Chris you make this stuff look easy. I sure would like to have had a CNC machine in the old days for reparative work, but this one off stuff would have been allot easier with NC. really enjoy your videos with the actual drawings to see what folks like you are actually working from. Please keep the videos coming.
That's the type of machining I use to program and turn out before becoming disabled 8 years ago. Enjoyed watching as always as it reminds me of my machining days. Keep up the good fight.
Much appreciated. Viewers like when you explain things, I really don't have the time to do that. I wish my wife would do the editing for me like Karen does for Kurtis 🤣. It is what it is for now. Thanks for watching and Happy New Year. Cheers
Another great video on the bores to end the year 2022, thank you for all the great work you did to film your machining. I wish you a happy new year 2023 full of great videos. Thank you Chris and see you soon.
0:12 - The fold makes it look like there's another taper feature; nope. 10:47 - Using that part to accept some movement? A36 is an obvious choice to 'move' a bit without failing. 14:27 - The assembly is certainly taking axial thrust (see that 1700#/ft torque spec [shimmed, with the A36 cap 'yielding' to provide the operational torque?], upper right!), but the bearing at the 'outer' end (to the left) is designed primarily for radial loads. The pipe threaded holes (drawing at 5:35) and the 'oil grooves' (couple of places) tell us the bearings run in an oil bath; high speed rolling element bearing prefer a 'spray, so this likely operates
@@ChrisMaj Thanks, Chris, but I've been preparing and reading drawings for >60 years - I'd better get good at it. Not nearly at your level running those machines.
wish you a happy new year, as always a great video. In my workshop we turn parts similar to yours, but more than 0.4mm/rev and 6mm depht of cut is almost impossible on our machines in stainless steel🙄, so I'm always very impressed by your videos
For parts this large: how much oversize do you leave after roughing the part out? Do you take one or two 'finishing' passes? Thank you for the great videos.
For something like this I'll leave around 1/8" on diameter. Long shafts, large diameters I'll leave 1/4" then do semi-cut down to about 0.100" . Most of the time I'll take two finishing passes. I can't afford to scrap parts of this size.
@@ChrisMaj thank you. A 0.100 (or 2 0.050) finishing passes. LoL. On my lathe a 0.040 cut is huge. And my finishing passes are 0.005. Enjoy seeing how you do all the ops.
Hey Chris, you might have already answered this in the past, but my first question is how are your parts not tapered while machining? And also do you hand program each project?
For short parts like this, this lathe is doing really good, I might get 0.002" taper on longer shaft, but then I'll just compensate that in my program. Most of my programming is done with conversational programming and G-codes.
@1:56 Listening to that CNC spool up as it cuts still seems strange to me! I *know* it's to keep the SFM right, but I did all my (limited) machining on manual machines. And another question: @6:11 or so. What is that groove on the top of the tool holder for? I've seen them before, but I don't get what it's purpose could be. Or is that an "artifact" from a previous "event"?
There was a guy that used to work with me, he always tried to improve things, he made that groove to guide the coolant, but tell you the truth, it doesn't do shit 😅
@@ChrisMaj I can see that from the vid! That's why I asked about it. To me if there was a rounded groove it would flow better. As it is, it actually looks like it's dividing the coolant stream and actually *reducing* the coolant reaching the insert.
I Think the opposite . Conventional is easy, to learn programming is hard. Conventional u just hit la lever… Buy the way, I have my on conventional machine shop
See, I just don't understand how you do this. Don't you have to "dial in" your finishing tools? You can run a roughing NC program all day, but when it comes to the finishing pass with a different tool, how are you holding tight tolerances running an NC program? If the program is written to the finish dimension, and you gauge it and it's too big, what do you do.....run it again with an offset? If it's too small, then you got junk.

Fun times! I hope this was a satisfying way to mark the end of one year, and I hope 23 is a better one.
Let's just hope that it's not worse 😉

Hi Chris, nice work and nice pieces. i like to see flying chips, greetings from germany
Thanks 👍
Nice bit of turning 👌 thanks for sharing 👍
You bet
Gday Chris, thanks for all the great content throughout the year, all the very best for 2023, cheers

Same to you!

Great work, may I wish you and your family a safe New year.
Thanks for sharing.
Happy new year!
Great video Chris, nice set of components that fit together, Happy new year to you and your family.
Feliz año nuevo Chris, desde México. Admiro tu trabajo y siempre estoy atento a tus nuevos videos.
Thanks for sharing and Happy New Year to you and your family 👪
Happy new year!
Yay for new fancy machining vid!
good work !!!👍👍

Hey. Happy New Year. Greetz from 🇩🇪
Same to you!
great job
Be nice to see some of the tool setting and computer program setting for some of the turning operations.
Nice one . Cheers . 👍
Thanks for the visit

Красиво!!
Muy bueno, usa un programa con G71 en la primera? Saludos Chris que tengas un excelente año. Muy bueno sus enseñanzas. Muchas gracias
Todo se hace con programación conversacional.

Hey Chris, you might have already answered this in the past, but my first question is how are your parts not tapered while machining? And also do you hand program each project?
I think he uses Fanuc Manual Guide to program from what I’ve seen, easy to program a taper in there if your machine has one

Its probably to direct coolant to the tip of the insert

G code is so easy.....try conversational

@@emilgabor88 buddy read again, it doesnt say conventional. He means another way of programming.
@@thedutchgamerguy8580 sorry my bad…
@EMIL GABOR g code is just more labor intensive if you don't have an auto cad program
@@emilgabor88 conversational......not conventional
