    Perfect machining

    Folks who machine metal like to make parts that fit together as perfectly as possible. So perfectly, in fact, that the joint disappears when the parts are assembled...

    That is as good as it can get, it has to be CNC machined, EDM wire and sink followed by some very skilled fitting and faces ground last.

    Disappearing part lines is approached by certain injection molds, reality and temperatures make zero nesting impractical. But while all the patterns in the video are super impressive, utilizing tapers could be part of the trick. But the gauge block effect at 1:21, holding air and adhering to lapped mate would be difficult to simulate physically.

    Very intensive use of technology and process planning of ultra stable material.
    Still not impressive as the German-Swiss apprentices hand filing a cube to slip fit a hand made square opening. All 6 ways.
    Spotting blue, spring calipers and a lot of time.

    According to their website, it's all CNC milled. They specialize in extremely close tolerances


    and delicate machining

    This shows that the "Chinese junk" we all complain about is not a reflection on their ability or skill, but rather on the specs/price requested by their clients (us.)

    If I quote a price to do a job or make a part, I don't offer 'levels of quality' depending on what price the customer would like to pay for it.
    It's either made right or it's not made at all.
