The manufacturing process is great, but would be nice to see video footage of how the items are used.
Used for guide bushings primarily in metal stamping dies and other industrial plant machinery in the manufacturer of automotive and equipment parts, etc. As a tool and die maker, we use these by the thousands
@@treemanclint2883 why they cannot use grease or oil and why do you have to use that many do they wear out quickly ?
Thank you.
ChatGPT:
Guide bushings are cylindrical components that are commonly used in metal stamping dies to guide the punches and dies in the stamping process. These bushings are typically made of hardened steel or other materials that can withstand the high pressures and forces involved in metal stamping.
In metal stamping, a metal sheet is placed between a punch and a die and is then subjected to high pressure. The punch and die move relative to each other, and the guide bushings help to ensure that this movement is precise and controlled. The guide bushings are positioned on the die and punch plates to guide and stabilize the punch as it descends to deform the metal sheet.
Guide bushings are critical components of metal stamping dies, as they help to ensure that the stamped parts are produced with high accuracy and repeatability. Without guide bushings, the punch and die may move off-center or become misaligned, resulting in scrap parts, tool damage, and decreased production efficiency.
In summary, guide bushings are primarily used in metal stamping dies to guide and stabilize the punch and die as they move relative to each other during the stamping process, ensuring accurate and repeatable production of stamped parts.
Your bathroom exhaust fan motor has a brass bushing on the shaft for fan blade
@@1Esteband They do use lubricant, but it's added after installation and during periodic maintenance if the machine doesn't have a continuous oiling system. That's what the holes and grooves are for on that shorter one. Some brass and bronze bushings are impregnated with oil from the factory.

Американцы: wow, very cool, amazing!
Русские: не, ну прошлый век, открытая плавка, ручной труд. И это не подшипник, а втулка скольжения. В качестве замены смазки выступают графитовые вставки.
Корейцы: занюхивают стопку водки парами цинка и пашут смену дальше.
Только вот я не понял , почему в якобы "безмаслянном" подшипнике снаружи и внутри делаются характерные кольцевые канавки с отверстием? Причем отверстие очень важным, раз ОТК его проверяет. Канавки такого вида - обычное дело на вкладышах подшипников скольжения. Ну а графитовые вставки ( мое предположение) нужны для более мягкого начала движения вала и малых оборотов, пока не сформировался масляный клин.
Эти втулки для крайненизкооборотистых узлов! А канавка нужна для стопорения втулки.
В России до сих пор травятся при переплавке. Я 13 лет отработал на канальных печах и в этом видео мне понравилась горизонтальная отливка. У нас машины полунепрерывного вертикального литья с охлаждением кристализатора водой.
Сам процесс отливки очень древний. Литье с миксера в кристализатор через графитовую втулку под сажей или простые латуни под флюсом с октоборатом натрия/калия
Засоров в слитке на сложных сплавах просто тьма а сплавы типа СКА и ЖКС очень часто трещали да так что происходило полное разрушение слитка, и все это улетало в приямок литейной машины и то еще удовольствие было чистить эти прмямки. Так что корейцы молодцы. Работают на высокочастотках и передовая отливка
@@volnii_kot тогда зачем аналогичная канавка внутри втулки? Её видно на последних кадрах, где втулки упаковывают в коробки. Получаются, наружная и внутренняя канавки соединены отверстием. Это больше похоже на систему смазки.
Интересно. Сколько он стоит

Сначала взяли латунные трубы, расплавили, залили в форму, получили полнотелые балванки, потом снова нагрели, получили трубы прессованием, как я понял. Смысл этого всего в том чтобы в горячем состоянии, прессованием, получить латунные трубы? Т е структура металла другая?
Thank you from the video. Love Brass.👍👍👍
Well done . Informative 👍👍👍. Thank you for sharing. Be safe🇨🇦
excellent pipes, in which money has already been invested, to be melted down to make pipes again ..
This is cool!
Убило что корейская ОТК до сих пор не изобрела калибры)) Даже сортировка деталей на конвеере по типоразмерам идёт с помощью штангеля - долго и муторно.

'Their' attention to detail. It's 'their'. Pay attention to detail.
Great video - thanks for this
Amazing KOREA.
I saw one *GLARING* mistake. When the slugs were being oil impregnated, the operator immersed the rack of bearings into the oil at atmospheric pressure. When he withdrew them from a *drained* tank, that was when I realized that the company's 'institutional memory' was damaged. Items being oil impregnated should by put under vacuum *BEFORE* the impregnating oil is admitted into the vacuum vessel. Why? Because the head pressure of the oil is enough to cause the parts at the bottom of the vessel to be poorly impregnated with the oil, resin, wax, solvent, etc.
Many people won't understand the difference, those of us that do simply shake our heads in disbelief.
I think that's self lubricating graphite, though.
Hello kita hadir lagi nonton video👍
Very cool video..... I think I'll subscribe....
Brass is never used as a bearing . It is phosphor Bronze .
No heat treatment in video. In Russia using Cu + 1.2% Be. 1400 MPa.
I assume they were recycling material when the melt stage was shown. I would find it hard to believe that it would be cheaper to use pre machined stock in the foundry rather than just ingots. Also a nasty process with all that ash I would assume it's the lead burning out of it.
Yeah that N95 dust mask the guy is wearing wouldn't stop various nasty vapors.
Испаряется цинк
Это корейское ПТУ. Сначала плавят брак, потом делают брак и плавят, чтобы сделать брак и расплавить, но потихоньку учатся.
Нормально так, 0:35 безшовные латунные трубы надо изготовить что-бы потом их переплавить в подшипники????
Причём с виду новые. Возможно, какие-нибудь обрезки с соседнего производства.
Wonderful *Metal Fume Fever* is coming with all those zinc fumes.
The smaller diameter ones would make fantastic drinking vessels for a rich, slightly alcoholic engineer.
You can buy even larger ones for 15 bucks a pop, so it's not too expensive. Still, I wouldn't want to be drinking out of a cup with graphite inclusions (the black circles).
What are the slugs in the holes? Sintered graphite?
Good job wow...!
Brass bearings? This is the first time I've heard of them! Honestly I do not understand what it is and where they are used, The product looks more like a declarative vase or podstavka
@Milo Prager It's just a bushing for the bearing.
This is not its final form as I understand it?
@Milo Prager Thanks for the information I'm really interested to know what it is
So you learned something new!
And now something completely new: have you ever heard of Lignum Vitae bearings, or Railko bearings, or Cutless bearings?
They are used everywhere in manufacturing, linear guides and everyone greases them as well, that is why there was a cross bore.
I want some of those thick walled brass pipes they are melting.
Claims to be oil free.
Watches video.
There's oil.
"Oil-free", in this case, means they do not require re-oiling through their lifetime.
@@Evocatorum Please do not emasculate me in front of the youtube comments.
Похоже, с припуском делают. Доводить будут на других заводах.
Why are they melting perfect copper tubes, don't they have ingots? or is it some occasional waste material?
Waste.
Not copper!
Proprietary alloy is my guess
lack of proper material
I sat here and watched the entire video and I still don’t understand what they made. But they certainly made it quietly and well didn’t they
It's a bearing that typically does not require additional lubricant such as grease or flowing oil during operation. They are self-lubricating, and largely maintenance free from the factory. These particular ones aren't oil-FREE, they are just oil-LESS. Oil-free would be a dry bearing that only use graphite, PTFE (aka Teflon), or similar slick material.
The black plugs you saw them install are graphite. The material is often brass or bronze which is softer and slicker than the steel or chromed shafts they likely will support.
The oil dip you saw towards the end also impregnates the material when they drew down the vacuum. Think like a sponge absorbing water. That oil will slowly leak back out during use as the bearing wears, lubricating the friction areas.
@@MrEgdurd "like a sponge absorbing water" Thank you for your help. I understand it completely.
It's a brass and Teflon bushing not a bearing
It's that high pitch noise I hear constantly with my Tinnitus (ringing in ears).
What are they used for?
They would be pressed into a bore of some type heavy equipment most likely, and a shaft or pin would slide or rotate in the brass bearing bore. The dark plugs (graphite or lead maybe) would help as a lubricant, along with oil or grease.
They are bearing for mega machines. The idea is the spinning hardened steel part the size of a car, doesn't spin directly in the steel housing the size of a house, because when it inevitably wears from spinning both would have to be replaced to high cost, this is instead inserted into the hole as a "liner" aka bearing so this brass part wears out first from normal wear and tear and can be replaced.

I think that they really mean bronze not brass.
actually bronze is better but brass is pleasure to machine.
Вклеили на бакелитовый лак графитовые стержни, запекали в четыре этапа до 160°С и вакуумировали в масляной ванне. Так?
Ну и технология ;)
Подскажите а где применяются такие втулки?
@@user-gm9xg8xf5w линейные подшипники скольжения
Is the small inserts graphite? It seems that they are glued into the brass, though the liquid looks like oil.
Yes. And the bearing material is hardened bronze, not brass.
He mis measured the miromiter reading on the first view
Those plugs that go into the holes, how do they make it so they don't come out, if they go in so easy? and on top of that they even machine them flush with the od of the bearing. Am I missing something?
these are the real lubricants. Once the bearing gets hot, they slowly melt and come out. Very effective at low speed.
That's a brass bushing not a bearing
We use Bronze, much better.

Зачем плавить трубку если целесообразно плавить слиток!
Brass bushing = Oil free Bearing? ... grease lubrification for heavy load and slow rotation? ... have a good grease gun. Quality control measurement: go no go? = ...at go-go...and have fun.
Wow. There are MANY machining operations not shown here. Instead of boxing up the items they could have shown the machining and filling of the holes, or the shoulder on the bearings.
Also I didn't like seeing a laser engraver used on a polished surface with no laser eye protection for the operator.

Какие то отсталые технологии на уровне Пакистана: сначала хорошие трубы переплавили, затем отпилили циркуляркой, затем прогнали через пресс, опять отпилили... много отходов, нерационально всё
What is he measuring at 7:27 ? Definitely not the inner diameter. I think he is doing that the first time because a camera was there🤨, just a guess😂
Yeah I noticed that too. Yeah perhaps just wanted to get in on the video doing some measurements :)
well he is measuring the inner diameter for sure, not totally exact but good enough to see if its within spec for further milling.
Calipers can measure both external and internal diameters. Not with high precision, but good enough for that step in the process
It's quality control.
@@Happy357mag If they were smart they would measure the first and last piece, if they are good ,the chance of a difference between them is likely very small and wouldn't matter.. even if they would differ a little, they get machined after.. If they had such a problem with they tolerances from forming, they would make a bigger form..
So the guy measuring every piece was clearly just doing it because of the camera

Oil free ? They look like retainer housing for ball bearings
They ain't
You don't have a clue what you're looking at. These are oil-free aka self oiling bushings. Impregnated with oil so they don't require an external source of lubrication.

> oil-free bearings
> clearly contain oil
Yes you are correct, there is oil but not in the normal manner. The black material in the holes became impregnated by vacuum process @ 12:19
Graphite
oil-free refers to maintenance, not the presence. They don't require additional lubrication throughout their service life; one and done
Packaging was subpar but what ever.
Was frustrating to watch the whole process only to see the packing butchered
