It's beautiful and sophisticated equipment - but hats off to the thousands of machinists who used to make crankshafts on MANUAL mills.

I saw your comment that the part was run dry so the camera could capture the action but I am surprised the tools held up at all. I used to run all kinds of NC, CNC lathes and mills in the 70s and 80s. It would never have occured to us to try that. I ran parts on an electronic tracer mill that had tolerances of +0.0/-0.005 on a 6 inch span on a titanium part. Amazing what these machines can do. It's all in the setup.

aww man that first cut just sounds beautiful

The people who write the code for these CNC machines are legends now.

And just saying... Math ALWAYS works. Interpolation, Cartesian coordinates, Trig, Geometry. Math will NEVER lie.

Beautiful utilization of a TURN MILL Centre, great video and great work.

I love stuff like this thanks for the video. I was surprised at how much cutting they did dry.

Let me try to explain again a few things... First, this video is approximately 15 years old, and it shows how one of the earliest Mazak Integrex machines could make a crankshaft from solid material in a don-in-one process. Our customer here was a major (MAJOR) racing team who challenged us to make cranks from three different types of stock: (1) solid billet, (2) casting, and (3) forging. Each type of stock taught them, and us, something we were both looking to learn. This particular demo ran dry purposely so that the camera could "see" everything that was going on. Once we showed that the Integrex could make all of these various cuts, including the gun drill, we proved that we could produce just about any kind of crank from about any kind of material. This video's purpose is to open your mind and to allow your imagination run a bit wild.

be sure to turn your headphones up before playing

i love the way the shredds twirl around

The video resolution on is truly amazing.

Funny thing: I'm an Addy too. There are few of our family name in the US and those I've contacted descended from a few families who immigrated from England about 1880 to eventually settle in coal country in Wyoming and Utah where my dad was born 1911. Another funny thing: I'm a machinist too. I started my apprenticeship in 1961.

Hello Steve Addy, I can't wait to see your new videos with today technology.

The Precision is what facenates Me

One awesome piece of equipment ya got there my boy.....

Oh I love working on this machine :)

Great video and great share good work...Noel.

Amazing, I had now Idea how they made them, COOL!

I was a CNC tool grinder for ten years, and just made the switch to (Mazak) CNC Lathe. It's a big learning curve on the program language, and that type of machining.... for me. I was expert on the Okuma grinder.

very nice and good finishing

Thanks your share. Nice video

thanks...very nice work to make crank from solid metal...

that tool change is badass

Was this filmed with a crankshaft?

1:10 music to my ears

amazing technology

amazing!!!

Notice at 5:00 how the endmill creates a flat on an angle to prepare a flat entry surface for the forthcoming gundrill. 1000 psi is a very affordable option on the Mazak Integrex.

muy buen video de fabricación de un cigueñal felicitaciones por la oportunidad de compartir

yeah, that's the heart of an engine!

e la cima di tutto . bravi

É um trabalho muito bonito e bem feito.

good djob!!

Mazaks are some of the best machines I've ever run. 4 or 5 of them. The Integrex and Mazatrol controls are amazing the things they can control, and incredibly simply. Intuitively. Mori Seikis would be a somewhat distant second. Those Mazaks are a bad mother SHUT YO MOUTH!

Impressionante o trabalho dessa máquina muita tecnologia

im just getting into live tooling and i love it

Where I am going to work they have ten Integrex machines!

Real Nice

Most milling of steel and cast iron is recommended to run dry. I have seen massive improvements in tool life by just switching off the coolant. The reason for this is that the new TiAlN coatings like to run at higher temperatures and no thermal cracking occurs. The reason for the lubrication on the oil hole drill is to get the swarf out of the hole. On a drill this size, around 5mm, high pressure coolant of around 80 bar or MQL is recommended and definitely no pecking.

VERY GOOD SIMPLESMETE PERFECT

Me gusta mucho los videos saludos desde cuba l ❤❤

Intresting

That 1st cut sounds like some major electric guitar feedback. Reminds me of No Sleep Till Brooklyn by the Beastie Boys. LOL!

True this is a flat crank used in the Ferrari motors.

Chính xác đến từng chi tiết nhỏ nhất !

Nice 👌👌

SMART GRINDING

Steve, Thanks a lot for that video but obviously it wasn't really a NASCAR c/s because it was a 4-cylinder c/s machined in the video? And was AS 1045 the number of the steel, as opposed to 4340, etc.? After the crankshafts are roughed out in the CNC, do you guys finish grind them? I was surprised at that long drill with it's own coolant holes. That was trick! I loved the video; just wished there was more intricate info.

nice

They can also integrate surface hardening using a fiber-coupled Nd:YAG laser (a $20,000 option, mind you).

How does the indexable endmill compare to the traditional ones?

Reminds me of those science videos we used to watch in school back in the 80's. Except there's no guy wearing a sweater and telling lame jokes.

I don't know which noise is worse the tool cutting or drawing your finger nails down a chalk board.

IMPECABLE TRABAJO DE MECANIZADO .

thats a talented robot

The coolant depends upon what type of tooling is being used such as CBN,,Carbide,,or Steel

Epic

Turn mill its Good technology nice job

Công nghệ Việt nam bao giờ mới có nổi em này??? Mình mới có 1 em phay CNC 4th axis mà đã thấy quá hay và hiệu quả rồi.

Check out the one for third eye tactical scope mounts

vean esto, es de lo mas interesante.

StressPruf (1044) has been used for many years. 1045 is essentially the same.

damn pretty good quality to me what kinda calculator u talkin about brotha i want one!

just curious.. is billet steel forged and hot worked to increase strength like the videos showing the hot forge shaping of train axles.. how much stronger could it be... i recall an article where they are running fully counter weighted cranks in TopFuel classes as they spread the counter weights along the length of the shaft.. instead of just having the ends heavier to complete the balance.. stops the middle of the shaft from whipping

Anyone know the end cost of a crankshaft produced by this machine? That was amazing to watch.

Despite all the love for metal, you can use cooling emulsion for machining, because it hurts when you watch. But otherwise it's still a great achievement what old Mazak can do

harika bir tezgah

I cant recall any nascar teams using single plane cranks

A question just occurred to me ... State of the art computer controlled machines can spin the shaft and easily coordinate the movement of the cutter up & down to produce offset circular parts of the shafts (where the pistons connect). Old school machining (on a lathe) offset the shaft to produce the circular part of the shaft (where the pistons connect). The question is which technique produces more accuracy? I assume the tolerances achieved by todays computer controlled machines are better, (plus they are easier to setup). Your thoughts?

This is the same machine that milled the T-1000.

This is true but you can lessen or eliminate the chipping problem by adjusting the program to slow the feed at the start of yer secondary cuts. also a pause at the withdrawal point will lessen the tendency of the tool to grab a chip at the start of the second cut.

So was a whole magazine of tool bits killed cutting all this with no lub/coolant?

.....And off it goes to finish grind, for the grinders to make everything right

How long did this process take,from start to finish?

Haven't ever seen a V8 crank before have you home slice..All American V8s have 4 rod Journals..That is two rods to a journal for a total of 8..Damn kids, have to explain everything to ya..

Aluminum that leaves dark blue chips? Maybe the no coolant is so we can see what's going on?

Beautiful! Can you make me a billet LD28 crank. :)

Good luck having a crank made of 1045 bar stock hold up to the sustained high rpm a Nascar engine sees.

No coolant to let the work visible, but normaly they use oil in water emulsion to lubricate and cooling (indispensable to hold high precision)

Прикольно, конечно.. ))) Такой станок с 5-ю степенями свободы многое может... ))) Но на самом деле коленвалы на производстве просто отливают... ))) Это настолько проще, насколько и дешевле!.. ))) А побаловаться на станке с ЧПУ - это здорово!.. )))

I would assume no cutting fluid so the camera can see the cuts?

El futuro ya esta entre nosotros ,una sola maquina hace todos los procesos solicitados por el operador (CNC) ,en este caso un cigueñal ,muy buena maquina herramienta , la gente de RECTIMOTOSDINO COM AR

Where is the forging process?

Hog some material, great way to start a 7am shift.

this is like something out of robocop :D

Which CAM is here used for programing this operation?

They turned off the lubricant cooling so they would be able to film clearly. Notice how messy it got when they were drilling the long lubrication flow holes. I'd be surprised if that piece ended up anywhere but a display item or the scrap pile. I'd also guess that the bits that were doing most of the cutting got scrapped as well.

what was the point of those small drill holes?

In my humble opinion, if you can't see it clearly, it's not worth watching. However, I do appreciate the effort.

mi pasion

Higher resolution, please!

My question is: Why did they use 1045 mild carbon steel for a billet crank? Why not a 4140 or 4340 Chrome Moly Billet?

narly dude !

Is it a flat plane crank ?

How Many Axis' is that?? I ran One before, but not this newer Version. Itergrex 50 with T-Plus 32 controls.

I figured it would be 4340 as most of the internals in highend engines seem to be. \

I'm assuming it gets heat treatment of some kind?

can that machine make a replacement crank for any semi truck engine???

I guess we now know what tool chatter sound like.

Why would you WANT to use coolant while milling carbon steel?
