"A good cycle has to be engaging to watch and to never be boring. A well thought cycle sounds like a masterfully played violin"
The turning stage of the manufacturing of a crankshaft on the Nakamura WT-300, realised by collaboration of Denis Suvorov and Marco Fiorido, Product Manager for Nakamura.
As a machinist and a diehard car guy, this was satisfying
Same
it's too confusing
It's cool to see some of the stuff these machines are capable of. We use similar machines where I work, but we don't use them to half their potential.
Same here
which nakamura tome ? what year?
The people who design these machines are the true engineers ,I ran manual lathes ,Mills, and grinders till I retired last year could never get to grips with programming cnc stuff , most of the chaps who operated cnc machines couldn't use a manual machine either
the company i work for has 20 nakamura 11 axis machines, they have bar loaders and run 24/7 365 lights out. Amazing machines
That was waaay cool!
Lot of “set up time!”
Larry
Yeah, a lot of initial fine tuning but once everything was set it was actually pretty fast to set up for different crankshaft models.
Wow! the coolant drips up. Now that is a real piece of technology, har! Great vid!!
Yup. I didn't notice that the camera was upside down until close to the end of the video.
Lol didn't even notice. I was concentrating on everything else. Nice catch.
Thanks for sharing your proces under dryrun! Really! I love ppl that can use a Machine to its full potential!
"What exactly are your plans for my daughter?"
Me: 3:08
Jesus 😂😂
Lol
Lots of really cool stuff here. Smart tool paths. Steady rest on turret (!). Pulsed high pressure coolant while drilling.
Thank you very much for the appreciation, a lot of work was put to optimize the cycle! The pulsed high pressure coolant was just for video, but the turning can actually be performed without coolant with this material.
Why not just use coolant through carbide, no peck needed.
Very nice process. I love the Nakamura Tome lathes and you are using them well.
Now i know what i want for Christmas
A ps5?
Makes me miss my Nakamura-Tome selling days 30 years ago. Good company.
Magnificent machines... very swift tool indexing and high precision machining...
Wouldn't like to single block that program through for proving out😂
You’ve found your programmer on a great CNC lathe.
Wonderful chucks!
Thank you for know music! Let the metal do the singing! My wife thinks I’m scraping my fingernail on a chalk board,, it’s great 😊
A FAAAARRRR cry from those old Sterling gear drive lathes in High school.
They where 25 yrs old in 1990.
Fantastic job
I can imagine the programmer and the set-up person fighting a few times before they finally got this dialed in.
imagine the crash tho
Been there, Done that.
Beautiful cutting.
2:27 that was pretty amazing
this idea comes from a sick mind
Cudos to the person who programmed this operation. that must have taken WEEKS!
And tons of wasted stock

Nakamura .............................................
Cool AF
I am a CNC machinist. I can't imagine setting offsets on that thing! Also imagine having to recut! Cool!
Brad Davis why ??? It’s exactly the same as any other machine you work in XYZ just in different work offsets ??
@@chrisyboy666 yes cuz but also the other axis as well, not to mention that the workpiece needs to be trammed to each axis and this like at least 5 axis. I have only been doing CNC for 6 months so I have much to learn.
Brad Davis I’ve been doing it for 17 years and I have much to learn.
Best thing about this profession is you never stop learning.
Brad Davis lathes like this are not as bad as you think at first, not to diminish the work involved or the cool process. I’ve never ran a Nakamura, but on a Mazak you’d just program two 4-axis lathes and add wait codes so one turret doesn’t move past whatever point until the other turret has caught up. If you put two wait codes in a row, it guarantees only one turret operates at a time. When you’re proving out a new program, you have a switch to make it so you can start and stop the turrets individually.
Looks like the work offset was set by the probe in Z and the rotation in Z at the beginning of the program. The tools I'm sure where set by a tool setter. All programmed so operators not machinists can run it.
they hit me in the eyes i can feel them
Very nice
Yeah, that's cool
That is some aggressive machining
Well work
TIL crankshaft can only be machined with anti-gravity coolant that falls up
Really cool 👍
It’s very interesting to see how other brands make their parts. I work in a place that makes crankshaft for Nissan, Mercedes, Renault... and it’s definitely not the way they are made.
TimSoKar How did you make it
Lots of different machines. Each machines are processing just one step of the machining cycle. The steps are not in the exact same order too.
So, one crankshaft is made every minutes but it takes nearly 30 minutes for a crankshaft to be made.
Based on the fact it’s a cast crank I wouldn’t think this is for a car. It’s a 2 or 3 cylinder by the look of the journals. Maybe industrial equipment or small diesel crankshaft. So that’s why the tolerances are probably less and the machining is faster.
Lots of cast cranks in automobiles.
Well that sounds very well indeed!
Is the tool at 0:25 just a mechanical stop to force the crankshaft in position? Or does it act like a probe and the machine adjust the C axis position from the program?
Thank you in advance,
Stefano
Thank you. Nakamura has a feature called Navigator, so as you said it basically acts like a probe, but with physical contact. You measure the torque of the motors, in this case the C-axis, so when you make contact you record the C-axis position as you pointed out. Same concept for Z-orientation!
@@Ds3DeniS3Ds never seen done this before. Really cool :)
@@jonnis240 I have to agree, its definitely an interesting way of locating. Whats more interesting is it probed the rod journals, but never machined anything eccentric. Just a bunch of interrupted concentric cuts.
@@MoistGrundle There was the hole pattern on the end and the side milling cut which probably needed to be oriented.
This is a real making money machine
or if one of the tolerances is out, a money wasting machine =D
Nice work
That's a badass machine. Kinda makes the mazak hyperquadrex I run look out dated.
Aaron Henderson lol try the Haas crap I work with.
It kind of threw me off for a second before I noticed the video is upside down.
@@Welcometofacsistube I started off on a couple haas st10's straight up 2 axis extremely basic machines, no tail stock no live tooling no insert tooling. Best thing I ever did was get the hell out of that shop and please keep in mind that I'm only 3 years deep into this trade
عملك رائع واتمني لك التوفيق
Awesome! But I would have programed it to wipe camera lens too.
or at least an air blast to clear the debris- lol
i want to see part 2
I'd like to see the next operation on this part
th-cam.com/video/wScM0J05H0A/w-d-xo.html here it is. Although there is an intermediate step in which the rod bearing journals get machined.
I knew Hikaru was a robot!
All clearance is good clearence.
Great video! What steady rest are you using here?
Crank shafts are cast that explains everything
I keep thinking im going to get metal fileings in my eyes 👀
me on a YT recommendation spree: oh it's cnc porn time
the cnc machine: 3:06
Oh well...
0:50 what was that
What?
@@lehonwhale8070 Что?
03:12 after the no nut november
underrated
my girlfriend: wait me honey
me: @3:24
Made in japan?
Да хороший станок вот бы мне такой тогда бы я нормально зарабатывал на себя но увы 20.000.000 руб нету у меня((((
Why’s there no lube/coolant shooting on the bit?
We require this type machine for shaft turning give me help
Beleza.
who is producer of steady rest? I see thtat top is SMW, but who assembled this?
Everything is so simplified nowadays. In my day I used to machine crankshafts with a normal lathe. Today, it means no jobs.
Я правильно понял, что это токарный станок, который выпиливает коленвал ?

Video is upside down
Good
👍👍👍👍
I Demand to know the name of this company

*terran theme plays*
Is the A turret support coolant or live tool actuated
Manteeeep
两分零五秒的时候，震刀了呀
А где охлаждайка?
No coolant?
Mainly for the video, although it's not too critical to use coolant to perform turning of spheroidal graphite iron in comparison to other materials.
Carbide.
Охуенно!
CNC????
No...it was all being done manually...couldn't you hear the guy winding the handles? SMH
@@Penguin_of_DeathIs there an orchestra conductor that reads the G-code and keeps everyone synchronized?
There were at least two guys winding the handles. The synchronization was amazing when they were moving both tool holders at the same time. With all of the stuff going on, I am guessing that there may have been a third operator controlling the coolant flow and the tool changer.
Clockwork precision. Truly amazing.
@@Penguin_of_Death lol
3:09 First time huh..?
Всю камеру обкончали😂
😳😳😳😳😳😳
Video was going good until it got squirted on. And not the good kind of squirted on either. Lmao
3:25 so that's why she always complains!
3:24 😂
3:11 O____o
Slovakia cnc program😉
撮影のためにドライ加工？
По-моему нужно маслом обрабатывать
The machine is incapable of doing the mains and throws.
Seems kinda useless.
