you worked with two cnc at the same time preparing 20 times a day and programming for 10 years ending up with a heart attack and not being able to work anymore greetings from argentina great work of lathe
Whoa! Great to see the lathe up and running again. That's one big, fat shaft alright. Nice to see the final assembly and also the whole chock. Thanks for another excellent video.
Again…. Amazing, entertaining, educational, top notch quality work dude! Like everything else in life I do not believe that there are gurus at anything. What you see is years of experience, practice and tons of learning from your mistakes. I know first hand. I’m an engineer by trade and have 26 years doing this and have seen just about everything so they pay me great money for my experience. That cannot be had in a day or at school. Thanks man
@@geoffgreenhalgh3553 good for you Sir! I am having your trophy being made as we speak. Indeed some people aren't good to have an argument without trying to compete in silly ways. I love the channel though
Chris we used to do a similar type job back in the 80's. They had one of those rolls crack after a piece of cerawool ended up between the shaft and roll somehow. Never saw anything like that before or since...
@@ChrisMaj The Channel is Great Chris, i'm a Machinist myself but nowhere near the size of components you machine always fantastic to see your work...All the best Mark.
Great upload, as I watch your videos I often wonder about how you got to your current level of efficiency. Do you think you will ever do a video talking about your work history? I understand you may want to protect you privacy and also may not be able to talk about work you have done over the years, but I am curious nonetheless. Either way, thanks for sharing your knowledge.
It's no secret. I was born and raised in Poland, did almost 3 years of trade school all manual machining, didn't finish it though, cause my parents decided to move to US. Got here at 17, went to high school for 2 years, luckily I even graduated, but I knew college wasn't my thing and with only 2 years of English, college would have been hard. For couple of years I have worked here and there not really thinking about machining. Then I ended up in this shop, mostly manual machines. They had one vertical cnc machine which they got me running after a year or so. Poland is all metric so I had to learn imperial. Forward 25 years, and I'm still in the same shop but almost all cnc machines. I think I have gone through 4 lathes and that vtl in my videos. I know it's a long time in one shop but I like it. We do a lot of different stuff as you can tell from the videos, it's only 15 minutes drive from my house whichisplus. No one is breathing on my neck, no crazy production work. So yeah, that's about it.
Hey Chris, question for ya. Have you ever experienced any internal stress issues while machining? Some of those billets are significant and I'd think every once in a while you would cross one that starts acting up the more you machine. Have a good weekend. Thanks for bringing us along.
If you mean like cracks then no, but sometimes I'll be roughing some big piece and the shaft is perfectly straight. Then you do some different material, you take one small cut and the run-out is all over the place. It has to do a lot with the type of material, heat treatment and stress relief.
I want to see the surface plate you use for those things. Seriously though, how do you actually measure them? What kind of accuracy/tolerances do they need?
Oglądać fachowca przy pracy to sama przyjemność. Mam dwa pytania. Pierwsze, czy 4340 obrabia się dużo ciężej, niż 4140? Mówimy o Q+T do 34-36 HRC. Drugie, zastaniawiam się dlaczego wybrałeś akurat CNMG, a nie na przykład KNUX czy inną geometrię do ciężkiego toczenia zgrubnego. Czy wynika to z jej uniwersalności? Pozdrawiam serdecznie :)
4340 Obrabia się trochę ciężej co słychać przy toczeniu. Niektórzy mówią że jest "gęściejszy". Jakoś zawsze pod ręką były CNMG płytki i można je dostać po dosyć dobrej cenie. Niedawno dostałem nowy kennametal fix8 i nawet nie źle się spisuje, ale ten to raczej używam przy naprawdę ostrej jeździe. 😅 Krzysiek.
Ja używam do orki dnmg 150608 od sandvika i do finiszu mam drugi nóż z tą samą płytką. Do planowania mam cnmg widzę że ty również orasz cnmg jak ci się sprawdza ta płyteczka?
Przeważnie do zgrubnej obróbki używam CNMG644 i na gotowo TNMG432, DNMG432, VNMG432 zależy czy trzeba jakieś podtoczenia pod gwint albo coś takiego. Nie dawno doprosiłem się tego nowego kennametal fix8 i nawet nie źle to idzie.
I was an apprentice trained turner up till 40 years ago when I switched trades, how are you setting the tailstock to the centre line to achieve parallelism, do modern centre lathes have some sort of automatic setting..?? I'm 40 years out of touch here...
So, I noticed this part was rough turned... did y'all do that rough turning and send it out for destress/heat treat, or does it come to you already prepped like that?
Well, it depends on the material, inserts you are using, your feed/speed and riggity of your setup/machine. On this job I've used one insert corner to rough out both sides.
Turning to a ± 0.025mm tolerance on a Ø384mm shaft .... that takes a pretty good machine - and a pretty good machinist with lots of experience (if you hit those tolerances that is:) No thanks, I wouldn't like that stress. Pity these tradesmen - in most societies - don't get the respect (or remuneration) they deserve... because of ignorance I suppose.
All the money on measuring tool and someone is going to come out with a lidar system that will do it all in better - well just look at then toralences dead on every time

Ooo, there's a lot of keyboard experts.
This is always a beautiful sight! Thanks!
Greetings from Dresden! 👍👍👍🍻😎
Thanks for stopping by, cheers
those first cuts looked huge, but from the little I know the chips were just how they should be to make a nice finish and cut
Great piece of turning and impressive fitting by the Fitters too 👍well filmed thanks for sharing 👍
Yeah, it slipped right in. They didn't let me record. They said, if it stops half way, it's gonna be your fault 😅
@@ChrisMaj I hear you, every thing has to be right Shrink Fitting them big shafts,the way you stand, lucky shirt etc all important 👍
With wide deep groves I would rough them with a 35 degree tool. Another big job done. I like that you show it's more than one piece. I enjoy watching.
Yeah, 35 degree tool breaks the chip nicely, but you still have to hit the corners with grooving tool.
@@ChrisMaj yes. I agree that most of the time you'll end up finishing with a grooving tool.
Chris we used to do a similar type job back in the 80's. They had one of those rolls crack after a piece of cerawool ended up between the shaft and roll somehow. Never saw anything like that before or since...
Brilliant Chris, thanks for sharing 👍👌🇬🇧🇪🇺🇺🇦
Excellent content as always. It would also be very interesting to see how a specific portion of a rod like that is chrome plated.
Unfortunately we don't have the equipment to do that.

Szef mówi że za długo.
Very interesting. How thick is the chrome plating before the finish cut?

@@ChrisMaj Cheers Chris, must of missed that. I learn a lot from your videos, may it long continue
did anyone else think the cutting noise the grooving tool was making at 7:55 to 9:45 was a drum beat being played through a crappy speaker? lol
You must be a musician or something. After listening to it with my headphones you're kinda right.

Someone did his research 🤣
How do you determine the size of the center hole? Do you have some rule of thumb depending on the weight of the part?

Huge work
TAC Takisawa Machine very Good.
This is Hankook
how the hell do you chrome plate just one segment of a long shaft like that?
So, I noticed this part was rough turned... did y'all do that rough turning and send it out for destress/heat treat, or does it come to you already prepped like that?
We get them rough turned already.
Mega große Teile!!!
How long can you keep one cutting edge, before it fails in such hard material?
Well, it depends on the material, inserts you are using, your feed/speed and riggity of your setup/machine. On this job I've used one insert corner to rough out both sides.
@@ChrisMaj thanks. Thats not bad ! But its a chuuuunky CNMG u had...probably a big radius on it. Makes it sturdy!
So skilled
good video chris maj

Hello Sir. Your machine have just one tool offset how you can touch off finish tool offset?
There's 16 tool offsets, but I only have 4 tools post.

How you taking measurements include that too
