Re: [CAD_CAM_EDM_DRO] Re: VFD? - what is this thing

Drives warehouse sells the Hitachi drives and others at a discounted price.
I have used several on the Bridgeport's and in other applications. Their
drives can also be purchased off of Ebay with no warranty for even less than
the advertised price from their website.

I have no affiliation just a satisfied customer...
