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.

It has to run, it's the money maker 🤣 Stay well Mr. Boschek.

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

[@ChrisMaj]

Entertaining, educational, I don't know about that but I'll take it. I appreciate it 👍

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...

[@marklowe330]

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.

[@ChrisMaj]

Yeah, 35 degree tool breaks the chip nicely, but you still have to hit the corners with grooving tool.

[@marklowe330]

@@ChrisMaj yes. I agree that most of the time you'll end up finishing with a grooving tool.

[@AllenORourke1954]

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...

[@ShainAndrews]

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.

[@ChrisMaj]

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.

[@duckslayer11000]

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.

[@ChrisMaj]

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.

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?

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 :)

[@ChrisMaj]

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.

[@ChrisMaj]

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.

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.

[@steinarne79]

How long can you keep one cutting edge, before it fails in such hard material?

[@ChrisMaj]

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.

[@steinarne79]

@@ChrisMaj thanks. Thats not bad ! But its a chuuuunky CNMG u had...probably a big radius on it. Makes it sturdy!
