I remember on 1975 on my tool and die maker school the teacher making a crankshaft, that was the most difficult machining to be made without cnc process leathe, micrometers, depth gauge, a true knowledge of what the past was, ... very proud of my teacher....👽👍
Very interesting process to watch. I'm surprised that the only time coolant is needed is when drilling the oil holes. I'm a retired Master Engine Machinist and over the years have ground hundreds and maybe even thousands of crankshafts. Fun job but they didn't pay us enough.
@Felony Videos Obviously never heard of an AdBlocker addon? What commercials? You're watching a free video, so you get what you pay for otherwise... ;)
On the first crankshaft, what is the percentage of waste material after the machining was done out of the stock? Any idea what size it was at beginning to get a sense of scale of this item. Really enjoyed this one... no ads ;)
Way too many commercials!! C'mon, I know everybody wants to get paid but seriously let's not forget that the whole concept is to enjoy the content, and not be compelled to yell at it every couple minutes cuz it cuts to a shiddy commercial! Fk.
سلام من وقتی این دستگاهها رو میبینم غصه میخورم که چرا ما نداریم این تکنولوژی ها رو با این که ما با یه مشت دستگاه قراضه داریم کار همون رو انجام میدم ولی حیف
I don't think that the crank shaft they made here is for any real use. I think it was more of a demo part. The size of the part compared to the chuck makes the crank really tiny.
Billet crankshaft made from a single piece of quality steel as opposed to the second cast crankshaft.... it's a strength thing...the second would break or fail under heavy load .....the first for performance...
Well no... if you’re roughing it’s better to use air as coolant, since you don’t have Thermal shocks at your cutting edge... for finishing you should still use coolant to make the surface better... the best option for tool life is no coolant, except for drills, they need it. Just make sure with your cutting parameters that the heat will go in the chips, not your part
The theory is the steel chips take the heat away from the tips, with the correct speeds and feeds the actual carbide tips should not get over hot and they do not burn out like high speed tool bits
Perhaps if you stop to to realize yes being able to make one is cool. However, a crank shaft produced from a forging doesnt waste half of the stock to make it and is actually stronger.
@@oceannavagator Most of the engineers I have had the pleasure of working with are very hung up with the "title" of engineer and often feel threatened by anyone that can understand things that give them trouble. They dont laugh they quiver in fear of being laughed atso you just have to make them think they are coming up with all the ideas. Some are pretty knowledgable people but by and large many of them still dont always understand that having the title of engineer doesn't always make them right about everything. If I wanted a one off crankshaft and could not obtain a forging I would be happy with one made from a billet of the right steel.
Excellent machining. But I wonder who’s ready to pay for such a piece of amazing work ? It’s only reserved to very special car such as rally or formula. Otherwise, cannot be used in mass production, too expensive ! Time required and loss of material (steel of high grade).
@Alain Mare. Your right, but they're pretty popular. with dragracers as well. ]They will often choose a billet over a forged unit. The Big Block Chevy V8 billet cranks are around 4000 USA retail, While a forged BBC crank is around 2500 retail. The popular Toyota 2JZ inline 6 cylinder crankshaft can be had in billet for 2300 USA retail. The popular K series Honda engine billet crank 1900 USA So they're really not that expensive. Of course, a custom one-off can be expensive.

Again a good clip wasted by stupid and annoying music! Why don´t you let the machines and materials speak for themselves? Squeech, scratch, boing, fizz, fuzz etc. That´s "musique concrete" at its best!

Yeah..marking out and centerdrilling the holes so that the cranks can be manually turned between centres lol...remember those days too...

This's video is amazing
I am learning a lot.
Thank❗️
Thanks for the good machining with prescision we need more!

They probably did it for filming purposes. I worked in a shop with a crank grinder, and yeah they didn't charge much for the job idk why
I have never seen this many ads in one 20 min video.
I didn't See any ads. Chance your yt App.
There were 11 ads for me, I stopped watching after the second ad.

Do you still have the original source video? I'd like to see the not-sped-up version, even if it is hours long.
Космический коленвал , нет слов , цельно точенный !!!
Can we get some info on the part? What kind of engine will it be going in?
Being a Diploma holdee i never see such accurate working.Thank you so much...
H::
Pls how do i apply for apprientiship .
Please tell me name of this machine?
the good machining with prescision good accuracy
Столько металла в стружку должен быть очень дорогой коленвал. Обычро литьем получают с дообработаой.
So crankshafts are usally cnc- milled ? And then to desired specs? .
That machine is amazing. Programming has to be extremely accurate. Everything must be timed perfectly or bad things happen.
It can be simulated at the computer before running.
@@daobinxie4570 Imagine programming something like this with punch cards
@@raivis2973 Hard to imagine how much work will be.
Pins are always ground in, their left oversize on purpose. extremely accurate? Naaaaaa!
We produce hundreds of precision cranks a day, this ain't shiiiiittttt
nice!
i am soo happy this video good learning and helpful also tq u soo much bro i love it
ধন্যবাদ...
thanks

Im curious about stress in the material when crankshaft made this way
Can i know which waterial using crank..

👌👌👌👌👌
I cringe when I see the sparks I get PTSD of my dad smacking me upside the head for not using coolant
That first cranks was an absolute waste of material. You could have made 2 more out of the wasted material.
I don't think that the crank shaft they made here is for any real use. I think it was more of a demo part. The size of the part compared to the chuck makes the crank really tiny.
Ever made crank from Billet to judge?
Billet crankshaft made from a single piece of quality steel as opposed to the second cast crankshaft.... it's a strength thing...the second would break or fail under heavy load .....the first for performance...
@@indigrace6584 forged crankshaft is best
@@psk5746 I thought all billets are made from a forged piece?
Dumb question: why is so little cooling fluid used? Wouldn't it make the tools last longer?
Well no... if you’re roughing it’s better to use air as coolant, since you don’t have Thermal shocks at your cutting edge... for finishing you should still use coolant to make the surface better... the best option for tool life is no coolant, except for drills, they need it.

The cutting head has diamond?
Yeah... diamond to manufacture steel parts... definitely a great idea 🤦🏻♂️

You'll have to tell formula one engineers then.
@@oceannavagator I have been telling engineers lots of stuff for many years the only way to get them to listen is to make them think its thier idea.
@@ALSomthin I'm sure they have a nice laugh over it.

Worked in a forge for 20 yrs did cranks, cams, rods, pinion gears, ring gears etc. all for GM.
@10:45 the machine synchronized with the music drums/beats
凄か〜、材料費高かね〜。

Full of ads.
Why not start with a smaller diameter round bar? All that time wasted machining so much away
i like to eat ice cream
Less expansive forging for small car crank shaft

Что только не придумают для обработки коленвала. Первый вариант очень затратный.
