Knife Spindle / CNC LATHE

[@isaacmcmillen9246]

Love your work as always!

[@justuandmebb]

Nice to see you include some dimensions. Good work as usual.

[@ICA17887]

Super Job! Thanks Chris.

[@jimsvideos7201]

That is without a doubt the biggest saw arbor I have ever seen.

[@steveb1739]

Good job Chris. Nice Sagengewinde on the spindle nose!

[@shortribslongbow5312]

Beautiful work.

[@captcarlos]

Chris, nice vid. What heat treat was the material at. Couldn't have been too hard with the cuts and tool life. Thanks for sharing.

[@mauricioboldrin1512]

Amazing!!!!

[@sambor7433]

The 3 dislikes must be from welders. 👍

[@eugeniopizzorni]

Buongiorno MAESTRO MAJ. Complimenti 🤗🤗🤗🤗🤗😉😉😉😉👏👏👏👏👏👏👏👏👏👏👏👏

[@flothamm93]

Great Video! One question, why does it have to be grinded for threading? Newbie out here, sorry

[@flouserve]

Hello, a couple of questions, is that axis finished at Lathe or later rectified ?. Thanks

[@vivekdhameliya4633]

Which threading tool and insert are you using?

[@huntthornhill6713]

Nice work Chris! All I think is what a pain it would be to clean up all the chips, lol.

[@ChrisMaj]

Still better than bronze 😉

[@tiagobickel]

how many hours of machining this video? which model of this machine?

[@tojekonecna7450]

Nice 👍👍👍👍👍

[@ajose1239]

Which insert to use for buttress thread?

[@Cheeta666]

how do you like the fanuc EZ guide for prog? is it reliable? again, a really nice video Chris!

[@ChrisMaj]

Probably 80% programming I do with manual guide on the lathe and vtl and rest G-codes.

[@vasimansari6748]

Very good

[@waqasaslam360]

Love those chips

[@brandons9138]

Is there a center inside the chuck? I've never seen that before. How big is this machine/chuck?

[@ChrisMaj]

Yes there is a center in the chuck and it's 32" . Check out this video it's little bit more in detail kzbin.info/www/bejne/inqUi4aLicmKoLs

[@Peppins]

The machine has also two chucks!

[@sambor7433]

Top job as alway Chris. Keep it up. Love your vids mate. Always something big and unique how long did it take to turn up one part from stock to finish?

[@fuzzfacelogic789]

Do you use shims to get the correct tool height?

[@ChrisMaj]

The tool post is set up to 1 1/4" height and that's what most of my tools are.

[@dimwittflathead639]

If I wanted to hear music, I'd turn on the radio

[@ChrisMaj]

Ooo give me a break. There's like 30 seconds of music on the hyperlapse part and at the end when I'm showing some photos.

[@lancer2204]

Thanks for the vid, how often do you need to turn buttress threads?

[@ChrisMaj]

Not a lot, this is the only job that we get sometimes that has buttress threads.

[@smallcnclathes]

My cnc lathe weighs one third of that work piece!

[@IstasPumaNevada]

That hunk of starting metal weighs about 2/3rds as much as my first-gen Honda Insight. :D

[@markshutt6000]

Regarding all the stock removal, what is your insert life like?

[@ChrisMaj]

I guess you just have to find the right insert for the job.

[@markshutt6000]

....How many cutting edges did you use to rough cut ONE part?

[@ChrisMaj]

@@markshutt6000 I have made 4 of these and only used 2 corners.

[@markshutt6000]

That's awesome!! I run D2 for the most part (making pulverizer blades) in a mori seiki vl553 with live tooling. The roughing inserts last nearly the whole job. The finishers last around 8 parts. Cnmg 643 and 543 for roughing, and cnmg 433 for finishing. All Sandvik brand. They take some abuse! Thank you for making this content!!

[@judesisilangilang4465]

Very 👍🏼 nice What’s your feeds and speeds?

[@ChrisMaj]

0:28

[@judesisilangilang4465]

How did I miss that🤣 Thanks

[@iFailMW]

Is that an American butress thread? I`m kinda confused.

[@ChrisMaj]

Yes it is.

[@JRo250]

Very nice. If you could, can you post roughly what the raw materials cost in your videos? I think a lot of folks would be surprised. That piece you worked on is what, $5K + shipping?

[@ChrisMaj]

I don't have anything to do with ordering materials, so I don't really know the cost.

[@Sketch1994]

@@ChrisMaj Today I found out that my company prefers to lose jobs and customers than to fill me in on the job information. I am the only one in there with machining knowledge they try yo economically challenge every single step I take and they won't even tell me how many parts they are expecting. That way I never know how much time to devote to developping a mass production process and I end up giving machining times for flipping a 10 second part around 3 times myself. Also they have been sourcing materials and tools for 30+ years and have spent millions on them and even my single occasion suppliers almost halved the prices they were getting. I feel bad for even telling them when they asked me. Talk about a toxic relationship.

[@DineshKumar-fw2we]

Ur native place where

[@tpunclelee]

I don't think this is a CNC machine..the cutter fixing on manual turret and the chuck is a 4 jaws chuck?

[@ChrisMaj]

Looks like you haven't seen a lot of machines yet.

[@odgie5228]

So you ignored the fact that its running a program? It's a chuck, a fixture device and the 4 post is rigid, turrets are just an extra. This machine is producing amazing components and you don't even see it as a CNC.

[@parkerbirch1475]

Great music video. didn't even have to watch.

[@MiSt_PL]

Panie Chris, ile mocy ma silnik w tej tokarce?

[@ChrisMaj]

35Hp/26kW

[@MiSt_PL]

@@ChrisMaj Dzięki za odpowiedź :-) Na dniach mam do zrobienia dwa wały o masie ok 2 ton na tokarce - Boehringer VDF DUS 800 - gdzie jest silnik o mocy 46kW. Chyba jeszcze nie było na niej tak takiego ciężkiego detalu, dlatego pytam czy maszyna mniej więcej da radę - chociaż moment obrotowy na przekładni też ma znaczenie.

[@ChrisMaj]

@@MiSt_PL Na mojej tokarce zauważyłem że to średnica bardziej daje wycisk jak waga detalu. O wiele lżej jest obrabiać sztukę o średnicy 200mm x 3 metry niż 600mm x metr chyba że maszyna ma naprawdę niskie przełożenia.

[@MiSt_PL]

@@ChrisMaj To przez prędkość obwodową, im większa średnica tym większe opory. W takich sytuacjach ważny jest moment obrotowy, tak mi się przynajmniej wydaje :-)

[@mattcaesar5781]

Never cut buttress threads. Anything crazy about them?

[@Sketch1994]

Apart from starting to grind an ID tool the wrong way around, no... nothing crazy at all.

[@mehmettemel8725]

Me neither never needed to all these years I've been machining.

[@Sketch1994]

@@mehmettemel8725 I've seen some marine gas tank caps made of plastic with Butress threads on them. Seen it done once...

[@ChrisMaj]

In machinery, the buttress thread form is designed to handle extremely high axial thrust in one direction.

[@kennel1952]

長い太丸の中心に大きい貫通の穴を開ける場合普通によくあるNC旋盤の貫通穴直径で加工が難しいのはどれぐらいの穴径かなあ？😁それとも長さ？つまり、逆に長さでBTAやガンドリルの方が、メリットあるのは、長さでどのくらいかなあ？300mm以上かなあ？ケースバイケースだとは思うけど、そこら辺のだいたいのことを知りたいです😁🤡

[@perceive8159]

How many button pushers could make this manually from start to finish, no digital readouts, manual machines only, including key ways, drilled and tapped holes, threading, etc, and be able to hold tight tolerances and pass inspection! 😎If you think you have what it takes speak up 😁

[@Cheeta666]

why the competition where there isnt any ...
