this factory belongs to a museum.
Wow amazing work
These guys are really skilled, OK this type of work is from a past era. They have the right work ethic and masses of skills. Very interesting.
Металл видно серый мало хрома.Чугун точно не подходит для коленвала.Напрасный труд.
Od co najmniej 30 lat dolewa się wały korbowe do samochodów tyle że jest to robione ze specjalnych gatunków żeliw sferoidalnych i modyfikowanych. Jeśli ta wytwórnia opanowała taką technologię odlewania to czapki z głów.

Amazing 001👍
Very nice work
If CAD and CNC machines ceased to exist in the west, we'd be hard pressed to find enough skilled labour that could do this kind of work anymore
Wonder what they used to mock up the cast.
one they got from the west.@@kensmechanicalaffair
Wooden pattern
What in the hell are you talking about..... how about you go learn a real skill other then keyboard wizard..... there are plenty of people that know this trade in the us
Интересно , из чего они это лепят , если вся обработка , практически "на сухую" и все как пластилин ..
i'm no crankshaft expert but i kind of think you should indicate with a dial indicator instead of a metal stick lol
Amazing work on primitive Victorian era lathes and machinery. These are talented machinists and mechanics but I'm sure there is a lot of room for improvement to bring it up to par with the rest of the world.
Yea, put this "amazing" shaft on your car

Yea, it's called a caliper......
The best place for the on/off switch on the lathe is definitely on the wall behind you.
Franchement, BRAVO ! Malgré le peu de moyens dont vous disposez, vous faites un travail remarquable.
Fantastic Job! All tolerances are guaranteed less than 2 fingers.
Oh my if it isn't another sidewalk supervisors.
Need to use a yard stick
I think that this factory is where Ford get their crankshafts for the 7.3 Godzilla gas engine. They are blowing up left and right at around 40 thousand miles. Lol.
@@gregorylyon1004 No, these crankshafts max spinning is 24 rpd (rounds per day). Never heard they made more than 2 miles.
Those are cast crankshaft. They don't usually last very long under high abuse. Almost all decent mordem vehicles use press forged crankshaft.
Well, there are cast cranks used still today, but they are Nodular iron (Sg) precision machined and induction heat treated to harden the bearing surfaces, but these are never used in diesel engines, only petrol engines.
Hi Vitor. Are you saying that these crankshafts come out of iron casting mold, but are not reheated and cooled rapidly which would harden them? How do you know these crankshafts are not reheated and cooled quickly? Do they look a certain way and you can tell from their appearance?
@@duckbizniz663 Hardening and forging are different things. Hardening only effects the surface of the part while forging effects the whole grain structure of the part significantly increasing its strength. I can tell it was casted by the surface roughness/pitting and the parting lines 1:06.
@@brianlove8413there are a lot of industrial Diesel crankshafts lasting ages. Some even not hardened at all.
@@danielsch8434 There is NO industrial diesel engines manufactured that have cast iron crankshaft, hardened or not. You will automotive petrol engines with nodular iron crankshafts, some are surfaced hardened, i.e. induction hardened at the journal. Good quality diesel engine crankshafts are nitride hardened. So, can you name any industrial diesel engines that have cast iron non hardened crankshafts? I know of medium speed diesel engine that do not have hardened crankshafts, but they are of an excellent quality forged alloy steel.
the main journal is always in perfect straight alignment😊
Yes, surprised that it already needed straightening! Relieving built in casting stress.
Kerja yang bagus mantap selamat beraktivitas
Mis felicitaciones a estos señores!! Gran actitud para el trabajo!!
Các bạn có công cụ và máy móc gia công thủ công cực kỳ chính xác và những tay thợ lành nghề, ít người có thể làm được như các bạn, ngoài các nhà máy sản xuất động cơ. Các bạn rất giỏi I like
70年代の日本の物作りに、何となく似ている気がします。インドだと思いますが、皆勤勉で真面目に働いています。
incredible skills!
Балансировку увидели, осталось увидеть измерение твердости шеек.
Да, балансировка, закалка, ну и стружки в каналах точно не осталось.
В мире много машин, где так де делают валы
Я тупо не пойму) Коленвал из чугуна что ли?
Highly skilled very hard working men, much respect
I can see Heath and Safety standards are a priority in this machine shop.
don't forget the safety sandals
It gives me goosebumps when I see people working with metal without protection, no self-preservation instinct. 😁
Then you have never been to a machine shop.... anywhere
I have to hand it to theses guys.. they got skills
สุดยอดมาก กว่าจะสำเร็จ ฝีมือจริงๆ
Salut super technique bravo Île de la Réunion
This guy is talented ! I love the way he eyeballs the crank into around .030" then uses a stick indicator to get even closer. All brazed tools and a perfect chip mean the best that 'OL machine can make! I'd love to see what he could do with my old XLO454.
Cast iron always has chip control ,you never machined cast iron
dude stopped all the laws of physics
25:53 so the same crank shaft is sold under at least three different brand names?
I wonder just how smooth these handmade cranks are. I am curious.
To me it looks like the material is too soft for a crankshaft. Forged steel would do better.
Cast iron is fine for general purpose crankshafts
Đấy là đối với bạn còn đối với công nghệ thì các kĩ sư, thậm trí cả chuyên gia người ta đã tính toán và sản xuất chúng ra ko phải là để mình phải bổ sung đâu bạn
*very cool) we don't do that)* 🔥🔥

I have seen some crankshaft manufacturing for 6-cylinder 3.5 liter engines. The crankshafts made here a much larger, for trucks not passenger vehicles. BMW crankshaft manufacturing seem to be more automated and there seems to be more quality control which are also automated. So where would this production method fall under in terms of durability and precision of specifications. Crankshaft has to work within an engine with other parts. So would this manual production be more accurate or less accurate?
Are you really comparing a multi billion dollar company that's got 100+ years experience to someone's backyard?
Mechanical Engineering is the fabrication and designing of metals. Auto-mobile Mechanics is the maintenance of motor vehicles.
These guys are cranking those things out!
Im a mechanical engineering student I watch this videos for my actual ojt shop
Hopefully in the “what not to do” class!
but still. the amount of skill these workers have is awesome
But what alloy, 😊what heat-treat, what surface finish, nitriding? Yes, talented and well intentioned resourceful guys. True.
Oh, what a great production of "high quality" parts
Where exactly there's a word of "high quality" other than in your comment? Why are you like that? You got to be fun at parties!
How did they make the first piece they started with?
HE'S GOOD LOOKING TOO BASED ON THE THUMBNAIL PHOTO !!
Could only survive in low shock applications like generators or automatic gearboxes with torque converters. Nowhere near a clutch. And surface hardening of random cast iron like this is a no-no...
see 20:11 I also want some safety shoes like that .. where does the company buy them .. they don't supply the same model to everyone ??
One word: Wow!
Это же чугун😱😎 Как можно такие ответственные детали как коленчатый вал делать из чугунного литья. Я думаю это опасно.
Почти все жиговские колена чугунные
@@viktormanko19 Удивляюсь!
Are they suppliers for factory or for aftermarket sparepart....?
Taki wał i technologia to może być dla śilników 2 tlokowych czy max 3 tłokowych. Zasada jest jedna jeśli ktoś kupi taki wał to w naszym kraju musi iść ponownie na osiowanie, wywarzanie i szlif !!! Obowiązkowo !!!. I z nominału robi się już 1 szlif przy wale nowym jeszcze nie zamontowanym. A i tak bałbym się zkładać bo to jest plastelina. Jak by spadł z małej wysokośći to by odkształcił by się. Ciekawe jakie różnice są na wysokośći korbowodów, i chyba nie mówimy o x,00 a raczej x,0 . Bo tutaj jak w chinach byle się kręciło. A wał jak pochodzi 2 lata to max. Czy mi się tylko zdawało ale tam chyba ani razu nie użyto mikrometra !!!. Te wały są do śilników gdzie są starej daty. Bardzo mało koni ,nie wysilone lub i pracujące jednostajnie na wysokich obrotach. Bo do ciągnika strach to założyć. Jak Czop główny tylko środkowy jest sprawdzany. Nawet nie przykręćili do bloku testowego i nie pokazali jak się kręći
Fastest caliber readers on earth 😂
No cad CNC auto feed a real talented expert
Good to see the workers wearing OSHA approved sandals!
Health and safety took the day off.
what the hell are they doing with those lathes ..where is the gearbox ,, have they peeled it out and put it in a truck =+
О точности металлообработки, особенно при сверлении, говорить не приходиться. Вряд ли у этих деталей большой срок службы.
I can't imagine how many of these mechanical lathes GM and Ford would have had before the CNC.
i, too, enjoy polishing my crank
Good work
Inheritance machining would for sure cry if he saw this.
Me gusta estos trabajos
It is the most important part of the car or machine
Arriving at a Caterpillar factory soon!
4 jaw chuck and he never zero'ed out a single surface. Just adjusted it with a hammer and away he goes. I wouldn't ever pay money for one of those cranks, even if I was only going to use it as a boat anchor.
This is the reality of the process for finishing a rough forged crankshaft these days. There was a time when General Motors offered an unfinished crankshaft and a machinist would spend up to 2 days getting the counter weights and journals cut concentric to one another. At some point in this video they will actually put the piece on a crankshaft grinding lathe to finish it to original specifications
Н - надёжность 😆, Т - точность 😂, У - уверенность 😜
Н - никогда не ездит на этом самому!😂
29:25 I like how the thing is balanced by hand
Is a joke
it probably spins at 2k rpm max so doesn't matter lol. An if it breaks it cost 50 dollars a new one and 20 to replace.
And no Bob weights
It is a very clean well organised shop with purpose made equipment in good condition - far better than what we normally see.
YES t yes but there is still a long way to go .. security does not exist
What country do you live in?
I love these ironic comments
Да уж, почему не напильником шейки коленвала шлифовать ещё не начали))) Кошмарный сон Японского инженера )))
Снял с языка. Хотел об этом паписать.
Until the crankshaft was transferred to the grinding machine, I thought it was a pre-machining and the work would be finished with the CNC machine, then the grinding would be done.
A sneak preview of what the engine will actually sound like 😅
電動車馬達 取代 油車引擎 AI 自動化 取代 人力 之下 這技術 顯得 珍貴
how much weight of these crankshafts?
the most hilarious part is the balancing of the crankshaft . all tolerances are in 2 fingers spec.
nice work for caren sheft
Soll das alles so trocken bearbeitet werden?
A cast steel for a crankshaft??????????????Amazing butchery!!!!!
Kills me the way they do all the machining and just throw it on the floor
its "Drop Forging".....hahahahah
@@10OZDuster 😂😂
Long sleeves and loose clothing: check No hearing protection: check No eye protection: check Only thing missing is children and a people wearing sandals
As long as you will not operate it in low revs ,high load,it will be fine
Sub contractors for Ford no doubt.
OSHA would lose their minds walking through that shop.
Original part quality
HAHAHAHAHAHAHAHAHAHA
Hierro fundido para un cigüeñal?, y eso que vida tiene?
Arbore din fonta?
It's funny how every one of these videos is sped up, yet they all look like normal people working.
Open toed sandals are a great Health and Safety restriction
Thời nay làm cũng ăn, nhưng ăn luôn từ đầu nói toẹt ra là ăn bớt để hạ giá thành còn cạnh tranh.
На 0,30 в чем смысл имитации балансировки вала????? А вращающийся центр не судьба использовать? И как долго эти коленвалы ходят?
в следующей серии это переломанное колено привозят на сварку ))))
Вы супер!!!
Is he eyeballing those cross-drillings???
Дааа милионник готов!
Окупает ли данный коленвал затраченную на него электроэнергию???
Полагаю у них ситуация -за не имением прачки любим дворника!
Considering the equipment and time given to them the 4 people on the lathes and the old fella doing the balancing did pretty well. Ive yet to see a torque wrench or new oil used on an engine rebuild in Pakistan, they just use smaller or bigger people to tighten bolts down to spec lol It's probably the same people that make the bearings so its all good lol
OLÁ. Vos informo que a mais de 50 anos passados já existia "balanceamento ESTÁTICO e DINÂMICO" . VOSSO sistema e sequencia de usinagem por vezes está invertido. Desempenar o eixo já acabado na prensa somente se for no mês de Maio. (UMA BAITA "MAITAÇÃO"). ABRAÇOS Roberto Udo Krapf
Trabalho muito bonito. Quantas horas de serviço tem para usinar uma peça destas. Estão de parabéns. Tem minha admiração.
Pues pocas ,porque es de fundición gris, cuando los cigüeñales se hacen de acero forjado.
If you want avoid fatal engine damage, never use pako-tec components! Here the correct use is only for pedestals for mailboxes and flower vases.
Are those crankshafts made of cast-iron?
Yep
@Will he heck as like Ductile cast iron is a very commonly used material for crankshafts, not just in India, everywhere. Most OEM crankshafts in general purpose engines are ductile cast iron with cast steel and forged steels being used only for higher performance engines.
@@willheheckaslike8315всегда можно просто сделать коленвал толще)
@@mattsta1964this small factory is located in Pakistan not in India.
That's some precision work
