I’m glad there is still heavy industry around that needs these parts and somebody left that knows how to make them. Always fun to watch you work.

[@petrholan1321]

Since everybody wants everything cheap (who could blame them / us) there will always be heavy industry which will needs 2 + ton shafts And their managers will always wonder why it costs so much XD

Just what I need, new axles for my skate board. Great job as always.

[@ChrisMaj]

Now that has to be a big ass skate board.

[@shug831]

Nice. Used to work on old NC, Tape controlled vertical borers. Every block on the program could be a disaster waiting to happen. Would love to try modern CNC machining.

[@fokusano]

kupa roboty :) Jestem pod wrazeniem. Nigdy nie robilem na tokarce tak dlugiego walka, jedynie na frezarce kieszenie na klucze, ustawialem wtedy na kilku imadlach. Pan ma tutaj tylko 2 podparcia :D Nie bardzo moge sobie wyobrazic ze nie wystepywaly drgania, albo odchylki w wymiarze... Jestem pod wrazeniem :) Pozdrawiam

Haha sometimes you gotta improvise like you did with the surface roughness test. Great work.

You ever use a high rake insert for finishing? Ive used them seems to keep the stringers from wrapping up

[@NICK-uy3nl]

4340 Q&T is a very hard steel alloy, wondering how many inserts did you use for the entire job ?

[@ChrisMaj]

Two insert corners for rough turning and two for finishing cut. Once you get the feed, speed and right insert for the job, you don't really use many inserts.

[@NICK-uy3nl]

@@ChrisMaj - That's impressive. As you said, getting the feed and speed and insert type for the material is the key. Most machinists don't seem to get that right.

[@TheFeller1554]

@@NICK-uy3nl Early in the video he showed a speed feed calculator screen shot. I don't know if it's being in a hurry or arrogance but most guys don't enter their info into a calculator. Some of them are absolute rubbish, but if you find a good one it is the best use of two minutes in the whole job. It might not give you bang on numbers, but it will get you in the hunt real quick.

How did you turn that massive part without it bending and been out of centre from one end to the other,

As machinists we have a bright future !!

[@ChrisMaj]

O man, I don't know about that.

[@K-Effect]

It reminds me of what a gigantic diesel fuel injector would look like

[@sambor7433]

Another awesome big job mate. Love it. I dont machine to many shafts, more flange work and hosetails by male/female threads. Roughly what was the full machine cutting time Chris? 👍 nice work from one machinest to another.

[@ChrisMaj]

The thing with us being a repair shop, you start one job and then comes another "HOT JOB " you take everything down and get on it. In few days you come back to that part and hopefully you finish it.

Hey, I just noticed how your shoes look, do you have a second steel cap on the laces? Also love your stuff, watching your vids has gotten me out of trouble at work a couple times.

[@jimsvideos7201]

Those are called metatarsal protectors if you want to find some.

@@ChrisMaj Wow. Very nice job.

[@wendull811]

I have the same exact machine at my job except ours is the 8,000mm length. I absolutely love the machine. We did modify the tool post holder to take a quick change setup. I would love to do videos like yours but my work forbids it. Also wondering how you disabled the interlocks as ours has a massive door that is always in my way.

[@ChrisMaj]

So yours is twice as long, nice. I could use a 1,000 mm on my lathe cause they always get me these jobs that hardly fit. Remove the key from the door and insert it into that key pocket and attach it with a screw.

[@angelokharkiv]

Wonder !!!

[@johansrensen3291]

Wonder how much you have to compensate on X-axis, over the length of the part? Or does it turn completely straight?

[@ChrisMaj]

It depends on the diameter and length of the workpiece. kzbin.info/www/bejne/mmrPlqWGaN6rZqs

@@ChrisMaj Yea i see. Admiring your work 👍

[@Freser-qp5zc]

[@iamtemo]

What is the green paint for and how do you get the part already rough up like that?

[@ChrisMaj]

I'm guessing it's foundries way of identifying forgings. For bigger shafts we usually get them rough turned by the forging company.

[@Stubones999]

Do they have a lathe where there are two or more tool holders so you could be doing two separate jobs at the same time on the same part?

[@ChrisMaj]

We don't have that kind of a lathe.

Do you program the parts in G-code or Fanuc conversational?

[@ChrisMaj]

Most of my programming is done in fanuc conversational, but I also use G-codes.

[@julioalvarez6294]

@@ChrisMaj it’s very surprising as most shops don’t use or don’t know how to use the fanuc conversation part of the control

[@ChrisMaj]

@JULIO ALVAREZ I've noticed that people don't really like that fanuc manual guide. Most of my work is one-offs so all of the programming is done by hand on the machine. I really like the manual guide, you can do things that you can't with G-codes unless you're using some kind of programming software (Mastercam, fusion, etc)
