Hello
When EDM a surface finish ( VDI 20 /24 ) charmilles 20/24 . we sometimes get surface blotches or clouding on the surface. we have to clean the electrodes several times with a fine sand paper, re arrange flushing and hit the surface a few times to remove the discoloration. we only use copper electrodes in our shop . our machine is an older RoboForm 200.
any suggestions to improve finer finish.


Also a second question for burning sub gates. I have been told there are some older programs available for vectoring using allot of trig functions. these older programs were written by hand for these machines. If anyone happens to have one on a old disk or archived away . that would be great.


Thanks Gord
