WHEEL, CNC VTL / ROUGH & FINISH (Tokarka Karuzelowa, proces obrabiania kół)

[@fubartotale3389]

50 years a toolmaker and here I am, retired watching machining videos.

[@ChrisMaj]

I think it rubs on you. Thanks for taking the time to watch my videos, Chris.

When I was a young lad, Dad used to have a competition with me on who could get the longest swarf string with hand feed...nearly 60 and still use the same lathe...

[@bostedtap8399]

I always compare mild steel and medium carbon, or alloy steel to Cheese, mild steel is a stringy cheese, medium carbon is a hard cheese 🧀. Added lead or sulphur is Parmesan 🤔 That bore looked to have a great finish though. Great vlog, thanks for sharing.

[@familydahl4103]

Takes me back to when I operated a 48" vertical boring mill. We would get giant 2 part castings from the local foundry and "rough machine" the parts. The long hook to grab the chips of death was a reality.

[@davesalzer3220]

I still get a little anxious when that tool jumps to position over a spinning lump like it does. Great vid as usual.

[@brandonpaice4528]

You get used to it in cnc after a while

[@wilson12789]

sounds like a blanchard grinder ramping up to speed. awesome video!

[@jaredjohnson3043]

Nice work getting good finishes considering how stringy the chips were. We have the same issue with 2024 aluminum, it won't break a chip for nothing. Great video as always!

[@elanjacobs1]

What inserts and feed are you running?

[@julioalvarez6294]

Awesome videos !

[@ChrisMaj]

Thanks 👍

[@HP_rep_mek]

This was interesting to watch, thanks🙏

Qué velocidad de corte en vueltas por minuto avancé por vuelta Gracias maestro

Hey you guys are doing amazing work. Where is your factory

[@jifvlogs1151]

Nice work

[@ChrisMaj]

Glad you enjoyed 👍

[@dangerdave616]

How are the machine and tool loads on this machine? There's quite a lot of rotational inertia.

[@zainaltbq9469]

👍👍

[@geoffgreenhalgh3553]

I used to run 2 VTLs machining train wheels. No coolant. Dirty and very noisy.

[@notyou6950]

Vertical lathe. Tough machine.

[@janosfeher6314]

bigger feed?

[@forrestaddy9644]

I've watched several of your videos where you have considerable stock to remove yet you take light cuts given the apparent size and power of the machine tools you're using. What spindle HP do you have available. (Couldn't stand it. Had to edit out my condescension.)

[@ChrisMaj]

Well this machine is only 30 HP (22 Kw) most of my tools are 1.25"(31.75mm) and 1.00" (25.4mm) My average DOC is around 0.300"(7.6mm)FEED 0.025~0.030 IPR (0.635~0.762 mm/rev) I don't really do production work, it's mostly one-offs.

[@forrestaddy9644]

@@ChrisMaj OK. My bad. The spindle motor HP rules the productivity. Guess I was projecting. My previous (and unedited) comment looked snarky on second reading. Would you like me to delete it?

[@ChrisMaj]

@@forrestaddy9644 O no, don't worry about it.

[@HP_rep_mek]

@@forrestaddy9644 you willing to edit/delete your comment is not common on the internet these days, I salute you for changing your mind after getting more info from the author👍 It’s too easy to come out sounding as you know it all, but not really having all the info needed... I get this a lot on Instagram unfortunately: you really don’t have all the info and you can’t be so damn sure about how things should be done!

[@tuantq06]

Why did you not finish the op 1 in the first place? I’m curious. Were you afraid that op2 roughing would bend the wheel?

[@ChrisMaj]

Yeah, there was a lot of material removed, so I rather rough out the part before finishing.

[@jessefoulk]

Out of curiosity, are there surface grinders for this rotary configuration in the industry?

[@ChrisMaj]

That's all I found. I'm guessing that's what you meant. kzbin.info/www/bejne/i5vQY3yOaJ2gn7M

Czy to jest tokarka karuzelowa Goodway w USA znana pod marką Yama Seiki?

Dokładnie tak Yama Seiki GV-1600M

nice job chris - looks like some terrible material haha

[@dawszelka5461]

No jak się tak wiór ciągnie to jest masakra i widać ze to jakis glina a nie stal ... Przerabanie się to obrabia znam z doświadczenia

[@ChrisMaj]

Na tokarce jeszcze to wióro jakość złapiesz, na tej maszynie aż strach stać obok jak taki długi wiór zawinie i zacznie walić po maszynie.

The video shows that the operator has little experience.

[@kisspeteristvan]

@@StanislavPacourek because of the stringers ?

[@tristinknee5650]

All this video shows is that A27 is difficult to machine. It's super stringy steel. And for a one-off job, it doesn't make sense to go buy a whole new assortment of inserts with different chipbreakers.
