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
Don't bother. If you show this to a west mecanic teacher, he will have a heart attacq. And he will need just 2 months to form better machinists with higher standards!
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.
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.
@@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.

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.
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.
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
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?
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
They way they lifted that crankshaft, a kid and an old man, tells me how light weight that is, they have no clue on metallurgy, so much labour but not meant to last.
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...
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
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

The best place for the on/off switch on the lathe is definitely on the wall behind you.
this factory belongs to a museum.
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.

@@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.

Highly skilled very hard working men, much respect
Amazing 001👍
the main journal is always in perfect straight alignment😊
Yes, surprised that it already needed straightening! Relieving built in casting stress.
but still. the amount of skill these workers have is awesome
incredible skills!

Cast iron always has chip control ,you never machined cast iron
dude stopped all the laws of physics
*very cool) we don't do that)* 🔥🔥

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

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 ??
Балансировку увидели, осталось увидеть измерение твердости шеек.

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.
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
Good to see the workers wearing OSHA approved sandals!
Health and safety took the day off.

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.
As long as you will not operate it in low revs ,high load,it will be fine
Are they suppliers for factory or for aftermarket sparepart....?
Realy good like old german Manufakturing style
О точности металлообработки, особенно при сверлении, говорить не приходиться. Вряд ли у этих деталей большой срок службы.
