The Case For Additive Technology In EDM
Producing fine finishes on EDMed surfaces has long been a goal, especially for mold and die shops that operate ram-type electrical discharge machines. Lately, there has been renewed interest in using additives in the dielectric oil to achieve ultra fine finishes with graphite electrodes without excessive burn times.

Fine Wire Is Just Fine
As parts get smaller and smaller, using EDM wire as small as 0.001 inch in diameter to cut these workpieces becomes an attractive option—actually, the only option.
Read MoreUnattended, Short-Run Production Work Spurs EDM Shop's Growth, Productivity
The move into shortrun production projects is changing Advanced Machining's product mix, and Bobby Miller, Advanced's other co-owner, says it's good to be making this transition. The shop continues to receive custom, oneofakind jobs, but it's also garnering an increasing number of productiontype jobs that demand attention only until the first successful production parts come off. The latter situation is attractive, Mr. Miller explains, because at this point, it's just a matter of letting the machine run to process the parts.

A ram electrical discharge machine may not be the place most observers would expect to see a high-speed linear motor. Linear motors seem more appropriate for the axis drives of milling machines, where high feed rates complement high spindle speeds in high performance machining. But high performance is a goal for EDM builders as well.
