Mazak Integrex Machining NASCAR Crankshaft from Solid - Addy Machinery 

This video was intriguing to me. I am a mechanical engineering student, I work for a big name motorcycle engine manufacturer. I desperately want a lathe and mill of my own. Even crappy ones would do!

You guys sell my employer machines. I'm curious why a machine similar to this wasn't sold to us for our crankshaft machining processes.

Also, do the journals on the crankshaft need to be polished post machining or is the surface finish good enough for immediate installation?

Fppp

what about the chamfering part ? or is that chamfering which operation is that and do you recall how you modied your turning holder or boring bar?

What are you even trying to say? Are you trying to feel smart by throwing around words from High School?

​ @Distropital Be nice nice man. Just because you're on the internet doesn't mean you have to be a "richard" I've forgotten more college math than most people ever heard of. Math ALWAYS works. There's always 3 or 4 different ways to prove out a theory. COMPLETELY different ways and they all come to the exact same conclusion.

and replaced with master cam lol

haha, this is true.

This by no means is an easy accomplishment even with mastercam.

koolbeenzbro My old boss did not like doing holes. Drilling the oil hole on a angle like that must have been tough to get right

Boerje69 - it was filmed with a potato sitting on a crankshaft lol

this beat kinda hit, damn

Rất nhiều người trong đó có tôi đã từng rơi vào trạng thái : nhiều lúc muốn làm nhưng lại thấy không được làm, nhiều cái được làm nhưng lại không làm được. Ở đời, "làm được" và "được làm" là 2 thái cực khác nhau. Ai đó đã thành công thì chắc hẳn phải là người kết hợp được hài hòa 2 thái cực đó!

hey joe are you a mazak operator? which software do you work with is your Integrex 640MT fusion also?

Working where I work might make you change your mind. We make palletizers for the canning and bottling plants and we have plenty of complaining and politics. This company claims to be "people-centric". It's just a way of saying they are going to involve themselves in every aspect of our personal lives whether we like it or not. The jury is still out on the legality of this.

Sorry, couldn't help but laugh. But that's actually a pretty serious injustice. I can't count the number of times I've heard "people centric"--just another political football. Usually comes with lots of lawyerly small-print your micro-managing employer fails to show you. I'll spend the rest of my life trying to keep away from that, if I can.

***** first time I've heard of this. crazy stuff. so glad i don't work in big business any longer.

***** Funny, how my comment got me less responses about engineering and more about the greed and chauvinism of today’s employers. And though I still don’t think anybody wants to switch over to traditional Marxism, you can’t help thinking this was never such a widespread issue in our country. At least not through most of the 20th century. You used to be able to go to your job, get paid a living wage (here in the Mid-Atlantic that’s a little more than $20/hour), and you were known mostly through your participation in “community organizations”-church, AA, Moose Lodge, spiritualist group, self-improvement group-whatever. But it wasn’t this case where your employer pays you squat, then keeps tabs of your personal life as though you were a specimen in a jar. But we also didn’t used to have a “permanent war economy”-or a permanent war mindset. WWI was our first overseas war, one which proved immensely profitable for everyone besides the men who fought it and the civilians they bombed. Unfortunately, it seems the men who profited were in a position to start buying up our news media-which they then did (AP is largely under the duress/oversight of Reuters, and has been since...sometime around WWI). And so, a few short years later, instead of still hearing horror stories from WWI vets, these were replaced with calls for yet another expedition to Europe. Then one to Korea, and another to Vietnam. In the process, we “fought” the cold war-a state of constant readiness (along w/ constant expenditures on lots & lots of bombs). Then, cold war over, suddenly in the mid-1990’s we’re bombing Osama bin Laden in the middle of a desolate region nobody knows about (except for it being the world’s supplier of opium-if not also a highly strategic area for both possible oil pipelines, as well as for launching still more wars against oil-rich nations). So, my point is we no focus on anything within our own camp. Instead, there is now this ever-constant “unseen foe” lurking...somewhere...and it’s supposedly our sworn duty to go off and fight him. And so nobody gives a damn about American community-“It’s a Wonderful Life” has gone from being a chronicle of American existence to a very long-ago and distant dream. And I know I’m oversimplifying a lot, glossing over a lot, but I think if you get down to the primary essence of what’s wrong, that wrong lies in the fact that in the early part of the 20th century we ceased having leaders who cared so much about America and began having leaders who cared mostly about war profiteering. Everything else-the private central banking system, the lobbying of congress, the erosion of our cultural mores, porous border policies, dumbing down of all our institutions-if these didn’t specifically grow out of a new policy of “imperialism”, then they were made possible by it. And I’m not a pacifist-but that’s also not what I’m talking about. I wholly believe in fighting a war of defense. But that’s not what I’m seeing. Instead, I’m seeing a constant, never-ending “us versus them” politic, with the actual immediate threat of the “them” never being fully proven, always kept semi-shadowy, and the actual spoils of the consequential war never getting evenly divided to the “us”, but rather, only to our leaders and corporate leaders. And that’s not democracy. That’s empire. And we’re not set-up as a nation to be an empire-you look at our constitution and that’s quite specifically for a democratically-elected republic that is constantly monitored by the public. But...I’m not in a position to do much right now. I have legal problems of my own, money problems of my own. But I am making a mental folder of all that I see, and what I see is an American people which doesn’t want to be made an empire compelled to be made into one. Americans seem to be compelled to these ends through “economics of scarcity”-however, the thing I notice most often about scarcities is they are artificially created. And that is what I, myself, would war against. This, just for the sake of eventually living in a community that resembles “Bedford Falls”, rather than always having to live in a place that resembles “Pottersville”. In Pottersville, everyone is exploited and all the better resources are grabbed by the slumlord; the people follow his example and grab all they can for themselves. In Bedford Falls, the leadership is more just and altruistic, and the people follow suit.

***** Beyond all that, I always found Perry Bible Fellowship cartoons help (although they have nothing to do with any Bible fellowship--I don't even know why they were given that name): comicsidontunderstand.com/wordpress/wp-content/uploads/2011/06/shrink.png

¿SABES DE MECANICA?

Agreed. NASCAR doesn't use 180 degree cranks. The internet is full of misinformation.

The T-1000 is a "memetic poly alloy", thus not requiring machining. The T-600 and T-800 maybe. But in all honestly, Turn mills aren't great for large complex profiled parts, better for rotating components.

I have been corrected... I feel soo humble now I didnt even know that fact. :)

@@Dave-vu4sx Hey Dave. I have not worked as a machinist since the 80s. What is memetic poly alloy and the T-1000?

@@wernerdanler2742 ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Fa4Jq7gJvZ0.html - This should answer all your questions, in the 80's we only had T-800's, but around 1991 we had the T-1000. :)

yeah, i noticed when the video started back up it's the first thing they show...i ran an intergrex mazak but it was just 3 axis

Two rods per journal.

And, if its a V8 then it would be a flat plane crank so you're absolutely correct! Thing that puzzles me though, if it is a V8, then why is there only one oil hole on each throw journal?? Might be because they use a single V shaped connecting rod (I doubt), or a master and slave rod, or conventional setup where both rods overlap the oil hole , or ever a fork and blade design. I'm puzzled.

ThePaulv12 because it is, in fact, a four cylinder crank! I noticed they use a 0.984" end mill to machine the rod journals, which is SBC sized rod bearing width. That explains the single oil hole per journal. Is a four cylinder crank still illegal in nascar? ;)

+Chris Stavro Thanks for that confirmation. I paused the video, counted the journals and couldn't make sense of it.

But I wonder what is the stroke & bore it?

hey Mike are you a mazak operator? which software do you like with the Integrex is it for 640MT?

+DivineBetrayal The heat treat is done after the cutting is complete.

I think they didn't use lube this time otherwise we wouldn't be able to see the process clearly

U can roll without coolant on roughing and finishing

But as u can see on the drill with the thru coolant...they were using coolant..so it was probably shut off for demo purposes

TheNative7th coolant is needed for that kind of drilling. to cool the tool in such a deep hole and to flush the chips out.

tomte47 I think they just turned it off for that run and slowed down the machine to give the camera a neat view.

probable more to clear chips then for heat management

Brainmalfuction That exaclty what I meant; peck drilling is just TO clear chips.
