Ultra-high Precision Grinder

[@beatrute2677]

ultra precision surface grinding, now this really floats my boat.

This video barely scratches the surface. 😎

"i want people to know that if you're fascinated by a challenge you can make something wonderful, and that's a great way to live" 5:00

[@ActiveAtom]

I will never tier of great people that look at the same item in our lives some in our daily lives and see opportunity over acceptance, we are proud of this mans motivation, thank you for bringing it to our attention.

[@KnolltopFarms]

I loved his final comment...that IS a great way to live!

[@extradimension7356]

Meeee 2. +1

I was lucky enough to tour the Subaru telescope. It was amazing.

[@mackk123]

3:23 look at that shaper

[@samterian7694]

the coin trick was first used on USA (Bridgeport) Moore jig grinders

[@Tadesan]

sam terian Moore makes awesome equipment!

[@extradimension7356]

I had never seen that coin trick... Freaky ! But amazing hard to believe that is possible.

[@Gottenhimfella]

It's far more impressive when the item the coin is balancing on is being accelerated up and down at something approaching 1G In the Moore case, it was only the spindle and drive balance and bearing perfection which was being showcased. Here it's the quality and lack of hysteresis of the table ways, the ballscrews, their bearings, the motion control and the absence of lost motion, as well as the spindle and drive as previously.

How you know that "fact"?

[@davemorgen3045]

Great work shop but no groove grinder shots. Are they to small to see. Thanks

[@extradimension7356]

LOVE it ! Sad when he said "America was..." 'cuz we are not now :-(

[@Gottenhimfella]

@MrKalashnik0va They are not head and shoulders above the rest of the world as they once were. Same is true of Rolls Royce aero engines, German and Swiss machine tools, European cars, and the rocket motors of the USSR... It's always poignant when the glorious empires of yesteryear become tomorrow's has-beens ....

[@WS-ij1fu]

@MrKalashnik0va Boeing tours are fully booked right now - by lawyers.

[@extradimension7356]

@MrKalashnik0va Yeah they are using Okuma, Makino, Matsuura, Hermle, Okamoto, Studer, Hennig, Matsui Seiki, Mori Seiki / DMG, and Yasda (mother machines) as well as MAZAK and Nakamura Tome... on and on. Whereas HAAS machine made in the USA are trash and Hardinge basically sold out to China and Taiwan. But I'm pretty sure you already knew that re: machine tools , i.e. stuff that actually makes stuff. I'm a fan of what's left of the Moore Tool company that originally inspired the gentleman in the video who builds specialized grinding equipment.

[@extradimension7356]

@MrKalashnik0va Los Alamos labs just recently purchased a sh*t ton of OKUMA machine tools ! (made in Japan). Space X use some HAAS's but actually use HERMLE and Mitsui Seiki (German and Japanese machines).

[@extradimension7356]

@MrKalashnik0va Re: Okuma I know that first hand and is obviously not on the 'Interweb" . Hurco's are low -ish quality and the machines are manufactured in Taiwan (not bashing Taiwanese builders like Quaser) . . Additive manufacturing , nascent technologies that are being explored by all countries but again (for some more practical / industrial applications) need to be tied to a MAZAK, a DMG Mori, a HERMLE a Matsuura etc. etc. . The focus and theme of the Japanaology video was/ is Mr Masao Yamaguchi (for want of a better word) is an artisan and individual technical innovator (TAKUMI) that builds his own specialized grinding equipment. To the highest functional accuracies (If you understand anything about grinding and machine tools.). The USA started losing most of it's high quality machine tool companies by the late 1970's . Too expensive, unreliable and lacking in quality and long term precision and accuracy. I have a lot of respect for the Moore Tool company (in the USA) but it is a memory of what it used to be and used to be the last word in precision engineering. Instead the USA builds weapons systems using Japanese, Swiss and German machine tools. The "culture" of high precision machine tools and closely related processes are no longer to be found on US soil. It all has to be imported 99%. That is my point, and kind of Masao Yamaguchi's point in terms of competing on the world stage as an induvial who has committed his whole life to excellence in this one field of specific application. @MrKalashnik0va watch the video again.

[@Rabbitflyer5]

Wow, they can do normal mapping IRL now...

[@samterian7694]

Japan earnestly changed their culture in the early 50's before that they had no concept of precision

[@shawnbottom4769]

Ok? Explain a samurai sword or the extremely precise wood joinery of their temples. "Conceptually" they are superior to anything equivalent elsewhere.

[@janvanruth3485]

bullshit: 1 micrometer is approx. 0.00004 inch that is not precision grinding

[@chronokoks]

what is precision grinding then? you realize that after the 1/50 000 000 of an inch (1 micrometer) things can only get better with lapping and not grinding

[@janvanruth3485]

1 inch is 2.54 mm, how can 1/50 000 000 on an inch be 1 micrometer?

[@chronokoks]

1 micrometer has been in machining converted to either as 40 or 50 millionths of an inch. It's common machinist knowledge and you can even read about it in the book "Foundations of mechanical accuracy". You're welcome

[@janvanruth3485]

any machinist converting 1 mu to a 40 or 50 millionth of an inch and actually making precise parts using this conversion will be in deep trouble almost any measurement that is off by about 1.6 % will get the part out of tolerance

[@chronokoks]

european machinist usually try to fit into +-2 hundreths of millimeter.. americans are glad when they're within 2 thousands.. standard precision machining in europe is good within +-1 micron as a benchmark, old school US machinist like 50 millions of an inch - they often cite it if something is up to the tolerance of 50 millions, it means it's damn accurate. See the differences? When I indicate a part on a mill or a lathe i'm only satisfied with less than 1 hundredth of a mm while US folks are good with something less then 1 thousand of an inch even though 1 thousand of an inch is 2,54 x to 1 hundredth of a mm. If you don't do semiconductor making machines, specialized lab equipment and optics you're pretty good with 0,00004 inch or 0,00005 inch when you're comparing to a micron. It's simply just semantics in US vs EU precision standards/benchmarks. I could understand your precision elitism if you worked in ASML.
