Great advantage for molds for polishing time and ease.


Not with that machine you won't.


The ones with the optional power supply would do a nice job ( about 12 Ra)
but compared to todays technology you wouldn't be able to afford the time.
Fully configured, a D-10 had three seperate power supplies in a single
cabinet as well as a little "add on" box that had to be plugged in.

When these machines came out, they were the cats ass. They would make a
great home machine today and they might be good for someone with little need
for EDM but compared to the latest and greatest they are an
electromechanical Rube Goldberg device.

I would not, however, want to have to get one fixed. Repair parts probably
cost more than the used machine would and you'll have one hell of a time
finding a service technician that knows what's up.


That's true, for Charmills, very difficult to get service and expensive.
We had to get guys from Chicago to fly out. Even than some young guy
showed up with a voltmeter, no experience, spending lot of time on the
phone how to fix the thing.
