Most motorized micrometers cost upwards of $700 per motor. This is a low cost version of commercially available micrometer actuators that uses a bipolar stepper motor allowing the micrometer to be controlled with readily available CNC control boards.
SEE "Micron_Actuators_Version_History.pdf" FOR CURRENT INFORMATION ON THE PROJECT!
Pairing these actuators with linear motion stage, a CNC machine with ~5um positional accuracy can be made for low cost.

this is great! You're probably aware of them, but I've had good luck with Kozak Micro Adjusters; maybe a bit cheaper, and available in super-fine, down to 50 microns/rev (!!)
I have not ran across them, I just looked at their screws and yeah looks very nice! Looks more expensive than the Thor Labs's a bit more coarse selection, but if the motion is ultimately limited by the thread pitch, I will look into Kozak's more.
