I can't be the only person who find the rough turning segment to be so satisfying to watch...

[@Been.Here.Since.2007]

The unevenness of the metal is crazy

[@balooc2]

i love that you have a smaller chuck in the larger chuck, instead of changing chucks ^^

[@grumpyg9350]

Awesome looking piece. Machining at its finest Chris! Nothing like seeing what lurks inside that ugly raw piece of steel! I miss making those hot corn chips but didn't like getting hit by them.

[@IanTheWoodchuck]

I know I'm seeing this WAY after the fact, but I was just recommended your channel because of my love of industrial machining vids. That said, That is the BIGGEST damn "micro"meter I have EVER seen! NICE TOY!

Hi Cheis

[@NeoHack]

Great work.

Goodway CNC , Amazing !

[@a-fl-man640]

that must have cost a fortune to machine. that CNC lathe is a monster. what a massive chuck. nice work

[@douro20]

This is still small for a vertical turning center. This can also do 4-axis milling.

[@andreweppink4498]

Can't believe the part wasn' forged closer to final shape oven if it is an open die forging. Much stronger part. Much less waste. Can't believe all that was in there, surface finish and all, before the machinist uncovered it.

[@MekazaBitrusty]

I was thinking the same thing. There was way more weight in shavings than the finished product 😮

[@Gin-toki]

I was thinking the same but then again, if its not a mass produced part, it might be the customer does not care about the extra cost of longer machining time. And perhaps the extra machining time is less expensive than a more elaborate forging process.

[@b2dmastersniper]

Damn, thats the biggest live center ive ever seen

Very impressive, I’ve never seen a Chuck mounted in a Chuck before.

[@ChrisMaj]

Some people don't really like that idea, but it saves me a lot of time.

[@jimhimesjr]

@@ChrisMaj I see no issues in a manual lathe. Have done the same. In a CNC however it can be bad. I saw a guy almost loose his hand cause he forgot and hit the pedal to take the part out and the whole 15” 3 jaw chuck fell on his hand. His hand was crushed pretty bad.

[@ChrisMaj]

@Jim Himes I don't have that problem. None of my chucks are hydraulic.

[@piter_sk]

@@jimhimesjr we do some stuff with 4-jaw chucked into hydraulic 3-jaw on our CNC, first thing I do after getting the 4jaw chucked up I turn the pedal away from me, first thing my coworker said me when I was learning how to operate that lathe :D Well, got 250mm 4-jaw chucked into 250mm 3-jaw to make some face grooves into 6mm round alu plate with 4 mickey-mouses (professional term!) on it´s OD 90° apart.... pretty normal thing to mount a chuck into a chuck, nothing to be worried about

[@jimhimesjr]

@@piter_sk They typically had the pedal hidden but forgot to this one time. Daylight guy set the job up and 2nd shift guys hand got mangled on the first part change of his shift. Be careful is all I’m saying.

[@krissy4god]

Super nice video 👍🏻

[@semperfidelis8386]

If you machine after flame hardening, do you have to change speeds & feeds? Looked like it was machining just fine after hardening. How hard will it wind up after machining?

[@jimsvideos7201]

I don't know if it is a live center for a lathe but it looks like one.

I work on a vertical lathe with a 4 meter diameter bushing, I make high voltage electric motors

[@jimw5385]

Definitely a “measure twice cut once” situation

[@ChrisMaj]

Yeah, you got that right.

[@MattR963]

Is it awkward to tweak sizes with the conversation cycles on the fanuc controller? I never bothered to used them myself. Always used g71 and g70 cycles.

[@ChrisMaj]

Probably 80% of programming I do is on FANUC manual guide. You can quickly change between roughing and finishing cycles.

[@gredangeo]

Is that the same part on the horizontal lathe as the vertical one? The size of them seem so different.

[@ChrisMaj]

Yeah it's the same part.

[@dwest320]

Impressive to see that huge hula dance at the beginning to near zero deflection after your first top cut.

[@MachinedComponents]

Great vid as always, thanks Chris. In regard to that forging, is it not possible for them to have forged a tapper on it to give you a bit less to have to rough off?

[@ChrisMaj]

I've heard that it's difficult to get a tapper on a forging, especially something like this where there's nothing to grab on to, but I might be wrong.

[@christopherdean1326]

"TAPER" FFS! Seemed like a huge waste of time and material to me as well. Can't understand why the blank forging couldn't be a lot close to the finished shape than it was.

[@brettymike]

@@christopherdean1326 Maybe more expensive to forge the cone shape more, than to machine it?. And at least all the swarf is recyclable .

[@keithjurena9319]

That was an open die forging, the modern equivalent to what a blacksmith produced. Tapers like a Morse type are possible. But this shape is nigh impossible open die and would require a set of closed dies, a large expense.

[@Halinspark]

@@keithjurena9319 Easiest option I can think of would be casting, but that would mean different material properties that I'm assuming would not be ideal in this part.

[@shug831]

What's the cycle time for the roughing? There was some amount of material to remove on that blank.

[@ChrisMaj]

Tell you the truth, I don't remember. We are a repair shop so we don't count every second. I just have to get the job done.

Why did you opt out of using coolant during the rough turning?

[@scotttipps8155]

Probably to get a better filming with the camera instead of slinging coolant all over the place. Just a guess though

[@HettesKvek]

@@scotttipps8155 : Most modern video cameras have a zoom feature so the camera doesn't need to be near the subject. Just a bit of common 21st century information for ya' though.

Did you nail the 13.999 +.001 -.000 bore on the first pass? Or did you have to iterate? 🤔

[@ChrisMaj]

I usually take two finish cuts. There's no room for "maybe I'll get it the first time "

[@Andrey222ful]

@@ChrisMaj Great work. What's your trick to hold such close tolerance on those big parts. Also thanks for showing stuff, not just talking, like most machining channels do. There's only few KZbin channels, that show big heavy machining, only only couple that shows the setup and step by step process. Trade school/college would not teach you that.

[@ChrisMaj]

@@Andrey222ful There is no trick. First, hopefully your machine is in good shape that can handle tight tolerances and second, work on your measuring technique, make sure you get it right.

[@mikeep1000]

@@Andrey222ful Something that has helped me to hold a close tolerance on very costly parts is to add to the program a test cut of about half inch in length leaving about .01 to .015 stock, using same speed and feed as the actual finish cut. I measure that diameter to see how it compares to what I programed. Make an offset if needed and then I run my finish cut. 15 minutes to avoid the walk of shame to the front office ☹️

[@Andrey222ful]

@@mikeep1000 Thanks for the tip. What's your usually final pass? 0.005" or less, because if less then it rubs and leaves a bad sometimes uneven finish.
