You do nice work, Chris. Efficient, ordered, accurate, consistent, and, in effect, esthetically pleasing to those with the eye to appreciate such things.
I've always found it easier threading blind holes inside out, especially small diameters, where you can't really see anything. Honestly I'm surprised this isn't done more often, especially on manual machines without a kick out. Machining to a shoulder can be intimidating and exhausting for even the saltiest shop dog, all their bravado asidely. (Yes, I've done plenty of manual machining before youtube and cell phones 😅)
LOOOOOL @11:20 I actually felt phantom vibrations in my feet as ther big drill went in.. Am i brainwashed by my job? :D again.. your videos are amazing!
Beautiful precision work, Chris. On the long run, do you have to change inserts to hold the 6.500"/6.498" diameter? You really do amazing work. Very hypnotic and impressive. Thank you.
It's a little different for production work and one-offs. Us being a repair machine shop, sometimes I'll start a job then take it out cause something urgent comes in. I have to setup everything, write the program, and finish the work. Making just one piece always takes a little longer cause you have to check the program as you go.
Hast du vor dem linken Innengewinde einen Freistich am Anfang gemacht oder nicht? Weil du ansonsten mit der Gewindebohrstange immer ins Volle gestochen hättest. Deine Videos sind wie immer eine Freude 👍😉
No, nothing. He didn't post anything for about 2 years now, but I saw his comment on Titans a while ago, so I guess he's alright. I did ask him how is he, but he didn't reply back.
Honest question. A shaft that long, what was the first operation. How did you put the center in. Did you have to use a different machine before setting it up in the cnc lathe?
I figured that was how you started the shaft. I run a doosan 5100lmb that does not have a steady rest, yet. I've had to use a manual lathe for the centers or a boring mill. Thanks for the answer!
Most of the time, I'll leave 0.100" (2.54 mm) on diameter. On tight tolerances, I always take two cuts. First, just to make sure I'm not getting any taper, and then I'll do the final cut.
Loved the “oops, that’s a left hand thread” slight of hand lol.
Habit, before the brain catches on, it's L.H. thread 😅
Duas paixões para mim, usinagem e guitarra no final para fechar com chave de ouro.Parabens pelo canal,show!!

You make this look SO EASY! Great job and video from a dam Great machinist! Thanks for sharing 👍
Glad you enjoyed it.
@@ChrisMaj I learn from them. Thank you for sharing your techniques!
Turned out well, thanks for sharing 👍
Bravo! Beautiful work with a big, blind, left-hand threaded hole. Great job, Chris.
You just have to trust yourself that you entered the numbers correctly and hit that start button. 😅
Your machine handles some heavy cut's. Nice job!
Nice job Chris.
I miss CNC threading.
Although, it's more exciting to do internal left hand threads on a manual lathe!
Top Hand Quality Work Chris.
Thanks 👍
Beautiful work Chris. That left hand blind hole thread would have scared the shit out of me (on a manual lathe)
Why? I thread internal right hand threads that way all the time, threading away from the chuck is a piece of cake on a manual lathe.

I am pretty sure I have said this in the past, You and your company make some pretty interesting big parts.
I appreciate that!👍

Beautiful work, Chris 👌👌🇧🇷🇧🇷🇧🇷
Thank you so much 😀
good job you are awesome friends 👍

Usually, one insert corner will last for the entire piece, well, most of the time.
대한민국 한국기계공작하고 똑한네요?
한국기계 잘했습니다. 기술전수해 주고
쫑나고 돌아왔네요 .참 잘했습니다.
An interesting preparation for falling chips👍😃
Makes clean up a lot easier 😅
Perfect ❤
That thread was a dogs nuts of a fit Chris.
😅 thanks.
Tenho muitas saudades dos meus tempos de torneiro mecânico,estou com 71 anos mais ainda sei trabalhar.
A VOCAÇÃO ESTAS NO SANGUE, QUANDO GOSTAMOS DE ALGO, FAZEMOS COM MAESTRIA , ISSO NAO SE ESQUECE JAMAIS...
Great video Chris, for a job like that how long does it take start to finish, Regards Mark

Ja, es gibt einen Hinterschnitt auf der Rückseite, nur um es dem Gewindewerkzeug etwas leichter zu machen.
What Brand are the Inserat? Nice Chip flow!
Roughing- Kennametal, finishing- Korloy, threading- Iscar.
Thanks for sharing 👍
Thanks for watching
Vymakané...Nice...
What brand and model lathe is that?
Nice work.
Hankook PROTEC-9NC
Have you heard from Dave Wilkes? (UK trepanning guy). Haven’t heard from him for a while. Hope he’s OK
No, nothing. He didn't post anything for about 2 years now, but I saw his comment on Titans a while ago, so I guess he's alright. I did ask him how is he, but he didn't reply back.
Superior craftsmanship, like the runout was zero, not easy to do.
Does the lathe have a ball screw for X and Z or does it use (edit) a lead screw or helical rack with scales and backlash compensation?
ballscrews, of the ground variant
High precision ball screws for both axes.
Thats purdy
Honest question. A shaft that long, what was the first operation. How did you put the center in. Did you have to use a different machine before setting it up in the cnc lathe?
The centers were done on a horizontal boring mill, and the rest is in the video.

do you drill by hand with the wheel on the tailstock? or do you lock it to the carriage and run it as a cycle?
If I'm doing only one piece, I'll go by hand. If I'm doing more parts, then I'll use my toolpost attachment .
As threads go, that left-hand one is the strangest I've ever heard of.
Standard UNC pitch.
Our minds are not used to left-hand threads, I guess .
Nóż z płytką przekrzywiasz z jakiej przyczyny? Dla lepszej powierzchni?
Tak jak mowisz, przy toczeniu czołowym od mniejszej średnicy do większej wychodzi lepsza powierzchnia.
@@ChrisMaj tam oczywiście miało być "z płytką T" ale nie wiem dlaczego nie było 🤷🏻♂️
How much stock do you leave before the finishing pass on the tight tolerances?
Most of the time, I'll leave 0.100" (2.54 mm) on diameter. On tight tolerances, I always take two cuts. First, just to make sure I'm not getting any taper, and then I'll do the final cut.
@@ChrisMaj you are a master at your craft, and I appreciate your response
do you also use full profile thread inserts?
No, never. I like these much more. I can do any thread, any pitch with the same insert.
👍👍👍🤝
Which software you use for programming
Fanuc manual guide (conversational programming)
No FIX8 this time?
That's only for BIG JOBS 😉
What kind of insert use for thread?
Iscar TIP 5MT-0.25 IC908
Przyznaj, że lekki stresik był 12:58 😅😅
