Crankshaft Machining on a Nakamura WT-300

My LinkedIn: / denis-suvorov
"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

[@splob1981]

Same

[@christophercolumbus8944]

it's too confusing

[@paultyrer2171]

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

[@jamesdoughty1522]

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.

[@porkerthepig]

Same here

which nakamura tome ? what year?

[@craigm712]

Very nice process. I love the Nakamura Tome lathes and you are using them well.

the company i work for has 20 nakamura 11 axis machines, they have bar loaders and run 24/7 365 lights out. Amazing machines

[@mafosa8519]

[@shooter7a]

Lots of really cool stuff here. Smart tool paths. Steady rest on turret (!). Pulsed high pressure coolant while drilling.

[@Ds3DeniS3Ds]

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.

[@gunnathurdy8269]

Why not just use coolant through carbide, no peck needed.

[@currentbatches6205]

Nuts! I was looking forward to the machining processes on the rod journals.

[@maxbender8653]

Me too. But on a turret only machine there is no way for such an operation.

[@cromagnon305]

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 😊

[@StefanoLinguanotto]

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

[@Ds3DeniS3Ds]

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!

[@jonnis240]

@@Ds3DeniS3Ds never seen done this before. Really cool :)

[@MoistGrundle]

@@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.

[@CR3W1SH03S]

@@MoistGrundle There was the hole pattern on the end and the side milling cut which probably needed to be oriented.

[@braddavis4377]

I am a CNC machinist. I can't imagine setting offsets on that thing! Also imagine having to recut! Cool!

[@chrisyboy666]

Brad Davis why ??? It’s exactly the same as any other machine you work in XYZ just in different work offsets ??

[@braddavis4377]

@@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.

[@Welcometofacsistube]

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.

[@freshmas]

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.

[@Ed-zh5cg]

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.

[@TimSoKar]

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.

[@user-mv3ze1ck1k]

TimSoKar How did you make it

[@TimSoKar]

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.

[@ScoredPiston]

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.

[@fiteboss]

Lots of cast cranks in automobiles.

[@hamjudo]

@@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.
