'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.
Finally, a CZcams metal forging video that doesn’t begin with shoveling dirty scrap metal into a cracked crucible to melt down. Actual quality control.
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
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 ;).
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.
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.
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.
@@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.

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.
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 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)))
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))))

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.
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.
@@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
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. :)
@@richardschipper5989 nope carbon or alloy steel nut forging use water for cooling die that answer is correct. Stainless or nickel alloy(ex.inconel,monel,hastelloy) using release agent (water bond).
While I love watching the process, I question the quality control in that place. If you watch the close up of the tapping operation they show you a tap that has a tooth missing for one turn of the tap and then the next close shot is a nice new tap, the shot after that shows multiple taps in the machine missing multiple teeth.
if the last few teeth are intact its irrelevant in what conditions are the leading teeths and the tap is guided so you cant get misalignment cut. Taps even in daily use last for years.
Among videos I have watched, this nut manufacuring system doesn't have an automation process. Is this because labor cost is cheaper than adopting modern process?
И это промышленно развитая Корея? Бочки из под масла с дырками используются как тара в производстве, множественное ручное перекладывание "от сюда - сюда", никакой автоматизации производства. Скоро "разовьются" до уровня Пакистана.
I guess they wait for those taps to be totally shot in the threading department. Most were missing a few teeth, but that one at 7:17 was missing most of the tapping threads!
I was impressed that they ran the whole tap through the nut and let it drop out the bottom for a manual pick up. They use all cutting surfaces of the tap.
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
I actually worked in a factory that made aerospace bolts once. After 3 days I got heatstroke and had a nervous breakdown. I don’t know how they do it..
The main tool used on this factory is a metal half-barrel with holes.
😆
It looks, anytime it can shear.

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..'
