Amazing craftsmanship. I have seen many Matsuura mills in shops that were running non stop production for decades without any problems. I still see some of the old red Matsuura machines around from time to time.
Ich habe ganz hohen Respekt vor japanischen Produkten, weil diese sehr hochwertige Fertigungen und Qualitätsansprüche an sich und Ihren Fertigungen haben. Das japanische Volk ist bei uns deutschen sehr hoch angesehen, da bekannt ist, das sie ihre Hochkultur seit tausenden von Jahren aufrecht erhalten haben. Japan hat eine Vielzahl an Produkten, die man - glücklicher Weise - nach Deutschland importieren kann. Womit aufgezeigt wird, das die Beziehungen zwischen Japan und Deutschland, seit sehr langer Zeit, sehr gut sind ! Meinen höchsten Respekt und Hochachtung an Alle, die uns unsere Beziehungen weiterhin ermöglichen und diese Produkte fertigen ! 20.03.´24
Interesting Japanese style of what we call "hip scraping." Labor-intensive and very satisfying with end result worth the extra effort. Excellent results!!
@@MatsuuraMachineryCorporation Then, I will tell you my standard: anything less than 1 arcsecond is irrelevant, and anything more than 3 arcseconds is more than relevant.
Is there any other method for achieving similar mating of surfaces? Let's say you would wire EDM a casting into two pieces, would you still have to scrape to achieve good contact?
Thank you for your comment! Do you mean cutting a casting into two pieces and putting them back? I believe, in that case, we ca have good contact surface. However, if we can have a casting of the whole structure in the first place, we would use it as it is.
@@MatsuuraMachineryCorporation Thank you for your reply. I was merely referring to the challenge of achieving a perfect mating surface. If I have understood correctly, wire edm is probably the most accurate cutting method but would one still require to scrape those surfaces - indicating there probably is no better way to mate two surfaces than hand scraping?
@@valkman761 Understood. Unfortunately, we are not sure of that. We do not have an EDM machine in our shop. If someone tries that, it would be very interesting!
@@valkman761 You would still have to scrape. Grinding is more accurate the EDM, and scraping is way more accurate than grinding. The only way that is as good as scraping is a metalized gap filling epoxy between the mating surfaces. This is called "replicating" the surfaces.
I still don't understand what the benefit of hand scraping It would have been easier to assemble the machine without this step Does this have anything to do with Flatness Surface ?
@@MatsuuraMachineryCorporation The book to read is "The Foundations Of Mechanical Accuracy' by Wayne R. Moore. It goes into things like self-proving methods and much more.
i understand scrapping is good but in todays worlds machine manufacturing like doosan and hwatchen only some area they scrabe and most of the area they use profile surface grinding .

Thank you! Honored to heat that! We can promise you that we would not change our way! Without compromise!
It's not easy to change geometry of assemblies by scraping especially large one. Respect guys!
Thank you for your comment! it is master craftsmanship indeed!
who said that? you juts need to be trained in that, and 15 minutes is enought
@@robertokandal it depends
legend has it that if you visit the matsuura workshop, you can hear the ghosts of all the workers who died before they could finish their scraping job
Hand scraping is an art for the finest precision machine tools that require mechanical accuracy without compensation.
Great work done by skilled Japanese masters of Metal ( Samurai's of Scraping ) - Arigato Goshimasta - Greetings from Copenhagen Denmark..! Mo ichi Do
Thank you for your comment! Indeed, they are Samurais! Some people name their own scraper like a Katana (Samurai sword).

Beautiful scraping! Thank you for sharing the process!
Thank you! Without Compromise!

Thank you for watching! Is that called "hip scraping" ? Interesting!
I think I understand why Japanese technology is the best in the world.
Thank you! The latest technologies and traditional techniques come together! this is something we can be proud of!
Que lindo trabajo. Que no se pierda el oficio.
What exactly is being used for blue and contrast? It looks excellent.
the company where I work in Italy has one... never a problem in 15 years
What is your accepted vertical tolerance for the column to lean forward/backward/sideways ? Thank you.
Unfortunately, the value differs according to the machine model, and it is classified.

Thank you for caring 🌹
It is interesting how were made first machine tools when there were no machine tools?
it's quite interesting topic!
@@MatsuuraMachineryCorporation can you make a video about it?

Men is seeking scrapping but does not get a job in the scrapping field.. 😢
Why not just use a whetstone ? Just curious.
Less accurate.
nice

”Komyotan” in Japanese.
