Re: [CAD_CAM_EDM_DRO] Was: Linear rail, accuracy in general

I don't think it'd be such a good idea to have all that swarf mixed in with
the coolant, and, just think of the logistics... a machine tool virtually
immersed in a small swimming pool. Just think of the possibility of getting
chips & dirt in the ballscrews!

Re: the water/coolant... Most (probably all) of the water-based cutting
fluids contain water-soluble oil(s), so iron-based parts don't usuallly
rust. In fact, if I let my parts 'air dry', when the water evaporates off,
a thin film of oil is left on the part, actually preventing rust from
forming.
