No EDM= no additional set up, and EDM's a slow as hell=cheeperIf you have to drill a pilot, why not just broach it??? Rotary broach, sinker edm, etc.. Its neat, but I dont see it making huge waves in the CNC or manufacturing world. Looks hard on the machine and slow. The tooling dont look cheap either.
Damn ***** steal everything. i knew they couldn't come up with that themselvesI worked at a machine shop outside of detroit in 1988.It was owned by a bunch of old navy machinist.They said they made that setup long before I got there. They said it worked killer. Years later chanks stole ANOTHER american idea. These guys could make anything. I made some pretty killer stuff.Straight out of high school. Of course they set up the machine,I just ran them. But they were manual.
