When I say 30 orders I mean 30 persons are very interesting to buy one (proto for the moment but final version will be
), they know me very well and they have confidence in me and my friend
. And yes on french forums but no pics of evolution available
EDM is a milling method without contact between metal and tool (electrode graphite). All is in a tank with fluid and we put a lot of current (electricity) between the 2 electrodes (bloc and graphite) and under sparks on whole bloc metal is vaporized in the fluid and we have a small hole. You can mill all metals, even the strongest on earth very easily with EDM
and precision is great (0.02mm during completion)
EDM is used to do sharp corner (impossible with a CNC) and complex geometry
