is the lead screws among other things in the Chinese mills would probably
have to be changed as they are not up to real mill standards.

I took a two semester course a few years ago in NC machine tool

programming.

When adding a Prototrak NC servo system to one of my mills,
it came with X and Y ballscrews to replace the factory threaded
bushing types.
