    Default Smallest thing I ever machined.

    Here's the smallest thing I ever designed and machined... you can barely see it against the drawing in the first piccy

    The second piccy has them near a ten pence pice for scale and the third shows it machining

    I managed to control the radius to 5um and the peak to valey on form to 0.2um. Lost a few on the floor though lol, if you drop them you got no chance hehe.

    I love deadlines- I like the whooshing sound they make as they fly by.

    They're clear too; it must make them easier to find : P

    pardon me for opening my mouth and sounding foolish...but what exactly are those things...what are they used for...and what purpose do they fill? Those are some pretty tight tolerances....

    So it appears the aluminum disc you showed the other day is involved in the manufacture of these teeny things. Pray tell, why such a b*****y big disc for such a small part? And for scale perhaps you could nip down to the money exchange and pick up a US quarter not one of them funny furrin coins you used.

    What are you guys talking about? I didn't see anything in those pictures...



    Really pretty amazing actually. You must wear a magnifying lens when working on those little babies.

    Hehe, they're optical antennas, used to focus light down onto a micro ccd for *mumbles* something I'm not allowed to say about.

    I made the ally disk that size so that I can use it on other jobs that might be bigger- the spindle has a vacuum going through it- so the whole plate acts like a vacuum chuck, but these parts are so small that the vacuum doesnt hold them... I have to use a scientificaly proven quick drying adhesive that can be removed rapidly causing minimum damage... "Tippex" (or typing correcting fluid lol).

    And yep, I use a jewlers loupe (magnifyer) to check the surface quality

    I love deadlines- I like the whooshing sound they make as they fly by.
