even cut in, they've been burned with an oxy torch.
'How was work today, honey?'
'Totally nuts..'
Seriously, this was quite interesting & seems mostly safe. Wouldn't want to be the threader & that seems like a lot of weight for a half drum to hold though.
In Korea, an average of 800 people die from industrial accidents every year in workplaces with less than 50 employees.
I love that they are using nuts everywhere as holders, spacers etc in the shop haha
Amazing vidéo, hard work and excellent workers.
Nice, these guys listening to classic music during the work.
Finally, a TH-cam metal forging video that doesn’t begin with shoveling dirty scrap metal into a cracked crucible to melt down. Actual quality control.
But I do miss the safety flipflops though.
@@patrickd9551 😄
ふ
Forging processes (like this one) just heat metal to the point it's malleable and then hot work it.. Casting is melting to liquid form. All steel processes start with melting and casting. It's not a "quality control" thing.
@@brian-px1bb It is.
Just melting scraps means you don't look at what you melt. Put some cast iron in there? Way too much carbon now. Put some steel scrap in there? Do you want pure iron after the converter processing?
Making steel is way way more than just melting some scraps in an oil fueled furnace somewhere in Pakistan
업무량이 대단합니다. 산업일꾼분들 존경합니다.
I love how they adopted unfinished nuts as supports in the machinery. Clearly was not designed and fixed by workers themself. 7:05
I wouldn't say fixed, but improved. Those plastic coolant tubes are missplaced easily when you accidentaly touch them with a nut or your hand. This way you don't have to readjust them so often ;).
Incredible video with fitting music.
I look forward watching 😊
Could you post a version without the music making it impossible to hear what is happening and ruining the experience, thanks
Now that's how to combine the machine sounds and some nice music and make a great video. New sub.
The final packaging in a bag randomly bundled spoiled the beauty of its manufacturing. I was expecting a beautiful box packaging like that of bearing.
thanks for showing the whole process
The classical music makes this really funny
Beautiful works, God blessed.
Great to see this!👍☘️
This seems so mesmerizing to watch. We look forward to watching more of these.
The word "mesmerizing" came to my mind too.
There should be an award to the first channel to figure out you don't need narration
Seems to be a step missing.. They get stamped with a marking after coming out of the shot peen, but the next time we see them, the ID has been machined. Cool video none the less.. love seeing these processes.
Between 6:05 - 7:20 you can see them being tapped after being hardness tested.
@@jimurrata6785 yeah but the ID is already machined when they get loaded for tapping. It's just not shown in the video.
Maybe those nuts were just reamed prior to being tapped.
That's shot blasting to clean the surface. Peening is a much more carefully controlled process than blasting, which is specifically to cover the surface in tiny indents and leave residual compressive stress which makes the surface resist cracks.
@@jimurrata6785 That's an ID stamp, not a hardness test indent. A Rockwell hardness indenter runs WAY slower than that, and low-grade fasteners like this are never 100% hardness checked. At best, they're checking 5 or 10 parts per batch.
Brilliant videos ! 👍
What a nice finish!
Amazing .Very fascinating.
Respect for all workers involved in the process
This is the best nut making video ever!!!!!
Agreed, I nutted to this
Like Pakistan's videos, but with new machines and clean and safe factories 👏👏
Amazing video. I love how there is no talking, nice music, and that you can just immerse yourself into the wonderful labor being done.
No music would be better
Wonderful labor or work that no one of us would be able to do for more than half an hour. Poor workers!
I would like to watch this video without the song
@@SecretPesch Easy--mute it.
@@SarahLowrey
No, you can't mute it. Then you will not hear the clink-clonk.
Music does not belong here.
На производстве без спецодежды, касок и очков???
Why is the scene where the inside of the nut and faces of the nuts being machined left out, this is after the letter punch but before the threading?
Thanks for sharing the video. I found it surprising how much labor and metal cutting went into making those nuts, would have expected it to be more efficient.
When you make 10 thousand a year of something you aren't gonna spend 5 million on an automated solution.
The big factories are for sure. They seem to be doing more custom or high precision nuts. No way this process could be cost competitive
@@acat6000 It's like 2 or 3 pounds of steel at 40 cents a pound. Those guys are cranking one out every 10 seconds. If it's like 5 guys working there among the different machines, that's under a minute of labor per nut, at 25 dollars per hour labor cost, which is high for Korea, that makes labor like 20%-30% of the cost of the material.
And even with a highly automated system you not only have to buy millions of dollars worth of equipment which the interest on cost as much as a few employees but you also have to hire a high skill automation tech with machining skills and programming skills and electronics skills and all that stuff to fix the machine.
It's not a question of precision it's purely a question of volume needed.
I like how they have classical music playing in the factory.
I think the music is playing in the video, and not in the factory. That is the case in many videos on this channel.
Muito legal!
Abraços...
I think working in a place like that would drive me nuts.
See what you did there
Next video: "The process of making a giant crescent wrench for the hex nuts we made last time."
It must so nice working there getting to listen to classical music while you do your job.
Did you see the conductor on the wide screen above the Row of Taps? Talk about Job perks.
Very nice!
This is nuts!
Для тех кто "фу, пакистанские технологии" такое количество (хотя вполне умеренное) ручной труд потому что с большой вероятностью поступил разовый или эпизодический заказ и делается ограниченная партия скажем в 3-5тысяч штук (сомневаюсь что именно в таком размере гайки нужны миллионами) такому заводу это на полдня работы, никто не будет тратить несколько дней на наладку автоматизированных линий. Учитывая широту номенклатуры крепежа это вообще риск непрерывно сидеть в наладке, вместо того чтобы привлечь несколько человек на перекладку и сделать партию за день другой. с метчиками там все хорошо, они специально обученные работают в СОЖ и полностью выходят. Внимательные заметили что (в ролике последовательность похоже неправильно смонтирована) гайки еще суют в ЧПУ токарный центр где их торцуют и вероятно еще доводят резьбу до номинала. не хайтек но современное и рационально организованное производство с вероятной специализацией на выпуск широкой номенклатуры крепежа сравнительно небольшими партиями. А бочки... нормальный подход учитывая специфику груза тара там долго не живет, делать специальную накладно в контексте того что количество бочек (из под масла и СОЖ) регулярно пополняется, делается элементарно, выкидывается вместе с отходами по мере износа аналогично, экономика должна быть экономной ))
В токарный ЧПУ суют не для доводки а прямо из дробеструя. И растачивают и режут резьбу. Мне тоже показалось, что торцуют, но нет, торец остался чёрный, с клеймом. Видимо партия гаек с нестандартной резьбой или часть метчиков вышла из строя. А расточку других заготовок под метчик не показали.
That is nuts!
This video is nuts
Wow, nice video, love it 💚💯🔥
I've worked with nuts like these we had them on large positive displacement fluid pumps
Nuts like deez?
@@GW71093 The really big nuts. You know.
Incredible precision
This job is nuts!
Неужели для цеховой тары не хватило денег - половинки бочек с рваными краями ?
- Можно было бы сразу в ковши перегружать - видимо ковш только один, нищеброды. )))
@@hztnэти полубочки всю картину портят, гайки вылизывают, а тары соответствующей нету
너무 멋지다
In al, of your Korean factory videos there’s a commonality to them all - those yellow plastic baskets and tubs. I hope the Korean who came up with them is now sitting there surrounded by lots of said baskets all full of Won and grinning joyfully. :)
bolt up is a good workout for the fore arms, especially if you dope them in -20c weather!
현대금속 다른 제품도 많은데 육각너트는 처음 보네요. 생각보다 품종이 다양하네요
그렇군요 감사합니다
육각너트 공장은 처음 보네요. 신기합니다,
잘 봤습니다.
시청해 주셔서 감사합니다.
Great video, good workers, but it would drive me nuts.
Great video but no need to add music
첫 직장이 이런 비슷한 공장이었는데,
완전 3D 직종입니다.
지금 직장은 공장 바닥에 그냥 앉아도
될 정도입니다.
30년 전 이야기 인데, 그래도 그때가
좋았습니다.
As somebody else has said they are missing a step. And also that bar is not the same bar that gets stamped the very first time we see it. It is a lot wider than when we see the man loading up the bars at the beginning.
I noticed that also!
maybe key step is not for open
I noticed that too. They're making at least 3 different size nuts in this vid. Similar process for all, but no, we're not following the making of one nut.
Теперь понятно, почему многие гайки с Азии невозможно качественно законтрогаить, особенно на вибрационных узлах.
P/S. для тех кто напишет, про шплинтование, обвязка, прихватка из сварки, гравера, специальной резьбой, где гайка за собой заминает резьбу и т.п. есть такие узлы, где именно удобство при замене, составляет контргайка)))
ИЗ Азии а нЭ С азии ) укр учи русский язык
@@TinTaBraSS777 Своих детей учи, человек замечательно и понятно пишет, не нравится - не читай.
И почему их невозможно?
Купи тогда гайки российского производства!
Вопрос-ответ))) И у нашего производства есть такие грехи, но меньше. Это проще понять, кто с этим работает или связывался. Проще конечно на рисунке об,яснить но) Есть различные углы на резьбе, их много видов и самые популярные допустим метрическая. И как показано на видео, нарезают резьбу обычным метчиком, видно что он свободно входит в шпиндель квадрата))) Углы не совпадают и при разной постановке его, когда обычно ты затянешь, да это будет держать. Но контргайка просто "приложиться" к гайке и не будет совпадения катетов углов на гайке и болте или шпильке. Это легко проверить, накручиваем две гайки одновременно и недолжно закусывать, появляться между ними зазоров, это будет прочное соединение. Я не токарь, я работаю с дробильно-сортировочным оборудованием, бывает даже немецкие шпильки вытягиваются. На класс прочности я бывает даже не смотрю, потому что 8.8 лучше держит чем 10.9, а про каленку, не скажу))) Ее не высверлить, небольшой загиб не выколотить, а в глухом отверстии не выдуть))))
A nice warm place to work ☺️
TOP 👍👍👍👍👍👍👍👍🇧🇷🇧🇷
i have a couple knives i’ve collected through the years and some are from korea they are great knives they must have good steel and good production value
King ji❤️you work so hard we love you and your content and don't let the haters get to you
Who is sending him hateful messages? I don't see a single hateful comment.
저런 큰 볼트는 어디에 쓰이는지도 궁금하네요. 신기해서 계속 쳐다보게 되네요. ^^

Shout out to the employee of the month: Half drum full of big nuts
That's nuts!
Sempre fui um admirador do processo industrial, são peças muito bonitas e perfeitas.
블라스트 공정부터는 작업인원 유지하고 자동화 개조하면 생산량도 늘고 좋을텐데 .. 손이 엄청 많이가네요
Totally nuts!
옛날 단조공장 알바할때 생각나네요.. 트리밍하고 나온 스크랩으로 담배불붙이고 했었는데..ㅋㅋㅋ
내가 예전에 현대금속에서 구매를 많이 했지만 지금 생각할때 너트값 엄청 받아도 괜찮겠다.
너트 하나 만드는데 이렇게 목숨 내놓고 수작업을 해야 되니 전작업 자동화 안되나?
너무 위험해 보인다.
볼트너트 열간업계가 항상 저렇게 위험하게 작업한다. 부산인들 대단합니다. 존경합니다.
소량작업으로 진행되어 전자동화는 불가합니다
What for a material ? How could you granted the specified heat number?
Solide Qualitätsarbeit.
Привет из Ростова на Дону🖐Cool👍
This was nuts.
столько много ручного труда . разве это южная корея ?
I wonder how they track the material and heat treat? It looks like they would come out pretty soft. They will be going into a bridge near you.
이렇게 재밌다니..ㅎㅎㅎ
I love all industrial workings this one with excellent music and all the background noise is just awsome thank you
Combined with the correct music, so satisfying to watch!
If I had to work in this factory with this background music I would go bonkers
Да, музыка супер. Обычно наоборот портит ролики, а тут даже интереснее сделала.
so cool, how are the small ones made now?

그렇군요 시청해 주셔서 감사합니다
It's interesting, some elements are highly automated while others that in theory could be automated are labour intensive. I wonder what the economics would be to entirely automate this process.
My theory is they process a steel of different grade. Otherwise it does not make sense.
凄い！韓国も最近ではナットを作れるようになったんだ！
キムチしか作れなかったのに！
At 2:13 for a moment I thought they were going to weld them back together as one long shaft
In Korean, bolt and nut is both called 나사(nasa), which is read same with National Aeronautics and Space Administration lol
탭날 뿌러져 있는데도 그냥 쓰네요.. 저래도 나사산 잘 나오는게 신기하기도 하고 ㅎㅎㅎ 모재에 박혀도 제품이 얼마 안하니 저렇게도 사용하는게 신기 ㅎㅎ
시청 감사합니다
여러 대의 탭 기계가 보이는데 이는 산을 여러 번에 걸쳐 내는 겁니다. 최종적으로는 CNC 머신으로 다듬는 것 같습니다.
Badass factory.
There are broken threads on one of the taps. How often are they replaced?
Couple teeth are not critical, of only they not cause jamming. Some break cases may be regrinded. Next tooth after broken have to take more chips, that's all.
No idea how often the're replaced, havent worked at a line, but only suppose that couple in a day.
I noticed that as well.
@@hztn Maybe the threads are so large the chips come out without jamming. I couldn’t see using a tap with smaller diameter and tighter pitch with missing tap threads
The guy who full time puts the nut in place for the tooling stamp lol
Thats just nuts.
Always a good idea to check your nuts
That does look very good quality!
It's not lol
Interesting way to load the taps.
저런 큰 볼트를 사용하지 않지만 책상에 장식품으로 하나 두고 싶네요
I do my best thinking when I'm fidgeting with my hands. A huge bolt and nut on my desk would be perfect.
Is it just me or did those pieces almost dbl in size after going through the induction heater??
Поставил девятый лайк.
What factory was this?
... Induktion the best fire for ready Metall forming.
А где процесс расточки? После клеймения идут кадры с расточенными под резьбу деталями.
Wow, those are some BIG nuts man 😂😂😂
