Wow...I know that I am not supposed to be into this field of work, but I am. Love watching this...

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.

Finished product looks excellent....top- job Chris and collegues.

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

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

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

Жыл бұрын

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.

woohoo your lathe is back up and running

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?

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.

You must be a musician or something. After listening to it with my headphones you're kinda right.

How do you determine the size of the center hole? Do you have some rule of thumb depending on the weight of the part?

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

Жыл бұрын

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.

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.
