My dad used to make lathes, much bigger than you saw, but nothing like the biggest. The biggest I know of can work 25m length and 7m diameter, but probably not at the same time. Waldrich Siegen Profi Turn H, if I spelled it right.

@@cageordie Yes, good point, the one I worked with could do a long length or a wide diameter but not both at the same time. There are ship yards making diesel (bunker oil actually) engines with crank shafts a hundred feet long or longer which means a HUGE lathe has to be involved.

Might have been a Monarch or American.

@cageordie there used to be a business called triggs mfg in city of commerce calif they had lathes that machined the metal o rings for rocket engines some were fifteen twenty feet or more in diameter they had to use a lift to load stock onto machine and also a catcher to get part as it was machined off was there when a operator failed to place his catcher...beheaded

@Brian some longer parts thread isn't cut its rolled between two mandrels some hot rolled others cold rolled

Hello from Tokyo! Thanks for your comment!

Hello from Tokyo! Thanks for your comment! It is a pity that there is no successor. The president's son used to work there, but he quit.

Hear ya have 47 years setting up different types screw machines and did prototype machining now no one wants to get hands dirty retire soon to my home workshop maybe when I pass grandson will take my machines

Why would you manually do something that a factory can do to better precision and on orders of magnitude greater volume

​@@wazaagbreak-head6039 The fact that he operates with a significant profit margin demonstrates the why someone would continue to use these old machines. The fact that you think this is what making screws manually looks like shows you don't know much about it. These screw machines are all automatic, hence why a single guy can produce millions of screws all by himself. And I'm sure his screws are more than accurate enough.

@@wazaagbreak-head6039screws are still made this way today. Screws are not made in CNC machines. But screws can be made much cheaper from another place not far from this gentleman’s home…. I would proudly buy this man’s fasteners for my shop.

Yea ran those most of jobs we bid on weren't for parts was for chips...the brass

As I said, crappy UNC luckily nobody use outside NA.

Hello from Tokyo! Thanks for your comment. Yes, the president said that it is fully automatic and efficient.

Not all of them.

I know of one in stl

Rockford IL had a bunch when I was growing up

The US and Chinese trying to "screw" each other

Mill-Max has a large captive screw machine shop on Long Island, NY. They make all sorts of connector pins for electronics.

Hello from Tokyo! Thanks for your comment! That's one option, too. I think so.

Hello from Tokyo! Thanks for your comment!

After the war when they were occupied by the U.S. we helped them get back on the road to economic stability by teaching them SPC (Statistical Process Control). They embraced and improved it. Changing tooling just before it fails saves you a lot of scrap.

昔の機械というより、油の問題だね。 今は測定器の性能が向上してるから同じ粘度の潤滑油作りやすい。

@@user-zy2gy3bw5h 潤滑油の妄想始めたのはコメ主やろ？ この機械はそんなに繊細じゃねーよ。

Hello from Tokyo! Thanks for your comment! I'd be happy to entertain you with other videos as well.

Had my hand caught in a B&S screw machine. That was 40 years ago. I am still machining. Have 2 lathes, and 2 mills in my garage. Screw machines are on another level. Maybe now I could master one.

@Wild E. Coyote well fairly easy any brownie or cva..index davenport Acme just the matter of concept..been setting up 45 years sad to see the old dinosaurs phased out...most of reason is no longer tax deductible...cnc are but screw Mach is cheaper overall

@@miguelcastaneda7257 There's still things that good old screw machines and purpose built machines can do faster and more economical than modern CNC's. I worked @ John Deere as an electrical maintenance tech. about 10 years ago and they had a number of purpose built machines 40+ years old that they were still running because nothing modern could compete. Interestingly, they were still running a big old Warner & Swasey NC turret lathe (converted to CNC) made in the 70's because nothing modern could remove as much material/hr as that old behemoth. The increased productivity offset any tax benefits of replacing it. They had a lot of really cool, unique equipment there. Unfortunately, between the ridiculous union politics and Deere treating everybody like they're 5 years old, I couldn't take it and found a better job.

@Marc's Eclectic Stuff true at work I finally convinced them to blank out parts on brown and sharp screw machines they can run four five hundred a day then cnc do the burnishing making two hundred or more versus previous doing it all cnc lucky get fifty a day ...screw Mach only specialized tool is form everything else pershiable tooling drill cut off tool cams are pick up am on cncs now but did set up and reapair for forty plus years

Thank you! From Tokyo

Hello from Tokyo! Thanks for your comment. I agree with you. But the president said that one person is comfortable and good.

Hello from Tokyo! Thanks for your comment.

Thanks for the comment! I will let President Asai know!

oh , ja , wenn man bedenkt was hier schrauben kosten , zb , spaxschrauben im sonderpreis baumarkt , pro kilo 5 euro , was bekommt der hersteller

wow.

Hello from Tokyo! Thanks for your comment!

The old Machines . Righteously built !

Der Präsident dieser Fabrik sagte, dass sie rentabel ist, weil sie voll automatisiert ist und keine Arbeitskosten erfordert.

Hello from Tokyo! Thanks for your comment!

Oil mist.

@@rkgaustin9043 That makes sense..

コメントありがとうございます！今では貴重な歯切盤なんですね、素晴らしい

Hello from Tokyo! Thanks for your comment!

The president said that it is fully automatic and easy. However, he said that he would like to turn this factory into a museum in the future because there is no successor.

Hello from Tokyo! Thanks for your comment.

Near the beginning also, looks like small screws for 2.5"/ODD/floppy/etc.

Hello from Tokyo! Thanks for your comment. The president said that maintenance is easy. You are right 👍

Hello from Tokyo! Thanks for your comment! According to the president, he bought one for $4,000 60 years ago. Maintenance of the machine is also easy, just apply oil and replace consumable parts. He said it was a machine with good cost and performance.

Thanks for the comment!

You forget highballs and speedballs.

Hello from Tokyo! Thanks for your comment! This machine is made in Japan.
