[AT] EDM

[bloomis at charter.net]

I did commercial refrigeration for years. One place I serviced a chiller
that cooled the coolant and the Charmilles EDM machines where they were
cutting the molds for hard drive cases. Looked just like a hard drive but it
was only the molds. I see that Charmilles appears to have been acquired by
Georg Fischer, a Swiss industrial conglomerate.

I have heard they are amazing machines and have seen a little of the work
they do. When they make a cut it is as smooth as glass and extremely
accurate.  A guy at the coffee shop is part of a family that owns a tool and
dye shop in Detroit that employs about 38 men. His kids now run most of the
day to day operation although he keeps watch over some of it. He has now
become a multi-million dollar hobby farmer. A couple of years ago he told me
he still had a million and a half left to spend on the farm yet that year.
Back on topic; he told me they have 3 EDM machines
  at the shop. The ones he has he said were $40,000 each when bought. He
said consumables run about $18 an hour for each machine. He said you set
them at night and then leave and they run till the job is done.
