Large Rope Pulley | CNC VTL |

That is a lovely bit of turning 👍👌great video thanks for sharing 👍

I love seeing footage of this thing slowing down from high speed. So much momentum.

Just setting up the piece on the machine must be a whole masterclass on its own. That dial indicator was dead on 0.!

One of those days where you pray to your deity of choice that the chip conveyor doesn't fail.

From one machinist to another, you are very good at what you do.

Chris, you always post wonderful videos and do such a fantastic job. I love seeing your videos and can not wait for the next one.

Great work as always. I have always used round inserts myself for deep grooving, but have recently been using dnmg more and more for exactly the reason you gave

I znów elegancka robota ;) fajnie było by się od Pana uczyć, zdrówka

Excellent job, Chris.

Very cool! Largest diameter on a VTL I've seen in a long time. Thx!

Did the tapped holes have to be clocked to one another on each side? Really cool part. Looks like fun. Oh and how did you pump out the swimming pool? Cheers, Tom

Awesome as usual. Thanks again for the effort and work to post for us regular guys....

Another Great Video Chris.👍

Wow. That's a fancy pulley. Nice job!

I always look forward to the indicating. that thing just won't budge.

Damn, every time you turn it it always run at the centre, great job 👏🏻

Brawo! :)👏

Hey Chris, super Bauteil was du da gefertigt hast! 👍 Programmierst du selber an der Maschine? So ein Facharbeiter wie du einer bist, ist echt Goldwert! Mach weiter so mit deiner tollen Arbeit

Just beautiful work! Thanks for sharing

Excellent video!

Very cool! I think you should do a tour of your shop, if possible! Very cool machines, would love to see more of them!

Many thanks for this new great video ! I'm pleased to lurn all your technics with you and your vertical lathe. I have a question about the inserts. You always use "gold" inserts. Personnaly I have bought "nano blue" inserts" wich are very strong. Do you use them sometimes ? I have an old lathe (from years 1940, my neighbour gave it to me, it was from his grandad), but it is a very good lathe that is very precise, the clearance is abou 1/100 mm). Many thanks christophe

Beautiful part!

Well Done. I just wonder how you get the M16 positions spot on both sides as seen in the drawing.

One the best I have ever seen .hatts off.. Keep rocking ❤

Always nice to see a real craftsman at work.

@ 8:15 Did you face the top of the large red risers after mounting? Or are they hardened like 1,2,3 blocks?

Smooth as 🍻🇦🇺

A thing of beauty Chris.

Excellent!

Wouldn't have dared to finish both sides directly on such a large part, afraid of ending up with banana pulley.

Very nice work Chris. That machine makes a change from the usual centre lathe. How long did it take overall to machine?

Closer to art than hardware! Beautiful work. I'm curious whether you ever get invited by your customers to see you work in action?

that looks a lovely finish

Including set-up, how long did it take to machine? What grade steel is it?

Thanks for sharing 👍 That's one big rope pulley 😅

What a masterpiece

Thank you so much

travail parfait comme d'habitude, merci Chris et bravo👋👋👍👍

Guys always wondered how do you manually touch of a neutral tool like the DNMG for the pully? Touching of diameter pretty simple. Do people just touch of the tool shank and go halfway?

I like the round inserts for grooves like that. But they are indeed a bit picky about cutting data to get the chips to break properly.

0:39 - Only see the bore tolerance (and finish); all else per note on the drawing? 1:31 - My machines have nowhere near the rigidity yours do, but this sort of info is really helpful to tell me the limits of yours. As a punk kid at Cinti Mill lo, these many years ago, I asked how you tell a good machine tool from a bad one: "Weigh it." (this assumed some minimal level of quality/accuracy) 5:56 - Earlier, there was a groove near the 'bottom' of that radius; figured it would be gone by the time you took a finish cut. 7:10 - That's the "34" dim at 0:39? 7:38 - And that's the "24" same time stamp? 8:02 - Looks like the bore is *finished*. 10:56 - You got bragging rights. 16:42 - Watching the coolant rise until it's obvious that the drainage is outrunning supply. 17:26 - Looks to begin falling. 18:57 - Did not see these @0:39. 20:25 - I was wrong. 22:32 - So the m26 holes were added for clamping. 22:35 - Standing O. 22:55 - And better finish. 25:29 - Always a pleasure: TY.

Won’t it deform if you process the cross-section in the second process?

Is the coolant supposed to look like apple juice or are you actually using apple juice???

I'm gonna say it's a part for a ski lift or something similar?

Beautiful job

The Kennametal A4 style tools with the full rad are pretty great for cutting this kind of groove, but maybe not at this scale, i make 12-16" sheaves. the chip control and feedrates are much better than button tools as well.

Bonjour, une question peut-être un peu bête : pourquoi ne pas faire une ébauche de la poulie venue de fonderie ou forgée ? Il y aurait moins de copeaux et de temps d'usinage, non ?

Hello Chris , around 25rpm on the biggest dia ?

Wonderful, you must be worth your weight in gold to the company you work for.

I can't imagine what a CNC like that costs. Awesome video.

Chris the four 26MM holes you put in for the final operation, i didn't see in the print did you get permission for that or where they on the print, i also saw some large herring bone gears do you make them, i'm going through a gear box now that needs four made for it.

Какую смазку применяет токарь при на резании резьбы метчиком ?

Curious what industry ordered it.

Perfect

2000 lbs of chips, reminds me of a party I went to back in the 70’s.

Congratulations on the excellent work. 👏🏻 I would like to know how long it took in hours to carry out this machining?!

Super inspiring. Thanks for showing the drawing. Would be interesting to know the end use.

One got a true sense of the size of the job when you turned it over and you were standing next to it standing vertical. 😲

very nice work i also like dnmg to me the chip breaking is everything.

...And that's what we former computer technicians call Bloody Impressive. Especially the dial-ins.

glad those straps are strong af.... cause the way hes got it rigged that inner section of strap, hooked to the chain, is supporting all the weight of that steel.

Where will this pulley be used?

Had 10’ dia VTL at my first job. Closed loooong time ago

J'aime bien ce boulot

12:50 i love how you turned off the coolant because there's enough held in the part to keep the tool cool.

Good job super 👍

This coolant should look like that, or it's 10 years after it should be changed? I really want to throw up a little just from looking at it. Machining beautiful like always

Quanto tempo no gastou no gorne ?

Nice work. I see you indicate on the rim and show zero runout, but what about the face?

Giant project😮

How many hours did you have to put into this masterpiece?

Massive!

Superb.

Top! Brasil

where are you guys from?

How many day this job paid, crish?? Good tool program

Piekny komponent :) Przepraszam, ale kolor chłodziwa w maszynie paskudny :P Chyba dawno nie zmieniany? Pozdrawiam

Did you need to get both sides drillings into same position ? And how did you do it

beautiful

nice material

I work on a monstrous VTL lathe, for turning the casings of high voltage electric motors

Good job ! How long did this Pulley take to machine?

"I know, I know" LOL

I wonder what the raw material cost ?

Perfectly sensible dimensions and you had to covert it into barleycorns...

Did you program this with Cad or fanuc only?

That part is bigger than my Haas!!!!

How do you know that it is sitting on all four parallels the first time you put the finished side down?

Beautiful craftsmanship ❤

0.057mm (~0.002") tolerance on the center hole. I'd have a high pucker factor trying to hit that.

No i to jest wielki detal :D Chris jesteś mistrz :D ty napisz lepiej ile to obrabiałeś łacznie ;D

I like it 👍👍👍💪💪💪👏👏👏

I was wondering how you were going to hold it for the V part. Very nice

👍👍👍🤘

I am surprised that you didn't have to stress release the part prior to finishing it.

а что за стойка ?

....may want to get them to invest into some YG Prime taps and call it a day...or some form taps.

Can the VTL also perform milling operations?

Anyone know what kind of eadbuds / earplugs he's using?
