And yet we have a lathe that can do contact-lens cutting at optical accuracy (<= 10 nm, without a need for subsequent surface polishing). It can be done, but it is a lot of control work and quite expensive. -- Greetings Bertho (disclaimers are disclaimed) ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ Emc-developers mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-developers
