feel free to ask any questions the mill is a Bernardo KF25, it's controlled by USBCNC with most parts from damencnc, it still has the stock spindles but it's accurate at 1/1000th of a millimeter, I got the materials for a 4th rotating axis but didn't find the time yet to machine it.

but it's accurate at 1/1000th of a millimeter

A mill that's accurate to a micron. Frankly, that's hard to believe. How did you measure such precision?

I'm guessing that's 1 micron resolution.

I don't know the english word for this clocks but with 1 of those: http://www.minitechcnc.com/ind400-0001.jpg 1 rotation is 1mm

What kind of ballscrew for the axis?

 

[Mitch617]

I don't use ballscrews yet, the original trapezium spindles are used, ballscrews is a future plan since I need to modify a hell lot on the machine before they'll fit
