Watching this, thinking, what's going on here? I don't know this guy so definitely didn't train him. Yet he's doing everything as I would and to the same standard. At 70 yrs young, watching this makes me smile.
I really wish that more people would watch videos like this so that they can see what goes into making the products that are used on a regular basis. But, then again, people like to whine and armchair quarterback and think that this is too much effort and that there ought to be better or faster ways to do things. I appreciate your letting us tag along with you as you work so that we can see the incredible things that you, and so many other skilled craftsmen do on a regular basis.
Not trying to be a keyboard warrior here, but the (im assuming) high feed mill is feeding quite slow. Yeah, its a decent diameter but still it seems slow for a HF mill 🤔
That was a 2" cutter with 1/2" round inserts. Yeah, he probably could have bump up the feed a little. That's not my department so I don't want to shove my nose in their business.
At first I thought: why are they using such a small cnc machine to make an automotive u-joint? Then I looked at the dimensions at the beginning of the video 😀. World's 🌎 largest truck 🚚 maybe?
Chris that is SERIOUSLY IMPRESSIVE WORK!!! Very well done my friend!! How long did it take you to get those four pieces done start to finish??? By the way I would have loved to be a fly on the wall to hear you you swearing in Polish that would have taken me back to my machine shop days 🤣🤣🤣🤣
I would consider it a nice/ extrem complicated pice, which combinats with a lot of fun and LEARING process. Would love to do something like that im my career once. Great work man always learning something from you on the way
Ув. Крис, восхитительная работа! Сложная, пространственная деталь, виработаная по требованиям и чертежа и естетики, кроме полезной является и очень красивой!
Great video mate, lovely bit of turning, love the whistling in the background, we machinist are a happy lot when it all goes to plan 😀 👍 thanks for sharing 👍
Some guys are not content making a cube with a lathe. They have to make crosses for the "views". I mean what is anybody going to do with a cross? Really nice work Chris. How many times did you have to measure and remeasure before you convinced yourself you were not manipulating the results in your favor?
It says 2012 on the print, so not that old compared to what I'm used to. Sometimes I'm looking at the old drawings and thinking, how the hell did they do that with only manual machines, but they did it. It might have taken a little longer, but they got the job done.
Ja jak mierze żeby oprawka była w osi to dostaje Joba a co dopiero ty musiałeś tam przeżywać jak na dwa zegary ustawiales hehe :D Szacunek :D detal wygląda świetnie :) Pozdro mistrzu :D
Beautiful piece of work! If you gave me that print it would definitely be half an hour and a coffee spent thinking it through, and I'd be tempted to make a 1/4-scale trial piece out of aluminium just to be sure.
That indicating reminds me of a part I used to cut on the boring mill. Flimsy 3 sided box with tight geometric tolerances milled on the "wings" 8 indicators, 4 under to monitor clamping distortion and 2 on the face of each wing to keep them from flaring out. Rough, release and reclamation. Took 5 minutes just to set the indicators up
What was the hardness/tensile strength of the material, and cutting parameters for the roughing? Looked like pretty tough stuff. Another job that Pete's Mazak would have been perfect for, I reckon.
Chris, love your work both on TH-cam and Reddit, just curious, was there a reason the counterbores were cut radially instead of axial? Keep up the great work, you do in my eyes some high level work!
I was wondering the same thing, why a g72 instead of a g71... but then I realised it gave him a better g70 finish pass at the end... I sometimes do things like that, it might be slower because you can’t take big cuts using just the point of the tool, but it gives you a better finish by running the tool over the whole profile from inside to out. If you did a g71 instead of a g72, you would either be stuck with a bas finish, or you would have to write a separate finish pass.
Boring bar looks oversize to fit the hole. He probably was taking depths equal to clearance angle between the part face and insert wall so the bar wouldn't rub the shank on the ID.
Actually the first piece I started cutting in Z-AXIS (axial) but after few cuts I've noticed that the part is moving a little. I slapped the indicator on it and yes, the indicator was moving over 0.010". I think what it was is that I didn't go crazy tight on the jaws, but then if I did get them really tight I couldn't get both indicators to run true.
Hi Chris im a little late watching this video, nice work as always! I have a similar job to do in a couple of weeks do you remember what tooling you used to do the roughing?

We're not seeing a lot of what goes on her, right? You're running NC programs for each dimension, right? You don't have an NC program start to finish....can't do that with a manual toolpost. You gotta put up your tool...touch it off.....run a cut....measure.....put in an offset....and run to the finish dimension of that tool, right? You have to do that for every tool...roughing...finishing...right? Doing a production run for a part like this must take forever.
Those are beautiful finishes, your speeds and feeds are superb! People don't give this trade enough credit, this is as much art as it is science.

FemTek vertical machining center and Hankook PROTEC-9NC

Truly some master level 4-jaw indicating there! Nice work!
I consider myself to be pretty good at indicating 4-jaw chuck, but this was challenging.
It's all master cam.....try conversation
That pallet picture of all four. That's a lot of dialing in!!
First one took the longest, then I got the hang of it.
At first I thought: why are they using such a small cnc machine to make an automotive u-joint? Then I looked at the dimensions at the beginning of the video 😀. World's 🌎 largest truck 🚚 maybe?
CAT 797 😉
@@ChrisMaj Cat 797, a 400-ton mine haul truck.
Fantastic work, that would have been a nightmare to dial in... looks awesome... great job
Idealne wideo👍
Вполне сложная деталь для изготовления ,наверняка долго отлаживали перед пуском в серию.

If you asked my boss, he would say "why it took so long ", but he's not the one 🤬🤬🤬 making it. 🤣

In case Chris is too busy to swear at the job in Polish I can fill in ;-)

Dear God I hope you got a solid model for that, and some poor soul didn't have to hand code it from the drawing...
Great video as always.
The drawing you see at the beginning of the video ,that's all we got. Mastercam for milling, hand programed for turning.
All that beautiful work, and it's placed on a raw pallet???
Ув. Крис, восхитительная работа! Сложная, пространственная деталь, виработаная по требованиям и чертежа и естетики, кроме полезной является и очень красивой!

So Awesome
Great video mate, lovely bit of turning, love the whistling in the background, we machinist are a happy lot when it all goes to plan 😀 👍 thanks for sharing 👍

Same with everything in life mate 👍
really good.. thanks your video

Really nice work Chris. How many times did you have to measure and remeasure before you convinced yourself you were not manipulating the results in your favor?
Me manipulating the results?🤭🤫 Nooooo🤣
How old was the print? Can you imagine doing that part before CNC? The milling would have taken forever.
It says 2012 on the print, so not that old compared to what I'm used to. Sometimes I'm looking at the old drawings and thinking, how the hell did they do that with only manual machines, but they did it. It might have taken a little longer, but they got the job done.

And bad language 😂
Ja jak mierze żeby oprawka była w osi to dostaje Joba a co dopiero ty musiałeś tam przeżywać jak na dwa zegary ustawiales hehe :D Szacunek :D detal wygląda świetnie :) Pozdro mistrzu :D
Uważam się za dosyć dobrego w ustawianiu detali w 4-szczekowym uchwycie, ale te cztery sztuki trochę dały popalić.
Sometimes with jobs like this setting up is more challenging than the actual machining. Well done, those parts look Beautiful!
Beautiful piece of work! If you gave me that print it would definitely be half an hour and a coffee spent thinking it through, and I'd be tempted to make a 1/4-scale trial piece out of aluminium just to be sure.
That would be a scary place to be. All that mass spinning with so little to hold on to and an open machine. Thanks for sharing. Charles
Buongiorno MAESTRO CHRIS. Un UOMO SENZA LIMITI. Complimenti per il tuo LAVORO. ARTISTA della MECCANICA 🔝🔝🔝🔝🔝🔝🔝🔝🔝👏👏👏👏👏👏👏👏👏🤗🤗🤗🙋♂️🙋♂️🙋♂️
Jewelry for an Amazon! What gorgeous work you do. Thank you for sharing this. Wishing you a restful and pleasant Sunday.
You are a very talented machinist. Thanks for video.

Impressive. Some expensive parts :)
Scary stuff, incredible skills Chris 😅
What was the hardness/tensile strength of the material, and cutting parameters for the roughing? Looked like pretty tough stuff. Another job that Pete's Mazak would have been perfect for, I reckon.
4340 forging, 300/340 BHN. I wrote the parameters somewhere when I was recording, but when I started editing the video I couldn't find it.
maybe it's better to give the part to a control and measuring machine, otherwise a lot of time is spent on measurements?)
patience game 😊
@Chris Maj What was your tolerance on critical dimensions, one thousands?
16:00 0.001", 0:01 0.002"
How many hours just in mill time?
O man, I don't remember. It's been over a year.
It's very interesting to see but I don't know what it's for
How does the machine "know" the position of each tool when you change them?
У всех нормальных стран всё в миллиметрах, и только у американцев в дюймах.
Pretty cool machining, if you ask me... : ) Ale tak właściwie, co to za ustrojstwo, if I may ask?
Nie mam pojęcia. Rysunek był tylko na te cztery sztuki
@@ChrisMaj Ah, top secret stuff, then... ;-)
11:00 The ID and face ware still too rough to indicate on..?
Chris! That's another excellent video and workmanship! Thanks for sharing.
What's the cutting depth and speed in F please, during the first phase?
Cant even imagine the hours in one much less 4. Amazing
never seen soft jaws held on with duct tape but if it works great
"Spot -on" is close enough for most of this work.Nicely done.
噢耶
Eine großartige Arbeit an einem ziemlich anspruchsvollen Teil! - Sehr gut! 👍👍👍😎
PS.: Was kostet so ein Teil? Billig wird es nicht sein.
Finanzen sind nicht meine Abteilung.
Hi. did u attach the part into an angle plate for the 3rd op?
Yes
serious parts. Serious workmanship. Awesome job man.
I follow you since long time and i think its the most beautiful parts you ve ever made
O stop it, I've done nicer things 😉
Prise de tête le réglage, bravo mr Chris
Coming from a background of the drawing side, I never tired of watching machinists
You'll find a lot of old drawings in my videos.
You Guys did an excellent job. Hats off.
Quality work and programming.
Nice job, i like your job👍👍👍.
Very nice video thanks for sharing. :o)
What kind of machine is this lathe? Its CNC but no turret.
Hankook PROTEC-9NC.

10:00 why didnt you do an MDI program with spindle orientation? would have been a lot quicker...
