Re: [CAD_CAM_EDM_DRO] Higher performance systems

Josh,

Why do you want the high speed? If you need a big machine for production
work, there are a number on the market that would pay for themselves.

Companies like Multicam get high speeds and they use a Hiwin ball screw with
a rotating nut.

My big question is why do you want to build a fast machine?
