    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.

    Hand scraping is an art for the finest precision machine tools that require mechanical accuracy without compensation.

    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 !

    It would have been easier to assemble the machine without this step

    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?

    • @MatsuuraMachineryCorporation
      @MatsuuraMachineryCorporation  2 года назад +2

      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 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.
